address any comments or questions to be...@hrd-tardis.nhc.noaa.gov (assuming
the mailer stays operational!)
Author's second note: I will be out of town at Forecaster's Development
School and a vacation for the next month. Dave Roth will write the summary
for me while I'm away.
Special Announcement: A digitized version of the weekly summary with DMSP
polar orbiting satellite imagery is now available via the World Wide Web (http
protocol) using Mosaic. This is courtesy of Greg Deuel at the DMSP satellite
archive. It can be retrieved by:
1. Open the Open URL window (under File) in Mosaic, then typing:
http://web.ngdc.noaa.gov.
2. Find the Home Page for the DMSP satellite archive
3. Click on Weekly Updated Items, then click on the dates given on the next
page.
4. The imagery links will be color-coded inside the summary text.
There will generally be a 1-2 day lag from the time I mail the summary until
the digitized version is ready. For more information on the imagery, as well as
for how the digitized summary and images can be retrieved by ftp, gopher, etc.,
please contact Greg Deuel (Internet: g...@po-box.ngdc.noaa.gov).
Intermin author's note: Yes, once again this is David Roth giving you the
scoop on the tropics. Like before, if you hear or know of anyone that gets
the summary, yet isn't receiving it, mail me at ro...@huey.met.fsu.edu and this
will be remedied immediately! This time I'll try to get it posted to vnews
in a more timely fashion! If you have any info for the summaries yourselves,

WEEKLY TROPICAL CYCLONE SUMMARY #143 APRIL 24 - MAY 01, 1994
North Atlantic Basin: No tropical cyclones.
Eastern North Pacific Basin (E of 140 Deg. W): No tropical cyclones.
Central North Pacific Basin (180 Deg. W to 140 Deg. W): No tropical cyclones.
Western North Pacific Basin (W of 180 Deg. W): No tropical cyclones.
North Indian Ocean Basin: One tropical cyclone.
Tropical Cyclone 2B (or not 2B!): A large disturbance in the Bay of Bengal
was organizing near 9N on the 28th. By 0000Z on the 29th, it had become organ-
ized enough for Guam to start issuing advisories on it as TC 2B. 2B moved
northward through the entire summary period, while gaining strength all the
while. During its initial slow increase in strength on the 29th, it meandered
at 5 kts near 11N 90.5E. This allowed the cyclone to feed off the warm waters
of the Bay of Bengal, which was a notorious breeder of the most deadly of
cyclone in recent memory, the Bangladesh Cyclone of 1985. By the end of the
summary period, maximum sustained winds had increased to 100 knots near 18.5N
91.5E, and 2B was progged to hit Bangladesh as a strong typhoon, while
continuing its trek northward at 5 to 10 knots.
South Indian Ocean Basin (W of 135 Deg. E): One tropical cyclone.
Tropical Cyclone 30S (Willy): Willy developed in the open south Indian
ocean at 0600z on the 29th near 10S 95E. Motion was south southeast through
its entire lifetime. Maximum sustained winds never exceeded 35 knots. After
24 hours of life in the tropics, Willy was freed of its existence near 13S
96E, another senseless casualty of vertical wind shear.
South Pacific Ocean Basin (E of 135 Deg. E): Two tropical cyclones.
Tropical Cyclone 29P: Guam began writing advisories on this cyclone at
0000z on the 24th near 14.5S 160.5E. This cyclone... with maximum winds
during its lifetime never exceeding 35 knots... almost immediately began
experiencing vertical wind shear. The system became well exposed... removed
from its deep convection... and weakened into a low pressure area 24 hours
after its birth. It drifted slowly eastward during its short stint as a
tropical cyclone and dissipated near 15S 159.5E.

over. Please address any questions or comments on the information for the
next few weeks to David Roth at Internet address:
