A REVIEW OF THE 2006-2007 TROPICAL CYCLONE SEASON
FOR THE SOUTHERN HEMISPHERE
Following is a tabular summary of all the tropical depressions
and tropical cyclones which occurred in the Southern Hemisphere
between 1 July 2006 and 30 June 2007 as reported in the Monthly
Global Tropical Cyclone Summaries prepared by the author.
(1) Number - this is the sequential cyclone number assigned by JTWC
in Hawaii.
(2) Name - the name (if any) assigned by the responsible Tropical
Cyclone Warning Centre. For systems in the South Indian Ocean
west of 90E and in the Southwest Pacific east of 160E which were
unnamed, the alphanumeric designator applied by La Reunion or
Fiji, respectively, is given in this column.
(3) Dates - range of dates for which tracking information for the
cyclone is available in the Global Tropical Cyclone Tracks files
prepared by the author. The dates given in most cases refer to
the time the system was in warning status and generally do not
include the pre-depression stages of the disturbance.
(4) Pressure - Lowest central pressure (either estimated or recorded)
during the lifetime of the cyclone. An asterisk (*) following
the pressure indicates the reading was an actual measured
pressure. Central pressure is given in millibars, which is
numerically equivalent to hectopascals.
(5) MSW 1-min avg - maximum 1-minute average sustained windspeed in
knots as assigned by JTWC. An asterisk (*) following the MSW
indicates that it was an actual measured value.
(6) MSW 10-min avg - maximum 10-minute average sustained windspeed
in knots as assigned by the responsible Tropical Cyclone Warning
Centre. An asterisk (*) following the MSW indicates that it was
an actual measured value.
(7) Basins - tropical cyclone basins where the cyclone tracked during
its life:
SWI - Southwest Indian Ocean - West of 90E
AUW - Northwest Australia/Southeast Indian Ocean - 90E to 135E
AUE - Northeast Australia/Coral Sea - 135E to 160E
SPA - South Pacific Ocean - East of 160E
SAT - South Atlantic Ocean
A number in parentheses (e.g. (1) ) following an entry refers to
a note following the entries for the given basin. A separate table
is given for each of the four Southern Hemisphere basins.

ACTIVITY BY BASINS
ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico
Activity for June: 1 tropical storm
Sources of Information
----------------------
Most of the information presented below was obtained from the
various tropical cyclone products issued by the Tropical Prediction
Center/National Hurricane Center (TPC/NHC) in Miami, Florida:
discussions, public advisories, forecast/advisories, tropical weather
outlooks, special tropical disturbance statements, etc. Some
additional information may have been gleaned from the monthly
summaries prepared by the hurricane specialists and available on
TPC/NHC's website. All references to sustained winds imply a
1-minute averaging period unless otherwise noted.
Atlantic Tropical Activity for June
-----------------------------------
Over the period 1950-2006, the month of June has produced an average
of 0.54 NS per year--about one every other year. Tropical Storm Barry
formed on 1 June, the first day of the official Atlantic hurricane
season, making this the third consecutive June to produce a tropical
storm. The last such case occurred in 1964-1966. Over the 13-year
period 1995-2007, the month of June has produced an average of 0.69
NS per year--above the long-term average. However, the month of June
has not seen a hurricane since 1995, when Hurricane Allison formed early
in the month. Since 1950 the only intense hurricanes to form in June
were the deadly Audrey of 1957 and Alma of 1966. The drought-relieving
rains of Barry in Florida and southern Georgia far outweighed any minor
damage which the cyclone caused.

225 nm west-southwest of Key West, Florida.
4. Peak Intensity: June 02/0000 UTC, near 24.3N/85.2W, or about
260 nm southwest of Tampa, Florida. (It should be noted that
NHC's MSW was at 45 kts 02/0000 through 02/1500 UTC.)
5. Size: At its peak Tropical Storm Barry was a fairly small tropical
cyclone with gale radii of 80 nm in the northern semicircle and from
30-40 nm in the southern quadrants.
6. End of Track: June 05/1800 UTC, near 49.0N/68.0W, or inland in
eastern Canada near the mouth of the St. Lawrence River.
B. Synoptic History
-------------------
The official TPC/NHC storm report on Tropical Storm Barry is already
available online, and the very detailed Wikipedia report is also
available. Given that, there isn't any need to write much about Barry
here. Following is the short summary of Barry included in NHC's monthly
report for June, which should suffice.
"Tropical Storm Barry formed from a tropical wave that spawned a broad
area of low pressure near the eastern coast of the Yucatan Peninsula on
30 May. The LOW moved north-northeastward on 31 May and thunderstorm
activity gradually became more concentrated near the center early on
1 June. The organization continued to improve and a tropical depression
formed at 1200 UTC on 1 June, just northwest of the western tip of Cuba.
Six hours later the depression strengthened into a tropical storm.
"Barry reached a peak intensity of 50 kts at 0000 June 2 while
centered about 130 nm west-southwest of Dry Tortugas. Thereafter, strong
upper-level southwesterly winds resulted in weakening and Barry made
landfall in the Tampa Bay area as a tropical depression around 1400 UTC
2 June. Barry quickly lost tropical characteristics and became an
extratropical LOW while located over eastern Georgia early on 3 June.
The extratropical LOW intensified and moved northeastward along the East
Coast of the United States. The LOW was absorbed by a larger extra-
tropical system near the St. Lawrence River on 5 June. There were no
reports of deaths or significant damage associated with Barry."
The Wikipedia report notes that a surfer died in Pinellas County, FL,
in heavy surf kicked up by Barry, and that there were two indirect
fatalities in traffic accidents due to wet roads. Also, it should be
noted that no advisories were issued on Barry as a tropical depression.
The very first advisory on the system, issued at 2100 UTC on 1 June,
upgraded the system to a tropical storm.
Given that Andrea was a subtropical storm, the development of Tropical
Storm Barry on 1 June marks the first time since at least prior to 1950
that the first purely tropical storm of the season actually formed on the
day which kicks off the 6-month official Atlantic hurricane season. The
closest prior occasion was in 1968, when Hurricane Abby was named on
2 June. Alberto of 1982 and Allison of 1995 became tropical storms on
3 June. Tropical Storm Allison of 2001 was named on 5 June, and Alma of
1966 and Andrew of 1986 reached tropical storm intensity on 6 June.
A subtropical storm formed in 1997 on 1 June. No operational warnings
as a subtropical system were issued, but the system has been included in
the Best Tracks database. In 1953 Tropical Storm Alice, the first
Atlantic tropical cyclone to bear a feminine name, had formed on 25 May
and was near its peak intensity on 1 June. And in 1959, Tropical Storm
Arlene formed in late May and was a weakening depression inland in
Louisiana on 1 June.

*************************************************************************
NORTHEAST PACIFIC (NEP) - North Pacific Ocean East of Longitude 180
Activity for June: 1 tropical depression
Northeast Pacific Tropical Activity for June
--------------------------------------------
As the month of June opened, Tropical Storm Barbara was still active
in Eastern Pacific waters. The storm, which formed on 30 May, made
landfall in extreme southeastern Mexico near the Guatemalan border on
2 June. A report on Barbara may be found in the May summary.
No tropical storms or hurricane formed during the month--only one
short-lived tropical depression stirred Eastern Pacific waters. Since
the satellite era began around 1966, the only years which saw no June
tropical storms or hurricanes in the Northeast Pacific basin were 1969,
2004, 2006 and 2007. It is very interesting that three of these four
cases have occurred within the last three years. The 1971-2005 averages
for the month of June are: 2.1 NS, 1.0 H, 0.4 IH, 7.4 NSD, 2.7 HD, and
0.7 IHD. Even though the month of June has averaged one hurricane per
year, the last June hurricane was intense Hurricane Carlotta in 2000.
Tropical Depression 03E formed on 11 June several hundred miles south
of Cabo San Lucas and moved northwestward for a couple of days,
dissipating on the 13th. A short report on the depression, prepared by
James Franklin of TPC/NHD, is available at the following URL:
http://www.nhc.noaa.gov/2007epac.shtml>
*************************************************************************
NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180
Activity for June: 1 tropical depression **
** - classified as a tropical depression by JMA only
Northwest Pacific Tropical Activity for June
--------------------------------------------
For the first time since 2000, no tropical storm or typhoon stirred
the waters of the Western North Pacific basin during the month of June.
No named storm formed in June of 2005, but Typhoon Nesat/Dante, which
formed in late May, became an intense typhoon in early June and lasted
until almost the middle of the month. In June, 2000, no systems were
classified as tropical depressions by JTWC or JMA, but there was a
midget system with a lifetime of only a few hours which formed just
offshore from Hong Kong and moved inland over the city. The Hong Kong
observatory classified that system as a tropical depression, but a
38-kt 10-min mean wind recorded at Sai Kung indicated that the system
was possibly a tiny tropical storm. The story of that interesting
little system may be found in the summary for June, 2000. All the
information available to the author on that system was sent by Phil
Smith, an Australian who at the time was living in Hong Kong.
In June, 2007, no systems were classified as tropical depressions by
JTWC; however, one system was tracked as a weak tropical depression by
JMA in late June and early July. The system was first mentioned as a
tropical depression by JMA at 1200 UTC on 29 June when it was located
very deep in the tropics near 3.0N/148.0E, or several hundred miles to
the south-southeast of Guam. The depression drifted slowly westward,
but was dropped from the High Seas Bulletins after 30/0000 UTC. It
(presumably the same system) reappeared in the Bulletin issued at
0000 UTC on 2 July, being located near 6.0N/140.0E, or well to the
southwest of Guam. The depression was downgraded to a low-pressure
area at 03/0000 UTC near 8.0N/135.0E, but was followed by JMA on through
0600 UTC on 4 July when it was last referenced near 8.0N/132.0E. This
system was mentioned in JTWC's STWOs for several days but was always
listed as an area with 'poor' development potential. Vertical shear
remained too strong for the system to consolidate. No track for this
weak depression was included in the companion cyclone tracks file for
June.
The absence of any tropical storms or hurricanes also coincided with
a stormless June in the Northeast Pacific basin (except for May's
Tropical Storm Barbara which was still operating on the first two days
of the month). The last month of June not to produce any tropical
cyclone of tropical storm intensity anywhere in the North Pacific Ocean
occurred in 1969--which was a below-average year in both basins, but a
hyperactive season in the Atlantic basin.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea
Activity for June: 1 tropical cyclone of gale intensity **
1 tropical cyclone of storm intensity ++
1 super cyclonic storm
** - classified as a deep depression by IMD
++ - classified as a deep depression by IMD
Sources of Information
----------------------
Most of the information presented below is based upon tropical
cyclone warnings and significant tropical weather outlooks issued
by the Joint Typhoon Warning Center of the U. S. Air Force and
Navy (JTWC), located at Pearl Harbor, Hawaii. Occasionally some
information may be gleaned from the daily tropical weather outlooks
and other bulletins issued by the Indian Meteorological Department
(IMD), which is the World Meteorological Organization's Regional
Specialised Meteorological Centre (RSMC) for the basin.
The reported maximum sustained winds (MSW) are based on a 1-minute
averaging period, which is used by all U. S. civilian and military
weather services for tropical cyclone warnings. For synoptic
observations in the North Indian Ocean region, both 10-minute and
3-minute average winds are employed, but IMD makes no attempt to
modify the Dvorak scale for estimating tropical cyclone intensity;
hence, a 1-minute average MSW is implied. In the North Indian Ocean
basin JTWC usually does not initiate warnings until a system has
become well-organized and likely to attain tropical storm status
within 48 hours.
NOTE ON WIND AVERAGING TIMES IN THE NORTH INDIAN OCEAN
------------------------------------------------------
As a result of some discussion with one of the Wikipedia writers who
covers many Indian Ocean cyclones, I revisited the wind averaging issue
with Dr. O. P. Singh, formerly associated with RSMC New Delhi but now the
new Director of Satellite Meteorology in IMD. Dr. Singh reconfirmed what
is stated above--that IMD does not modify the Dvorak scale when
estimating the peak winds in tropical cyclones. This was very apparent
in some of the advisories on Super Cyclonic Storm Gonu in June which
gave the analyzed Dvorak CI number as well as the estimated maximum
sustained wind.
However, another party within IMD stated to the Wikipedia writer that
their cyclone winds were assumed to be 3-minute averages. Therefore, the
Wikipedia reports for the North Indian Ocean cyclones have been modified
to indicate that the official RSMC wind estimates are 3-minute averages.
Obviously, the difference between a peak 1-minute average and a peak
3-minute average would be negligible--far less than the average error
inherent in estimating tropical cyclone intensity using the Dvorak
method.
North Indian Ocean Tropical Activity for June
---------------------------------------------
Tropical cyclone activity in the North Indian Ocean basin was well
above normal in June, 2007, with three tropical cyclones of gale
intensity (based on JTWC's analysis) and one reaching hurricane
intensity. The last June to produce three tropical storms was in 1996,
when there was also one hurricane. Over the period 1981-2002, the
average number of June NS in the North Indian Ocean basin was 0.59 with
an average of 0.09 hurricanes.
The storm of hurricane intensity was Super Cyclonic Storm Gonu, which
became the most intense tropical cyclone ever tracked in the Arabian
Sea. The peak MSW estimates for this cyclone were 140 kts and 130 kts
from JTWC and IMD, respectively. There have been three previous
tropical cyclones in the North Indian Ocean basin for which JTWC's peak
MSW estimate reached 140 kts, but none higher. All these cases occurred
in the Bay of Bengal: Typhoon Gay (32W) in November, 1989; Tropical
Cyclone 02B in April, 1991; and Tropical Cyclone 05B in October, 1999.
Gonu was very destructive to the nation of Oman, and caused
considerable damage in Iran, also. Tropical Cyclones 03B and 04B formed
about one week apart in the central Bay of Bengal with each making
landfall in eastern India as tropical storms of moderate intensity.
(This is based on JTWC's analysis--IMD never upgraded either system to
cyclonic storm status.) TC-04B made landfall farther north and
dissipated over west-central India, but TC-03B's more southerly track
carried it out into the northern Arabian Sea where it regenerated into
a tropical cyclone. While IMD maintained the system at deep depression
status, JTWC upgraded the system to tropical storm status, and there is
some evidence that it neared or reached hurricane intensity. The
Pakistani Meteorological Service, apparently concerned because the
intensifying cyclone was approaching the coast of Pakistan, began
referring to the storm as Tropical Cyclone Yemyin in their warnings, and
the name was picked up by the media and given wide dissemination in the
press. However, IMD, who is the WMO's official RSMC for the basin, did
not name the system.
Reports on all three systems follow.

b. Dates: 1 - 7 June, 2007
c. Max Sust Winds: 130 kts (1-min avg per IMD)
140 kts (1-min avg per JTWC)
d. Min Cent Press: 920 hPa (estimate per IMD)
3. Beginning of Track: June 01/0000 UTC, near 14.2N/70.6E, or about
315 nm south-southwest of Mumbai, India, as referenced in a
satellite bulletin from JTWC.
4. Peak Intensity: June 04/1200 UTC, near 19.9N/64.1 E, or about 350 nm
east-southeast of Masirah Island off coast of Oman.
5. Size: At its peak Super Cyclonic Storm Gonu was a slightly-smaller-
than-average tropical cyclone with gales extending outward from the
center about 120-130 nm.
6. End of Track: June 07/1800 UTC, near 25.5N/58.1E, or very near the
southern coast of Iran.
B. Synoptic History
-------------------
1. Origin: Super Cyclonic Storm Gonu was the most intense tropical
cyclone ever tracked in the Arabian Sea, reaching an estimated peak
1-min avg MSW of 140 kts. The storm is also the strongest known
tropical cyclone to have struck the Arabian Peninsula, crossing the
easternmost tip of Oman with peak winds estimated at around 85 to
90 kts. Gonu also became the first known tropical cyclone to traverse
the Gulf of Oman. The cyclone severely affected the nation of Oman,
ranking as the worst natural disaster in the country's history. Gonu
also dealt a fairly significant blow to Iran, mainly in the form of
flooding.
Widespread convection persisted over the eastern Arabian Sea for
several days during late May, and on the 31st JTWC's STWO mentioned
that an area of convection with a well-defined mid-level circulation
and cyclic convection had persisted about 350 nm south of Mumbai,
India. There was no evidence of a LLCC at this time, and a 31/0058
UTC QuikScat pass indicated strong convergence on the western side
of a surface trough along the coast of India near 13N. Upper-level
analysis indicated that the disturbance lay in a region of low
vertical shear under the ridge axis running through central India.
An upper-level trough over the northern Arabian Sea was enhancing
divergence aloft.
The development potential was upgraded to 'fair' early on 1 June as
a LLCC had developed and had shown considerable consolidation. The
upper-level environment had also improved with vertical wind shear
lessening considerably. A TCFA was issued at 01/1030 UTC with the
system having remained quasi-stationary. Convection near the LLCC
remained cyclic in nature, but low-level inflow had increased into
the southeastern quadrant of the disturbance. Maximum winds were
estimated at 25-30 kts, which would qualify the system as a tropical
depression in the NWP basin. (JTWC does not use this terminology in
the NIO basin and normally does not issue warnings until the MSW has
reached 35 kts.) IMD initially classified the system as a depression
at 01/1800 UTC, and upgraded it to deep depression status at 0300 UTC
on 2 June.
2. General Description of Track: JTWC issued the first warning on
Tropical Cyclone 02A at 02/0000 UTC, locating the center approximately
370 nm southwest of Mumbai and moving westward at 7 kts. The system
was tracking along the southwestern periphery of a mid-level ridge
anchored over northwestern India. Low vertical shear and favorable
upper-level diffluence were enhancing factors for intensification,
but much drier air to the northwest of the cyclone was seen as an
inhibiting factor for significant intensification. At 0900 UTC the
IMD upgraded the depression to cyclonic storm status, assigning the
name Gonu.
The westward motion briefly became north-northeasterly later on the
2nd due to a mid-latitude shortwave trough over eastern Pakistan;
however, by 03/1200 UTC Gonu had resumed a steady northwesterly
motion which it would follow essentially for the rest of its life.
The storm had steadily intensified, and at 1200 UTC JTWC upgraded
Gonu to 65 kts. It was still felt that the entrainment of drier air
would limit intensification, but this was not to be the case. By
04/0000 UTC Gonu's winds had climbed to 115 kts, making it the first
intense tropical cyclone (MSW > 100 kts) in the Arabian Sea since
Tropical Cyclone 01A in May, 2001. It was felt that this would be
the storm's peak intensity with slow weakening forecast, but again,
this did not materialize. The MSW was bumped up to 130 kts six hours
later, and at 04/1200 UTC Gonu reached its estimated peak intensity
of 140 kts, making it the strongest cyclone to date observed in the
Arabian Sea. At the time the storm was centered approximately 380 nm
southeast of Muscat, Oman, tracking northwestward at 10 kts.
The cyclone maintained its peak intensity (per JTWC's warnings) for
12 hours before slowly beginning to weaken. IMD's peak intensity
estimate was 130 kts at 1500 UTC with an attendant estimated CP of
920 hPa. As Gonu continued tracking toward Oman, it slowly began
to weaken due to decreasing oceanic heat content and the entrainment
of drier air from the Arabian Peninsula. By 0000 UTC on 6 June the
MSW had dropped to 85 kts with the center of Gonu located about
100 nm southeast of Muscat, or just off the easternmost tip of Oman.
Cyclonic Storm Gonu continued on its northwesterly heading, skimming
along the coast of Oman as it moved into the Gulf of Oman. The
storm continued to steadily weaken with winds dropping below hurricane
intensity by 06/1800 UTC. JTWC issued its final warning on Gonu at
07/0600 UTC with the center located about 85 nm north-northwest of
Muscat, or just off the Iranian coast near the entrance to the Strait
of Hormuz. The winds had dropped by this time to 35 kts. The
weakening depression continued to meander in the area for a day or
so before dissipating. IMD also issued their final warning on Gonu
at 07/0600 UTC under the assumption that Gonu had crossed the coast
and moved inland. However, based on satellite fixes from JTWC and
AFWA, the center of Gonu never clearly moved inland into Iran but
rather lingered near the coast.
C. Meteorological Data
----------------------
Following are a few rainfall measurements posted to a discussion list
by Jonathan Vigh which he'd obtained from a website. For the 24-hour
period ending at 0000 UTC 7 June, Seeb International Airport near Muscat
recorded 70.0 mm; Rustaq, Oman, recorded 72.8 mm; Samail, Oman, measured
69.8 mm (ending at 0600 UTC); and Jask, Iran, recorded 69.0 mm. By way
of contrast, Oman's average June rainfall is 0.6 mm. (Thanks to
Jonathan for posting these.)
I wrote Derrick Herndon to see if he had any wind observations
available. Following is his reply:
"The strongest winds I could find were at Qalhat (41267) located at
22.7N/59.4E. The center passed just north of this station around 0000Z
on the 6th. The last observation was at 2100Z on the 5th with 340@49 kts
and 989 mb. The strongest winds from Muscat were at Seeb Apt (41256) at
06/1200Z with 280@24G45 kts and 993 mb. So nothing close to the center.
Ship DDSK at 06/000Z reported 060@42 kts and 1002 mb well NW of the
center. Ship VVCV had 270@45 kts and 1001.8 mb at 07/0600Z south of the
weakening center. That is all I have been able to find. The objective
estimates showed good agreement on 06/1200Z with our Satellite Consensus
method indicating 972 mb and 70 kts, in agreement with JTWC. The IR
indicated perhaps some modest re-intensification after interaction
with land but nothing robust enough to show up in the intensity
estimates. The trend was slow steady weakening."
(A special thanks for Derrick for sending the information.)
D. Damage and Casualties
------------------------
Cyclonic Storm Gonu led to the worst natural disaster on record in
Oman. Rainfall totals reached 610 mm near the coast. Power and
telephone lines were knocked out across the eastern part of the country,
and strong waves and heavy rainfall caused extensive damage along the
coastline. In Muscat, winds reached 54 kts, leaving the capital city
without power. However, little damage was reported in the nation's oil
fields. According to the Oman News Agency, the cyclone killed 49 persons
with an additional 27 reported missing four days later. Over 20,000
people were adversely affected by Cyclone Gonu, and damage in the country
was estimated at around $4 billion (2007 USD).
In the United Arab Emirates, large waves led to flooding in the
coastal city of Fujairah, forcing roads to be closed and traffic
diverted. Overall damage to the port was reported as severe. A boat
sank in the area, leaving its 10 passengers missing.
In Iran Gonu dropped moderate to heavy rainfall, including 74 mm in
the city of Chabahar, where winds reached 60 kts. Power outages were
reported and there was damage to some clay houses in the area. A storm
tide of 2 metres was reported in some locations. In Iran, the cyclone
was responsible for 23 deaths, including 20 from drowning. Damage was
estimated at $216 million (2007 USD).
The above information in this section was taken from the online
Wikipedia report on Super Cyclonic Storm Gonu. Much additional

TROPICAL CYCLONE
(TC-03B)
21 - 27 June
------------------------------------
A. General Information
----------------------
1. Identification
a. RSMC - India Meteorological Department (IMD), New Delhi
b. JTWC - Tropical Cyclone 03B
c. NAME - Not named officially (The Meteorological Service of
Pakistan unofficially named the storm Yemyin, and this
name was picked up by the media and given widespread
dissemination.)
2. Overview
a. Basins Affected: North Indian Ocean (NIO)
b. Dates: 21 - 27 June, 2007
c. Max Sust Winds: 30 kts (1-min avg per IMD)
50 kts (1-min avg per JTWC)
d. Min Cent Press: 986.8 hPa (recorded--see Section C)
3. Beginning of Track: June 21/0300 UTC, near 15.5N/86.0E, or about
200 nm southeast of Visakhapatnam, India, as referenced in a
bulletin issued by IMD.
4. Peak Intensity: June 26/0000 UTC, near 25.1N/65.2E, or about 100 nm
west of Karachi, Pakistan.
5. Size: At its peak Tropical Cyclone 03B was a smaller-than-average
cyclone with gale radii of about 100 nm in the southern quadrants
and 75 nm to the north.
6. End of Track: June 27/0600 UTC, near 27.7N/63.6E, or inland about
465 km northwest of Karachi, Pakistan.
B. Synoptic History
-------------------
1. Origin: An area of convection developed and persisted in the central
Bay of Bengal on 19 June about 165 nm east of the Andaman Islands.
Deep convection was increasing near a developing mid to low-level
circulation, and surface observations in the area had revealed 24-hour
pressure falls of 1.5 hPa. While the upper-level environment was
characterized by diffluent flow, a strong tropical easterly jet was
contributing to 20-30 kts of vertical shear. The disturbance drifted
slowly to the west, and by the next day the LLCC had consolidated some
and the potential for development was upped to 'fair'. Even though
the environment was still not particularly conducive for cyclogenesis,
surface pressures had continued to fall by about 2.0 hPa over the
previous 24 hours.
At 0300 UTC on 21 June, the IMD issued a bulletin upgrading the low-
pressure area to a depression with winds estimated at 25 kts. JTWC
issued a TCFA at 21/0730 UTC with the center estimated to be about
160 nm southeast of Visakhapatnam, India. Deep convection had
developed over the well-defined LLCC, and a 21/0016 UTC QuikScat
pass had indicated 30-kt surface winds. At 21/1200 UTC IMD classified
the system as a deep depression, and at the same time JTWC issued the
first warning on Tropical Cyclone 03B. The system was centered about
100 nm south-southeast of Visakhapatnam and moving west-northwestward
at 14 kts. Deep convection was located primarily over the south-
western quadrant of the LLCC. TC-03B was tracking westward along the
southern periphery of a mid to upper-level ridge over northern India.
2. General Description of Track: TC-03B subsequently moved westward and
inland into coastal Andhra Pradesh near Gannavaram around 0300 UTC on
22 June. IMD never classified the system above deep depression
status (28-33 kts), and the peak MSW estimated by JTWC was 35 kts.
It is interesting to note that (to the author's knowledge), neither
JTWC nor AFWA assigned Dvorak T-numbers higher than T2.0, and SAB
reached T2.5 only at 22/0230 UTC. However, Dr. Karl Hoarau performed
his own Dvorak analysis of TC-03B and concluded that the system peaked
at 45 kts around 22/0000 UTC, shortly before landfall in India.
Once inland the tropical cyclone weakened as it moved steadily north-
westward across the Indian subcontinent. By 1200 UTC on the 24th
the LLCC was still over land about 300 km northwest of Mumbai, but
was nearing the coastline. Convection was located west of the LLCC
where northwesterly flow from the system was converging with south-
westerly monsoonal flow. The strong low-level southwesterly flow
across the Arabian Sea was contributing to increased cyclonic
vorticity, and an upper-level analysis indicated that a 200-hPa
anticyclone over northern India was helping to reduce vertical shear.
By 1800 UTC the LLCC had reached the coast and convection was starting
to form over the center; hence, JTWC upped the development potential
to 'fair'. A TCFA was issued at 25/0000 UTC with the center over the
northern Arabian Sea in the presence of high oceanic heat content,
low vertical shear and excellent divergence aloft. JTWC re-initiated
warnings on TC-03B at 25/0600 UTC with the center located roughly
110 nm south of Karachi, Pakistan, and moving northwestward at 10 kts.
TC-03B continued its northwesterly trek toward the Pakistani coast
and slowly intensified. Based on JTWC's warnings, the cyclone peaked
at 50 kts at 26/0000 UTC when it was located approximately 100 nm
west-northwest of Karachi. A significant burst of convection had
occurred over the LLCC, leading to Dvorak intensity estimates of 45
to 55 kts. The center of TC-03B made landfall in southern Pakistan
around 26/0300 UTC a little over 160 km west-northwest of Karachi.
Of course, once inland the system began to steadily weaken. JTWC
issued their final warning at 1800 UTC with the center approximately
120 km west-northwest of Asni (also spelled Pasni), Pakistan.
There is considerable evidence that TC-03B reached hurricane intensity
prior to landfall in Pakistan (see Section C below). However, IMD
never classified the system as even a cyclonic storm, leaving it at
deep depression status. The IMD is the WMO-recognized RSMC for the
North Indian Ocean basin, and as such has the official responsibility
to name tropical systems. However, the Meteorological Service of
Pakistan named this system Tropical Cyclone Yemyin in their warnings,
and this name was picked up by the media and given wide dissemination
in various press releases and on websites. The word that the author
has received from a contact within IMD is that they do not recognize
the name Yemyin for this system, and that when IMD names the next
cyclonic storm in the North Indian Ocean, its name will be Yemyin.
C. Meteorological Observations
------------------------------
Around the time of TC-03B's initial landfall in eastern India, the
station at Masulipatnam (16.1N/81.1E) recorded a SLP of 986.8 hPa at
22/0000 UTC, suggesting that the system was likely stronger than a
minimal tropical storm.
Supporting the idea that TC-03B was of hurricane intensity when it
made its final landfall in Pakistan is an observation from Pasni (25.2N/
63.5E). The station, which was never in the eyewall, recorded a SLP of
987.1 hPa at 26/0600 UTC, about three hours after the center had made
landfall.
The above observations were sent by Karl Hoarau, and Karl also made
the following comments regarding TC-03B's intensity at landfall in
Pakistan (slightly edited):
"Nevertheless, my personal estimate gave an intensity near 65 kts at
0200Z today when the cyclone crossed the coast of Pakistan near Ormara
(25.3N/64.6E). The past history of the storm and the satellite pictures
(microwave + EIR) showed that the intensification did not break the
Dvorak constraints.
"In fact, the 0113Z AMSU data (NOAA 15) and the F13 and F15 MI
pictures (0210Z and 0323Z) showed a closed eye. Moreover, the station
of Pasni (25.2N/63.5E), which never was in the eyewall, recorded a SLP
of 987.1 hPa at 0600Z when TC-03B had already made landfall. The
Dvorak analysis yielded T4.0 based on a band of 1.2 deg on a LOG 10
spiral."
(A special thanks to Karl for sending the information.)
D. Damage and Casualties
------------------------
Tropical Cyclone 03B was a deadly storm. According to information
contained in the online Wikipedia report, gleaned from various press
articles, 140 persons died in India, and the death toll in Pakistan
is estimated to be between 900 and 1000, including over 200 in the
Karachi area from an outer band of the storm, 380 in Balochistan
Province, 250 in Sindh Province, and 100 in the Northwest Frontier
Province. Also, more than 80 persons were killed in floods associated
with the remnants of TC-03B in Afghanistan.

TROPICAL CYCLONE
(TC-04B)
27 June - 1 July
------------------------------------
A. General Information
----------------------
1. Identification
a. RSMC - India Meteorological Department (IMD), New Delhi
b. JTWC - Tropical Cyclone 04B
c. NAME - None
2. Overview
a. Basins Affected: North Indian Ocean (NIO)
b. Dates: 27 June - 1 July, 2007
c. Max Sust Winds: 30 kts (1-min avg per IMD)
45 kts (1-min avg per JTWC)
d. Min Cent Press: 982.8 hPa (recorded--see Section C)
3. Beginning of Track: June 27/0000 UTC, near 17.2N/89.0E, or about
325 nm south-southeast of Calcutta, India, as referenced in a
satellite bulletin issued by AFWA.
4. Peak Intensity: June 28/1800 UTC, 19.0N/86.3E, or about 90 nm
south-southeast of Calcutta, India. (JTWC's peak intensity was
at 45 kts from 28/1800 through 29/1200 UTC.)
5. Size: At its peak Tropical Cyclone 04B was an average-sized,
somewhat asymmetrical cyclone with gale radii ranging from 110 nm
in the northeast quadrant to 210 nm in the southeast quadrant.
6. End of Track: July 01/0000 UTC, near 23.0N/77.7E, or inland about
675 km northeast of Mumbai, India.
B. Synoptic History
-------------------
1. Origin: About a week after the precursor of TC-03B had formed
in the central Bay of Bengal, another disturbance appeared in the
same general area, although a couple hundred miles farther north.
On 27 June an area of convection was located roughly 300 nm east of
Visakhapatnam, India. Satellite imagery depicted a partially-exposed
LLCC with deep convective banding organizing and wrapping into the
eastern quadrant. The LLCC was broad and vertical shear was moderate.
Since the disturbance was forecast to move into a more favorable
environment, JTWC upped the development potential to 'fair'. At
0730 UTC on 28 June, exactly one week after a TCFA had been issued
for TC-03B, JTWC issued a TCFA for the current disturbance. The
center had migrated westward to a point about 180 nm east of Visak-
hapatnam. Convective banding features had become better organized,
and synoptic observations from the coast of India were indicating
pressure falls. Vertical shear had decreased and an upper-level
anticyclone was developing over the system. IMD had classified the
developing system as a depression at 28/0000 UTC, and had upgraded it
to deep depression status three hours later.
2. General Description of Track: JTWC issued the first warning on
Tropical Cyclone 04B at 1200 UTC on 28 June, placing the center about
170 nm east of Visakhapatnam. The system was tracking toward the
north-northwest at 8 kts, having taken a northerly turn due to the
steering influence of low to mid-level ridging to the east. The
initial warning intensity was 35 kts, and some strengthening was
forecast due to favorable upper-level diffluence and a slight decrease
in vertical shear. Based on Dvorak estimates of T3.0/3.0 from both
JTWC and AFWA, the MSW had likely increased to 45 kts by 1800 UTC.
This intensity was maintained until landfall just south of Bhubaneswar
just after 29/0000 UTC. Around the time of landfall TC-04B turned
more to the northwest, and this track continued as the system slowly
weakened while moving across northern India. The remnants of TC-04B
reached the vicinity of Bhopal by around 0000 UTC on 1 July and
persisted over northwestern India for a few more days. This system
followed a more northerly track than its predecessor and did not move
out over the Arabian Sea. It should be noted that, as with TC-03B,
the IMD did not classify this system above the deep depression stage,
meaning that no name was assigned.
C. Meteorological Observations
------------------------------
The station of Bhubaneswar (WMO 42971, 20.2N/85.8E) recorded a minimum
SLP of 982.8 hPa at 0000 UTC on 29 June. This was around the time that
TC-04B made landfall just south of Bhubaneswar. (Thanks to Karl Hoarau
for sending this piece of information.)
According to the Wikipedia report, Mumbai recorded 243 mm of rain in
association with the remnants of TC-04B, and up to 462 mm was measured
at a location in the Bharuch District of Gujarat State.
D. Damage and Casualties
------------------------
The Wikipedia report states that deep convection associated with the
remnants of the cyclone brought heavy rains to Maharashtra with at
least 43 persons killed in the state. Also, 14 persons died in Gujarat
State due to flooding.

Australian East Coast LOWs in June
----------------------------------
A series of severe storm events pommeled the Australian East Coast
during June. While these type systems are not tropical, they often
exhibit some of the characteristics of subtropical or hybrid cyclones.
By far the main event was the LOW of 5-10 June, and this one drew on
a plume of tropical moisture flowing down across Queensland. Carl
Smith, who lives on Queensland's Gold Coast near Brisbane, has put
together a webpage with an exhaustive history of the main storm event
in early June, replete with narrative, photos, satellite imagery, radar
loops, and links to newspaper articles. This LOW was responsible for
a major snowfall event in northern New South Wales, a region which
normally receives little snow. Michael Bath, a storm chaser and media
reporter who lives near Lismore, NSW, went snow chasing and made some
very nice photos of the snow from the Northern Tablelands. Many of
Michael's photos, as well as a description of some of his experiences,
are included on Carl's webpage.

SPECIAL FEATURE - SOURCES OF TROPICAL CYCLONE INFORMATION
The purpose of this section is to list some websites where many and
varied types of tropical cyclone information are archived. Many readers
will know about these already, but for the benefit of those who don't,
I wanted to include them.
(1) Aircraft Reconnaissance Information
---------------------------------------
Various types of messages from reconnaissance aircraft may be
retrieved from the following FTP site:
ftp://ftp.nhc.noaa.gov/pub/products/nhc/recon/>
Information regarding how to interpret the coded reconnaissance
messages may be found at the following URL:
http://www.nhc.noaa.gov/reconlist.shtml>
Links are also included to websites with further information about the
U. S. Air Force 53rd Weather Reconnaissance Squadron and the NOAA Air-
craft Operations Center.
(2) Archived Advisories
-----------------------
All the advisory products (public advisories, forecast/advisories,
strike probabilities, discussions, various graphics) issued by TPC/NHC
are archived on TPC's website. For the current year (using 2004 as an
example), the archived products can be found at:
http://www.nhc.noaa.gov/archive/2004/index.shtml>
Links to tropical products archives for earlier years are available at
the following URL:

JTWC warnings for past storms are archived on the NRL Monterrey website:
http://www.nrlmry.navy.mil/tc_pages/tc_home.html>
On the NRL site, the link to past years can be found in the upper left
corner of the screen.
I am not aware at the moment of any other TCWC which archives all
its tropical cyclone warning/advisory products for public access, but
if I learn of any, I will add them to this list.
(3) Satellite Imagery
---------------------
Satellite images of tropical cyclones in various sensor bands are
available on the NRL Monterrey and University of Wisconsin websites,
courtesy of Jeff Hawkins and Chris Velden and their associates. The
links are:

(4) Cyclone Tracking Information
--------------------------------
There is a U. S. Navy site that tracks tropical cyclones at 6-hourly
intervals which often includes pre and post-advisory positions. The
link to the site is:
http://www.nrlmry.navy.mil/atcf_web/doc_archives/>
These tracks are often updated as further analysis occurs and may be
considered as sort of a working "best track".
Steve Young has compiled many of these tracks onto a single webpage
which is very user-friendly:
http://home.earthlink.net/~shy9/tc1.htm>
I'm sure there are other sites with available imagery available, and
as I learn of them, I will add the links to this list.

EXTRA FEATURE
In order to shorten the amount of typing in preparing the narrative
material, I have been in the habit of freely using abbreviations and
acronyms. I have tried to define most of these with the first usage
in a given summary, but I may have missed one now and then. Most of
these are probably understood by a majority of readers but perhaps a
few aren't clear to some. To remedy this I developed a Glossary of
Abbreviations and Acronyms which I first included in the August, 1998
summary. I don't normally include the Glossary in most months in
order to help keep them from being too long. If anyone would like to
receive a copy of the Glossary, please e-mail me and I'll be happy
to send them a copy.
*************************************************************************
AUTHOR'S NOTE: This summary should be considered a very preliminary
overview of the tropical cyclones that occur in each month. The cyclone
tracks (provided separately) will generally be based upon operational
warnings issued by the various tropical cyclone warning centers. The
information contained therein may differ somewhat from the tracking and
intensity information obtained from a "best-track" file which is based
on a detailed post-seasonal analysis of all available data. Information
on where to find official "best-track" files from the various warning
centers will be passed along from time to time.
The track files are not being sent via e-mail. They can be retrieved
from the archive sites listed below. (Note: I do have a limited e-mail
distribution list for the track files. If anyone wishes to receive
these via e-mail, please send me a message.)
Both the summaries and the track files are standard text files
created in DOS editor. Download to disk and use a viewer such as
Notepad or DOS editor to view the files.
The first summary in this series covered the month of October,
1997. Back issues can be obtained from the following websites
