WEEKLY TROPICAL CYCLONE SUMMARY #108: AUGUST 22 - 29, 1993
North Atlantic Basin:
Hurricane Emily: Tropical Depression Five formed near 20N 53W on 22 Aug-
gust. Initially moving west, the system turned west-northwest on 23 August
and north-northwest on 24 August. The depression slowed to a north-northwest
drift on 25 August, then it turned west the next day as strengthened to both
tropical storm and hurricane intensity. While the minimum presure reported
by reconaissance aircraft at this time was only 1005 mb, the ship OMI Mis-
souri passed near the center at 1100 UTC and reported 65 kt winds. Emily
weakened back to tropical storm intensity on 27 August as it moved west, then
it regained hurricane status the next day as it turned northwest. A first
peak intensity of 75 kt was reached later that day. Emily turned north-
northwest on 29 August, and at the end of the summary period it was con-
tinuing that track with 70 kt winds. The next summary will have a description
of Emily's brush with the North Carolina coast.
Tropical Storm Dennis: Tropical Depression Six formed near 13N 31W on 23
August. The system initially moved west-northwest, and this motion was main-
tained through 26 August. The system reached tropical storm strength on 24
August and a peak intensity of 45 kt on 25 August. Dennis turned north-
northwest on 27 August as it weakened to a depression, and it dissipated the
next day 22N 45W.
Eastern North Pacific Basin (E of 140 Deg. W):
Hurricane Greg: At the start of the summary period, Greg was moving west
with 80 kt winds. Greg turned west-northwest on 23 August then back to the
west the next day while maintaining 75 kt sustained winds. The storm turned
west-southwest on 25 August and back to west-northwest the following day as
it weakened to a tropical storm. Greg continued west northwest on 27 August,
then it turned west on 28 August as it weakened to a tropical depression.
The system crossed into the Central North Pacific later that day with 30 kt
winds. Although the storm crossed Socorro Island, there are no reports of
damage or casualties at this time.
Hurricane Hilary: At the start of the summary period, Hilary was quasi-
stationary near 20N 111W with 70 kt winds. The system moved west-northwest
and then north on 23 August as it weakened to a tropical storm. Hilary moved
north-northwest on 24 August as it weakened to a minimal tropical storm.
Later that day, winds increased to 50 kt, and this intensity was maintained
on 25 August as Hilary moved north into the Baja California peninsula. Hilary
continued north across the Gulf of California into Mexico and weakened to a
tropical depression on 26 August, and the system dissipated the next day over
northwest Mexico. There are no reports of damage or casualties at this time.
Tropical Storm Jova: Tropical Depression 11E formed near 14N 97w on 29
August. Moving west-northwest, it became Tropical Storm Jova later that day.
At the end of the summary period, Jova was moving west-northwest with 35 kt
winds.
Central North Pacific Basin (180 Deg. W to 140 Deg. W):
Tropical Depression Greg: Ex-hurricane Greg entered the Central Pacific on
28 August moving west with 30 kt winds. The system dissipated later the same
day near 21N 141W.
Western North Pacific Basin (W of 180 Deg. W):
Typhoon Keoni: At the start of the summary period, Keoni was moving north-
northwest with 75 kt winds. Keoni turned west on 23 August while slowly
weakening, then the storm turned northwest the next day as winds increased to
85 kt. Keoni turned back to the west-northwest on 25 August while weakening
again, and a turn to the north followed the next day as it weakened to a
tropical storm. A turn to the northeast took place on 27 August, followed by
east-southeast motion the next day as Keoni weakened to a tropical depres-
sion. The system weakened further to a low pressure area on 29 August near
37N 163E. While this was the end of Keoni as a tropical cyclone, the remnant
low is still being tracked in case it tries to re-develop.
Typhoon Vernon: At the start of the summary period, Vernon was moving
north-northwest with 40 kt winds. Vernon followed a general northwest track
on 23-25 August, with the system reaching typhoon intensity on 24 August and
a peak intensity of 85 kt on 25 August. The storm turned north on 26 August
while weakening. Vernon crossed over eastern Japan east of Tokyo on 27 Aug-
ust within winds estimated at 70 kt. Choshi reported a minimum pressure of
972.8 mb at 0600 UTC, while Narita airport near Tokyo reported peak gusts of
53 kt west of the center at 0330 UTC. Vernon continued north-northeast and
became extratropical over the island of Hokkaido the next day. There are no
reports of damage or casualties at this time.
Tropical Storm Winona: Tropical Deprssion 18W formed over the southern
Philippine Islands near 12N 125E on 22 August. Initially moving west, the
system turned west-northwest on 23 August as it reached tropical storm in-
tensity. Winona turned north-northwest on 24 August as its maximum winds
reached a peak of 45 kt, and the motion continued the next day. Winona turned
northwest on 26 August and west on 27 August while maintaining 40-45 kt
winds. The storm continued west into Vietnam with 40 kt winds late on 28 Aug-
ust, and it dissipated over land the next day. There are no reports of damage
or casualties at this time.
Tropical Depression: A tropical depression formed near 16N 143E on 23
August. It moved erratcially before dissipating near 17N 144E on 25 August.
Maximum winds in this short-lived system were estimated at 30 kt.
Tropical Depression 19W: Tropical Depression 19W formed near 20N 137E on
29 August. At the end of the summary period, it was moving west with 30 kt
winds.
North Indian Ocean Basin: No tropical cyclones.
South Indian Ocean Basin (W of 135 Deg. E): No tropical cyclones.
South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
