WEEKLY TROPICAL CYCLONE SUMMARY #166 OCTOBER 2 - 9, 1994
North Atlantic Basin:
Gulf of Mexico/Atlantic Cyclone: At the start of the summary period, the
hybrid low pressure system was over southeastern Alabama moving east-
northeastward. The low continued east-northeast and moved off the Atlantic
coast near Savannah, Georgia early on 3 October. The rapid east-northeastward
motion continued until the low passed north of Bermuda on 4 October. The
system then turned northeast and lost all tropical characteristics near 37N
54W late that same day.
This low continued to have an unusual structure while over the Atlantic.
Rawinsonde data from Bermuda continued to indicate a mid-tropospheric warm
core, and surface observations suggested that the surface circulation became
more tightly wound up. However, satellite imagery suggested that the system
was merging with a cold front during this period. It thus appears that this
low never fully acquired tropical cyclone characteristics.
The low tracked over or near several Atlantic surface stations. Buoy 41004
reported a minimum pressure of 994.9 mb with sustained winds of 40 kt at 0800
UTC 3 October. An automated station at Frying Pan Shoals (off of the North
Carolina coast) reported 51 kt sustained winds with gusts to 59 kt between
1100-1200 UTC the same day. Bermuda reported a minimum pressure of 997 mb at
0753 UTC 4 October, with sustained winds of 38 kt gusting to 58 kt at 0744
UTC. Based on the available data, the peak intensity of this system is
estimated at 45-50 kt.
In addition to the effects reported in the previous summary, coastal
flooding was also reported along the Mississippi, Alabama, and Florida
Panhandle Gulf coasts. There are no reports of casualties from the southeast-
ern U.S., and there are no reports of damage or casualties from Bermuda.
Eastern North Pacific Basin (E of 140 Deg. W):
Tropical Depression 19E: Tropical Depression 19E formed near 18N 113W on
8 October. It remained almost stationary through the remainder of the summary
period with 30 kt winds. This system has since developed into Hurricane Rosa,
and the next summary will have details on its landfall in Mexico.
Central North Pacific Basin (180 Deg. W to 140 Deg. W): No tropical cyclones.
Western North Pacific Basin (W of 180 Deg. W):
Tropical Depression 31W: At the start of the summary period, TD-31W was
southeast of Japan drifting northwest at its peak intensity of 30 kt. The
depression turned east-northeast on 3 October, and this motion continued the
next day. The cyclone turned back westward on 5 October, and it dissipated
on 6 October near 30N 160E.
Typhoon Seth: Tropical Depression 32W formed near 9N 157E on 2 October.
Seth moved westward on 3 October as it reached tropical storm intensity.
Seth followed a general west-northwest track through 6 October as it passed
south of Guam. Typhoon intensity was achieved on 5 October. Seth turned
northwestward on 7 October as it reached a peak intensity of 120 kt. Seth
turned north-northwest on 8 October, and this motion continued through the
end of the summary period. Seth passed through the southern Ryukyu Islands
on 9 October, and at the end of the summary period it was over the East China
Sea west of the Ryukyus with 85 kt winds.
Seth affected the southern Ryukyu Islands and Taiwan. Pengia Yu, Taiwan
reported 77 kt sustained winds with a pressure of 969.8 mb at 2100 UTC 9
October. Yonagunijima Island, Japan reported a minimum pressure of 961.6 mb
at 1200 UTC the same day, while Ishigakijima Island, Japan reported 61 kt
sustained winds at 1500 UTC the same day. Seth also affected Guam, but it
passed far enough south of the island that there were no reports of signif-
icant winds or pressures. There are no reports of damage or casualties at
this time.
North Indian Ocean Basin:
Tropical Depression: A tropical depression formed over the Bay of Bengal
near 16N 83E on 4 October. This system reached a peak intensity of 30 kt
before it moved inland over India later that day. The depression persisted
over eastern India for several days as it tracked northwest, north, and then
northeast. It finally weakened to a low pressure system near 23N 82E on 8
October. While there are no reports of significant winds, Machilipatnam,
India reported a minimum pressure of 993 mb at 0000 UTC 5 October. There are
no reports of damage or casualties at this time.
South Indian Ocean Basin (W of 135 Deg. E):
Tropical Depression: A tropical depression formed near 9S 52E on 5 October.
The system moved west on 5-6 October, then it turned west-northwest on 7
October. It dissipated later that same day near 6S 44E. Maximum sustained
winds in this system were estimated at 30 kt.
South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
