                       FOR THE NORTHERN HEMISPHERE

     Following is a tabular summary of all the tropical depressions,
  tropical storms, hurricanes, and typhoons which occurred in the
  Northern Hemisphere between 1 January and 31 December 2007, as
  reported in the Monthly Global Tropical Cyclone Summaries prepared
  by the author.

    (1) Number - this is the sequential cyclone number assigned by either
                 TPC/NHC, CPHC in Honolulu, or JTWC.  If neither of these
                 agencies issued any warnings, no number will be given.

    (2) Name - the name (if any) assigned by either TPC/NHC, CPHC, IMD,
               or JMA (and PAGASA for Western North Pacific systems in 
               their area of warning responsibility).

    (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.

    (4) Pressure - Lowest central pressure (either estimated or recorded)
                   during the lifetime of the cyclone.  For Atlantic and
                   Northeastern Pacific systems these will be the values
                   reported in operational advisories from TPC/NHC or
                   CPHC.  For Northwest Pacific systems the central
                   pressure estimates are taken from advisories issued by
                   the Japanese Meteorological Agency.  An asterisk (*)
                   following the pressure indicates the reading was an
                   actual measured pressure normally obtained by a drop-
                   sonde released during an aerial reconnaissance
                   flight.    Central pressure is given in millibars,
                   which is numerically equivalent to hectopascals.

    (5) MSW - maximum 1-minute average sustained windspeed in knots.
              For the Northwestern Pacific and North Indian Ocean
              basins, these will be the highest value assigned
              operationally by JTWC.  For the Atlantic and Northeastern
              Pacific basins, the MSW values are taken from the
              official tropical cyclone reports prepared by the
              TPC/NHC Hurricane Specialists and which are available
              on TPC/NHC's website:>.

    (6) Basins - tropical cyclone basins where the cyclone tracked during
                 its life:

                 ATL - North Atlantic, Gulf of Mexico, Caribbean Sea
                 NEP - North Pacific east of Longitude 180
                 NWP - North Pacific west of Longitude 180
                       (including South China Sea)
                 NIO - Bay of Bengal and Arabian Sea

     For tropical systems in the NWP basin, two additional columns of
  information are given:

     (1) The tropical storm serial number assigned by the Japanese
         Meteorological Agency to tropical depressions which are deemed
         to have reached tropical storm intensity.  This does not always
         agree with JTWC's assessment.

     (2) An estimate of the maximum 10-minute average sustained wind.
         The value given represents the highest 10-min avg MSW assigned
         by any agency.  If from any warning center other than JMA, a
         numbered note below identifies which center's value is given.

     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 Northern Hemisphere basins.

  (1) System was a subtropical storm which never acquired full tropical
      characteristics.  The max winds/min pressure given above are for
      the subtropical portion of its life only.  The parent extratropical
      cyclone from which Andrea evolved produced winds exceeding hurricane

  (2) The peak winds during the lifetime of Tropical Storm Erin occurred
      during a brief and very surprising intensification episode over
      Oklahoma hundreds of miles inland and three days after landfall on
      the Texas coast.  NHC has officially not classified this phase of
      Erin's life as a tropical storm, but there are some meteorologists
      who disagree with this assessment.

  (3) Upgraded to a hurricane during post-storm analysis.

  (4) System was initially named as a subtropical storm but made the
      transition into a tropical cyclone.

  (5) Winds reached 75 kts after Noel had become, or at least was in the
      process of becoming, an extratropical cyclone.

  (6) System was a non-tropical LOW south of the Azores that developed
      organized convection.  It looked best on 29 December when satellite
      intensity estimates were 35-40 kts, and may have been a subtropical
      storm that day before merging with a front and weakening on the 30th.
      (Comments from Jack Beven.)  Drifting buoy 62901 reported a pressure
      of 1004.6 mb at 31/0000 UTC very near the low-level center, and an
      ASCAT pass around the same time revealed a few 45-kt wind vectors
      near the swath edge in the northwestern semicircle, where the
      pressure gradient would be tightest due to high pressure centered
      to the northwest.

  (1) Dr. Karl Hoarau performed his own analysis of Typhoon Man-yi and
      does not believe that it reached 130 kts, but rather peaked at
      125 kts (1-min avg).

  (2) Classified as a tropical depression by JMA only.

  (3) The times of JTWC's and JMA's respective peak intensities do not
      coincide.  When JMA was estimating 65 kts (10-min avg), JTWC's peak
      MSW was 80 kts (1-min avg).  At the time of JTWC's peak 1-min avg
      MSW of 85 kts, JMA's 10-min avg MSW was 60 kts.

  (4) This system was classified as Tropical Storm Hanna well before it was
      officially named Lekima by JMA, by which time it had moved westward
      out of PAGASA's AOR.

  (5) No warnings were issued on TS Haiyan by JTWC.  The 1-min avg MSW
      estimates were sent to the author by Dr. Karl Hoarau.
  (6) No warnings were issued on TS Podul by JTWC.  The 1-min avg MSW
      estimates were sent to the author by Dr. Karl Hoarau.

  (7) The peak 1-min avg MSW of 45 kts was estimated by Dr. Karl Hoarau
      during a time prior to warnings being issued on this system by any
      agency.   The peak operational 1-min avg MSW assigned by JTWC was
      35 kts, concurrent with the peak 10-min avg of 45 kts assigned by

  (8) Dr. Karl Hoarau performed a Dvorak analysis of TY Kajiki and estimates
      the peak 1-min avg MSW at 125 kts.

  (9) The times of JTWC's and JMA's respective peak intensities do not
      coincide.  When JMA was estimating 80 kts (10-min avg), JTWC's peak
      MSW was 90 kts (1-min avg).  At the time of JTWC's peak 1-min avg
      MSW of 95 kts, JMA's 10-min avg MSW was 75 kts.
  (10) While JTWC's peak 1-min avg MSW was only 25 kts, several SAB
       satellite fix bulletins rated the system at T2.0/2.0, suggesting
       that the depression produced 30-kt winds at some point.  JMA never
       referenced this system in their High Seas bulletins, even as a
       low-pressure area.  According to Dr. Karl Hoarau, microwave imagery
       clearly indicated the presence of a LLCC.

  (11) JTWC issued only two warnings on this system, and the highest MSW
       was only 25 kts.  Rather unusual, given that the translational speed
       was 29 kts!  Dr. Karl Hoarau estimates that the MSW peaked at 35 kts,
       and I included that value in the track I prepared.  The Dvorak
       estimates from JTWC's own satellite analyst reached T2.5/2.5 for
       several hours, and one SAB rating reached T3.0/3.0.  There was ample
       evidence from satellite imagery, plus the rapid forward motion, to
       believe that this system was a tropical storm.  JMA never elevated
       the system above weak depression status.

  (1) This system was not officially named operationally by IMD, who has
      official naming responsibility for the NIO basin.  However, the
      Pakistani Meteorological Service unofficially named the storm Yemyin
      and this name was given wide dissemination by the press.  Later, IMD
      re-analyzed the system to have been of cyclone intensity and made
      the decision to officially let the name Yemyin stand.  The highest
      MSW assigned to Yemyin by JTWC was 50 kts, but based on most Dvorak
      intensity estimates, microwave imagery, and at least one SLP
      observation a few hours after landfall, the storm was likely of
      hurricane intensity when it made landfall in Pakistan.

  (2) Dr. Karl Hoarau believes that Sidr peaked at 140 kts.

                             ACTIVITY BY BASINS

  ATLANTIC (ATL) - North Atlantic Ocean, Caribbean Sea, Gulf of Mexico

  Activity for June:  No tropical cyclones

                    Atlantic Tropical Activity for June

     Other than the presence of Tropical Storm Arthur inland over the
  southern Yucatan Peninsula at the beginning of the month, no tropical
  cyclones operated in Atlantic waters during June.  During the latter
  week of the month, and very curious feature was observed in equatorial
  regions of the eastern Atlantic:  a small vortex with a clockwise
  rotation north (barely) of the equator!  Some images of this feature 
  may be found at the following URL:>

     According to Scott Bachmeier, the imagery seems to suggest that the
  source of the vortex may have been an area of convection over the
  tropical Atlantic Ocean, centered around 1.5S/28.0W on 24 June.  This
  convection produced an outflow boundary, which could be seen propagating
  northwestward on the 24/1145 and 24/1445 UTC visible images.  The vortex
  first becomes apparent in the visible image at 1745 UTC, located some
  distance behind the aforementioned outflow boundary.  The vortex then
  becomes difficult to follow, until it is again obvious on the 1145 UTC
  visible image on 26 June (located near 0.5N/33.5W).  From that time, the
  feature is more easily tracked using the 30-min interval images at the
  above link.  


  NORTHEAST PACIFIC (NEP) - North Pacific Ocean East of Longitude 180

  Activity for June:  1 tropical storm
                      1 hurricane

                          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 (or the
  Central Pacific Hurricane Center (CPHC) in Honolulu, Hawaii, for
  locations west of longitude 140W):  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


                            HURRICANE BORIS
                            27 June - 4 July

     Tropical Storm Boris developed from an area of low pressure
  associated with an easterly wave which had departed the coast of West
  Africa on 15 June.  The system moved across the tropical North Atlantic
  as a high-amplitude disturbance, crossing into the Northeast Pacific
  basin on 23 June.  Convection slowly became organized during the next
  few days as the wave continued moving slowly westward.  The system
  developed into Tropical Depression 02E early on 27 June while located
  about 495 nm south-southwest of Manzanillo, Mexico.  Later the same
  day, TD-02E strengthened into Tropical Storm Boris.  Boris moved
  generally westward during the next two days with little change in
  intensity.  On the 29th the cyclone strengthened to 60 kts with a
  ragged eye apparent for several hours.   Boris maintained near-hurricane
  strength on 30 June and became the Eastern Pacific's first hurricane
  of the 2008 season at 0600 UTC on 1 July while located approximately
  990 nm west-southwest of the southern tip of Baja California.  Boris
  never intensified above minimal hurricane strength and soon began to
  weaken due to the effects of cooler SSTs.  The hurricane was downgraded
  to a tropical storm at 02/1800 UTC, and further weakened to a tropical
  depression on the 3rd.  Boris' remnants degenerated into a remnant LOW
  on 4 July located about 1235 nm west-southwest of the southern tip of
  Baja California.

     No damage or casualties are known to have resulted from Hurricane

                          TROPICAL STORM CRISTINA
                             27 June - 1 July

     Tropical Storm Cristina's origins lay in a tropical wave which crossed
  Central America on 21 June and moved into the Northeast Pacific basin
  on the 22nd.  For the next few days an area of showers and thunderstorms
  associated with the wave moved westward within the ITCZ with little
  change in organization.  By 26 June the cloud pattern associated with the
  system began to increase in organization, and Tropical Depression 03E
  formed on the 27th about 915 nm southwest of the southern tip of Baja
  California.  TD-03E initially moved west-northwestward and strengthened
  into a tropical storm on 28 June while turning toward the west.  Cristina
  reached a peak intensity of 45 kts early on the 29th, but weakened into
  a tropical depression the next day.   By early on 1 July the former
  tropical cyclone was a dissipating remnant LOW--the final TPC/NHC
  advisory placed the center near 14.1N/133.2W at 0300 UTC on 1 July.

     No damage or casualties are known to have resulted from Tropical
  Storm Cristina.

  NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180

  Activity for June:  1 typhoon

                          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.   In the companion
  tropical cyclone tracks file, I normally annotate track coordinates
  from some of the various Asian warning centers when their center
  positions differ from JTWC's by usually 40-50 nm or more.   All
  references to sustained winds imply a 1-minute averaging period
  unless otherwise noted.

     Michael V. Padua of Naga City in the Philippines, owner of the
  Typhoon 2000 website, normally sends me cyclone tracks based upon
  warnings issued by the Japanese Meteorological Agency (JMA) and the
  Philippines' Atmospheric, Geophysical & Astronomical Services
  Administration (PAGASA).  A very special thanks to Michael for the 
  assistance he so reliably provides.

     In the title line for each storm I have referenced all the cyclone
  names/numbers I have available:   JTWC's depression number, the 
  JMA-assigned name (if any), JMA's tropical storm numeric designator,
  and PAGASA's name for systems forming in or passing through their
  area of warning responsibility.

                Northwest Pacific Tropical Activity for June

     As the month of June opened, Typhoon Nakri/Enteng was still stirring
  waters south of Japan.  Nakri had peaked at 125 kts (105 kts per JMA)
  on 29 May and had subsequently weakened to minimal typhoon strength,
  but re-intensified to 80 kts on 2 June.  However, this second flowering
  was short-lived and Nakri weakened later that day and became extra-
  tropical on the 3rd.  The extratropical remnants continued moving east-
  northeastward across the North Pacific for another week.  The report on
  Typhoon Nakri/Enteng may be found in the May summary.

     The only other tropical cyclone in Western Pacific waters during June
  was the deadly and destructive Typhoon Fengshen/Frank.  More than 1000
  lives were lost in the Philippines, including several hundred who drowned
  when a ferry capsized during the storm.  A report on Fengshen/Frank

                             TYPHOON FENGSHEN
                        (TC-07W / TY 0806 / FRANK)
                               17 - 27 June

  Fengshen: contributed by China, means 'God of wind' in Chinese

  A. Introduction

     Typhoon Fengshen was a late June typhoon of moderate intensity which
  slashed destructively through the Philippines where it was known as
  Typhoon Frank.  The storm left a trail of death and destruction as it
  passed through the archipelago.  According to the Wikipedia report,
  there were 1356 fatalities directly attributable to Fengshen/Frank
  with 41 others missing.  Total damage is estimated at US$480 million.
  The storm also caused minor damage in Hong Kong, Macau, and southern
  China.  Over 700 of the fatalities occurred when a ferry, the MV Princess
  of the Stars, capsized near Sibuyan Island as the typhoon roared by.

  B. Synoptic History

     The JMA identified a developing tropical disturbance several hundred
  miles east of Mindanao as a weak tropical depression on 17 June.  JTWC
  issued their first warning on Tropical Depression 07W at 1200 UTC on
  the 18th, locating the system approximately 155 nm northwest of Palau.
  PAGASA designated the system as Tropical Depression Frank, and JTWC
  upgraded TD-07W to tropical storm status on the second warning, issued
  at 18/1800 UTC.  At 0000 UTC 19 June, JMA upped the intensity to 35 kts
  and assigned the international name Fengshen.  Fengshen/Frank embarked
  on a west-northwesterly track toward the Philippines and quickly reached
  typhoon status, being upgraded by both JTWC and JMA at 19/1800 UTC.
  The storm struck Samar Island with an intensity of 75 kts early on the
  20th and continued to intensify as it moved through the archipelago.
  Peak intensity of 95 kts (90 kts 10-min avg per JMA) and a CP of 945 mb
  was reached at 21/0000 UTC while the typhoon was centered over the
  Visayan Sea near 11.8N/122.3E.

     Shortly after reaching peak intensity Fengshen/Frank turned to a
  northwesterly track as high pressure to the north weakened.  The storm
  passed very near Manila around 22/0000 UTC with the MSW estimated at
  70-75 kts.   Continuing northwestward across western Luzon, the system
  weakened into a tropical storm and had moved out over the South China
  Sea by 23/0000 UTC.   Tropical Storm Fengshen maintained an intensity
  of 50-55 kts while traversing the South China Sea and made landfall
  in China near Shenzhen, Guangdong Province, around 2200 UTC on 24 June.
  Fengshen had weakened into a tropical depression by late on the 25th
  with JTWC and JMA issuing their final warnings at 25/1200 and 25/1800
  UTC, respectively.  The weakening remnants of Fengshen continued north-
  ward across China for a couple more days before dissipating.

  following URL:>

  at the following link:>

  C. Forecast Track Errors

     Forecast track errors were abysmal with Typhoon Fengshen.  The 
  model consensus consistently carried the cyclone north, initially even
  well east of the Philippines.  And even after the system had emerged
  into the South China Sea, the model forecast tracks were converging on
  Taiwan.  Only the UKMET model and perhaps one other correctly forecast
  the landfall in south China well to the west of where the other models
  were insisting that Fengshen would go.   Initially a strong ridge was
  located north of the developing system, and the models kept breaking
  down the ridge and weakening it.  This obviously didn't happen. 
     Following are some comments from Roger Edson regarding Fengshen's 
  track and the forecast errors (slightly edited):

  (1) East of the Philippines:  As Fengshen developed, it had been going
      WNW for several days.  I don't think the models realized how strong
      the ridge was to the north, and kept breaking it down and moving the
      TC (or its remnants) northward and east of Taiwan.  (Most models
      could not even hold onto the circulation, however.)

  (2) Within the Philippines:  Here the TC continued to rapidly intensify
      in spite of hopping over the various islands (not unusual for TCs in
      this area), and then made an almost 90-degree turn to the right
      (north) as if it were going to finally follow the recurve forecast.
      This abrupt turn was also unusual as I would usually expect it to
      continue through the islands into the South China Sea before
      recurving.  Anyway, this was the time (maybe the only time during
      its life cycle) when the vertical extent of the TC was fully
      developed and the pressure tendency was toward the north, and it
      actually followed the mean tropospheric steering flow...and the
      model forecasts.

  (3) In the South China Sea:  Thanks to a combination of strong north-
      easterly shear and some dry air to the north, the TC came out of
      the Philippines...and a 'half typhoon'---seemed like it
      was almost fully developed in the southern half of the circulation,
      and had hardly any deep convection (except for some brief periods
      of time over its center) over its northern half.  Clearly, the
      various model forecasts did not take into consideration (or
      physically incorporate) this strong upper-level flow (above 400 mb).
      This seems to be something the forecaster always sees, especially
      in the water vapor imagery, but the models never seem to understand.
      (Similarly, we see this all the time with TUTT interaction).
      Normally, one would not forecast a TC to move directly into the
      shear!  In addition, when the TC is not fully developed in the
      vertical, the models have a problem with identifying the 'apparent'
      steering flow as I don't think the vortex and the environmental
      interaction is accurately modeled.

  NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea

  Activity for June:  2 depressions

                North Indian Ocean Tropical Activity for June

     No officially recognized tropical cyclones formed in the North Indian
  Ocean basin during June, but there were a couple of depressions.  The
  first formed in the Arabian Sea near 15.5N/66.0E at 0000 UTC 5 June. 
  This system moved generally northwestward over the next couple of days.
  I did prepare a track for this system in the June edition of the global
  tracks file.  SAB assigned an intensity of T2.5/2.5 at 06/0230 UTC, but
  I left the MSW at 30 kts since neither JTWC nor IMD indicated tropical
  storm intensity.  However, there were some opinions expressed via e-mail
  that the system was a weak tropical storm, based in part on some ASCAT
  data which showed 30-kt winds all the way around the depression.  The
  system had weakened significantly by 7 June and the final track point
  was near 20.8N/62.8E at 07/0600 UTC.

     Another system in the Bay of Bengal was identified as a tropical
  depression by IMD.  The low-pressure area had become a depression by 
  16 June and was centered at 0300 UTC near 21.5N/90.0E, or about 120 nm
  southeast of Kolkata (Calcutta).  The depression subsequently moved
  northward and crossed the Bangladesh coastline between 16/1100 and 1200
  UTC, and at 1200 UTC was centered over coastal Bangladesh near 
  22.0N/89.5E, or about 70 nm east-southeast of Kolkata.  The system was
  forecast to continue further inland and weaken.  No track was included
  for this depression in the companion cyclone tracks file.


  SOUTHWEST INDIAN OCEAN (SWI) - South Indian Ocean West of Longitude 90E

  Activity for June:  No tropical cyclones


  Activity for June:  No tropical cyclones


  Activity for June:  No tropical cyclones


  SOUTH PACIFIC (SPA) - South Pacific Ocean East of Longitude 160E

  Activity for June:  No tropical cyclones


     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:>

     Information regarding how to interpret the coded reconnaissance
  messages may be found at the following URL:>

  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:>

  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:>

  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:>>

  On the NRL site, the link to past years can be found in the upper left 
  corner of the screen.  For the CIMSS site, a link to data archives is 
  located in the lower left portion of the screen.

     Additional tropical satellite imagery, along with looping ability for
  composite microwave imagery for the Western Hemisphere north of the
  equator, can be found at:

  (1) For the Eastern North Pacific:>

  (2) For the Atlantic, Gulf of Mexico and Caribbean Sea:>

  (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:>

     Steve Young has compiled many of these tracks onto a single webpage
  which is very user-friendly:>

     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

  Chris Landsea):>>>>

     Another website where much information about tropical cyclones may
  be found is the website for the UK Meteorological Office.  Their site
  contains a lot of statistical information about tropical cyclones
  globally on a monthly basis.  The URL is:>


     JTWC now has available on its website the Annual Tropical Cyclone
  Report (ATCR) for 2007 (2006-2007 season for the Southern Hemisphere).
  ATCRs for earlier years are available also.

     Also, TPC/NHC has available on its webpage nice "technicolor"
  tracking charts for the 2007 Atlantic and Eastern North Pacific
  tropical cyclones; also, storm reports for all the 2007 Atlantic
  and Eastern North Pacific cyclones are now available, as well as
  track charts and reports on storms from earlier years.
