WEEKLY TROPICAL CYCLONE SUMMARY #106: AUGUST 8 - 15, 1993
North Atlantic Basin:
Tropical Storm Bret: At the start of the summary period, Bret was near the
Venezuela-Colombia border moving west with 40 kt winds. Bret moved into the
southwest Caribbean as it weakened to a tropical depression on 9 August. Bret
regained tropical storm status on 10 August and reached an intensity of 40 kt
as it moved into southern Nicaragua. The system continued west-northwest and
weakened to a depression later that day. Bret was then designated Tropical
Depression 8E as it approached the Pacific. This system affected the Caribbean
islands along the coast of South America, Venezuela, Colombia, and Nicaragua.
So far, anywhere from 95 to 150 people have been reported killed in Venezuela
due to mudslides near Caracas. One person has been reported killed in Colombia.
Thirteen people have been reported killed in Nicaragua and nearby offshore
islands with thousands reported homeless.
Tropical Storm Cindy: Tropical Depression 4 formed near 15N 61W (just east
of Martinique in the Windward Islands) on 14 August. Moving west-northwest,
the system reached tropical storm intensity later that day. Cindy continued
west-northwest on 15 August, and at the end of the summary period it was south
of Puerto Rico moving west-northwest with 35 kt winds. Up to this time, Cindy
has been a poorly organized system with a minimum pressure measured by re-
connaisance aircraft of 1010 mb. So far, Cindy has affected the Leeward and
Windward Islands. Heavy rains on Martinique caused flooding and mudslides that
killed two people.
Eastern North Pacific Basin (E of 140 Deg. W):
Hurricane Fernanda: Tropical Depression 7E formed on 9 August near 13N 108W.
Moving west, the system became Tropical Storm Fernanda later that day. The
storm continued west through 11 August as it reached hurricane intensity on
10 August and a peak intensity of 125 kt on 11 August. Fernanda turned west-
northwest on 12 August, then back to the west on 13 August. Slow weakening
prevailed during this time, and when Fernanda moved west into the Central
North Pacific on 14 August it was packing 90 kt winds.
Tropical Storm Greg: Atlantic Tropical Depression Bret was designated
Pacific Tropical Depression 8E on 10 August while over Nicaragua. The system
moved west-northwest and never really emerged over open water before it weak-
ened to a broad low pressure area near 13N 89W on 11 August. The remains of
the system continued westward and re-developed into a tropical depression near
15N 103W on 15 August. Moving west-northwest, the depression reached tropical
storm intensity later that day. At the end of the summary period, Greg was
moving west-northwest with 50 kt winds.
Central North Pacific Basin (180 Deg. W to 140 Deg. W):
Hurricane Fernanda: Hurricane Fernanda entered the Central North Pacific on
14 August moving west with 90 kt winds. It weakened to an intensity of 75 kt
later that day, then re-intensified to 90 kt maximum winds on 15 August as it
turned west-northwest. At the end of the summary period, Fernanda was east of
the island of Hawaii moving west-northwest with 90 kt winds.
Hurricane Keoni: Tropical Depression 1C formed near 12N 144W on 9 August.
Initially drifting west, the system became quasi-stationary the nex day near
12N 145W. TD-1C resumed a westward drift on 11 August, and a faster westward
track was established on 12 August as the system reached tropical storm
intensity. Keoni continued a general west track through the end of the sum-
mary period while steadily intensifying. It reached hurricane intensity on 14
August, and faster intensification followed on 15 August. At the end of the
summary period, Keoni was southeast of Johnston Island with 90 kt winds. Ship
OWUO6 reported 32 knot sustained winds and a pressure of 1005.5 mb at 0300 UTC
9 August as Keoni was first developing. A reconaissance plane reported a cen-
tral pressure of 956 mb and flight level winds (10,000 ft) of 118 kt at 1943
UTC 15 August.
Western North Pacific Basin (W of 180 Deg. W):
Typhoon Robyn: At the start of the summary period, Robyn was moving north-
northeast toward the Japanese island of Kyushu with 110 kt winds. Robyn moved
across Kyushu and the islands to the south on 9 August with 90-100 kt sustained
winds, and the storm moved into the Sea of Japan later that day while weak-
ening. Robyn continued northeast through the Sea of Japan on 10 August as it
weakened to a tropical storm, and the system became extratropical near 42N 139E
on 11 August. This system affected much of southwestern Japan. Naze reported a
minimum pressure of 953.5 mb at 0300 UTC 9 August, and Kagoshima reported a
954 mb pressure at 2000 UTC the same day. Amami-O-Shima reported gusts above
80 kt between 0600-0900 UTC 9 August. Nagasaki reported 54 kt sustained winds
with gusts to 78 kt at 2000 UTC 9 August, while Kanoya checked in with an 80
kt gust at 1528 UTC the same day. There are no reports of damage or casualties
at this time.
Typhoon Steve: At the start of the summary period, Tropical Storm Steve was
moving west across the Philippine Sea with 60 kt winds. Steve turned west-
northwest on 9 August, and this general motion continued the next day as it
reached a peak intensity of 70 kt. Steve turned nothwest on 11 August and
weakend to a tropical storm due to strong upper level shearing. Steve
continued northwest the next day as it weakened to a depression. It turned
west-northwest on 13 August and continued this track until it dissipated near
16N 125E on 14 August. Although Steve affected the Marianas Islands as a
tropical storm, there are no reports of damage or casualties at this time.
Tropical Depression 15W: Tropical Depression 15W formed near 8N 177E on 13
August. moving generally west-northwest, the system dissipated the next day
near 10N 172E. Maximum winds in this short-lived system were estimated at 30
kt.
Tropical Depression 16W: Tropical Depression 16W formed near 8N 132E on 15
August. At the end of the summary period it was moving northwest with 25 kt
winds.
Special Western Pacific Update:
Tropical Storm Ofelia and Typhoon Percy (Summaries #103-104): The Weekly
Climate Bulletin reports that over 19.7 in (500 mm) of rain fell on parts of
Kyushu primarily due to the two storms. Ensuing landslides have claimed at
least 12 lives.
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.
