GLOBAL TROPICAL CYCLONE TRACKS - APRIL 2007
!!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!!

NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180
Sources of Information
----------------------
The track coordinates and 1-minute average maximum sustained wind
values in general were taken from operational warnings issued by the
Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
located at Pearl Harbor, Hawaii. The central pressure and 10-minute
average maximum sustained wind estimates for most systems were obtained
from warnings issued by the Japanese Meteorological Agency (JMA), which
is the World Meteorological Organization's Regional Specialised Meteor-
ological Centre for the basin. In a few instances, information from
warnings issued by other Asian warning centers may have been utilized.
The center position coordinates from JMA and other centers were com-
pared with those from JTWC and annotations made in the Remarks column
when the differences in general amounted to 40-50 nm or more.
Michael V. Padua of Naga City in the Philippines, owner of the
Typhoon 2000 website, sends me cyclone tracks based upon warnings
issued by the Japanese Meteorological Agency and the Philippines'
Atmospheric, Geophysical & Astronomical Services Administration
(PAGASA). A special thanks to Michael for his efforts.

SOUTHWEST INDIAN OCEAN (SWI) - South Indian Ocean West of Longitude 90E
Sources of Information
----------------------
The track coordinates as well as the central pressure and 10-minute
average maximum sustained wind estimates were obtained from warnings
issued by Meteo France's Tropical Cyclone Warning Centre on Reunion
Island (MFR), which is the World Meteorological Organization's Regional
Specialised Meteorological Centre for the basin. The 1-minute average
maximum sustained wind estimates were taken from warnings issued by the
Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
located at Pearl Harbor, Hawaii. The center position coordinates from
JTWC were compared with those from MFR and annotations made in the
Remarks column when the differences in general amounted to 40-50 nm
or more.

Note: Only four warnings were issued on this system by MFR. However, on
that agency's website, a table of the date, time, coordinates and classi-
fication were available, and the above track is based on this. Prior to
11/1200 UTC all the MSW estimates are my own, based on the assigned
classification category, which is annotated in the Remarks column. Given
the date and location of formation, there was some question if this
system could be a re-incarnation of former TC Jaya, but according to
Philippe Caroff, based on their analysis, this does not appear to be the
case.

SOUTH PACIFIC (SPA) - South Pacific Ocean East of Longitude 160E
Sources of Information
----------------------
The track coordinates as well as the central pressure and 10-minute
average maximum sustained wind estimates were obtained from warnings
issued by the Tropical Cyclone Warning Centres at Nadi, Fiji, and
Wellington, New Zealand. The 1-minute average maximum sustained wind
estimates were taken from warnings issued by the Joint Typhoon Warning
Center (JTWC) of the U. S. Air Force and Navy, located at Pearl Harbor,
Hawaii. The center position coordinates from JTWC were compared with
those from the Southern Hemisphere centres and annotations made in the
Remarks column when the differences in general amounted to 40-50 nm
or more.

!!!!!! IMPORTANT NOTE - PLEASE READ !!!!!!
To repeat the caveat which is included in the Author's Note
at the end of the cyclone summaries--the tropical cyclone tracks
I prepare are based upon the operational warnings/advisories/
advices/bulletins which are issued by the various tropical cyclone
warning agencies around the world. Users of these tracks should
be aware that they are preliminary and subject to revision during
post-seasonal analyses of the cyclones by the forecasters and
analysts at the several warning centers.
For the Atlantic and Northeast Pacific basins, official tropical
cyclone reports and "best tracks" can be found at the website of
the Tropical Prediction Center/National Hurricane Center:
http://www.nhc.noaa.gov>
The Joint Typhoon Warning Center's website contains links to their
Annual Tropical Cyclone Reports which include that agency's "best
tracks" for tropical cyclones in the Northwest Pacific basin, the
North Indian Ocean, and the Southern Hemisphere:
https://metocph.nmci.navy.mil/jtwc.php>
SPECIAL NOTE: Back issues of the global tropical cyclone summaries
and monthly cyclone track files can be obtained at the following
