WEEKLY TROPICAL CYCLONE SUMMARY #61: SEPTEMBER 27 - OCTOBER 4, 1992
North Atlantic Basin:
Tropical Storm Bonnie: Ex-hurricane Bonnie had converted to an extratrop-
ical low near 33N 44W on 27 September. Then, central convection redeveloped,
and the system regained tropical storm status near 35N 40W on 28 September. At
this time, the rejuvenated Bonnie reached an intensity of 60 kt based on a re-
port from ship OUUR5, which had 60 kt winds and a pressure of 1002 mb. Bonnie
moved on an east-noertheast track while slowly weakening, and it moved through
the Azores Islands on 30 September before becoming extratropical once again
near 39N 23W. Lajes Air Base on Tereciera reported a mimimum pressure of 996.7
mb, while Santa Maria Island reported 33 kt sustained winds. There are no re-
ports of damage or casualties at this time.
Tropical Depression Seven: At the start of the summary period, Tropical De-
pression Seven was moving west-northwest with 30 kt winds. The system turned
north on 28 September and continued this track until the system weakened to
a low pressure area on 1 October near 28N 42W. Maximum winds in this poorly
organized system were 30 kt.
Tropical Storm Earl: At the start of the summary period, Tropical Depres-
sion Eight was moving west-northwest with 30 kt winds. The system turned north-
west the next day as it approached the Florida coast, then it stalled near 30N
79W on 29 September. The system turned east on 30 September as it finally
reached tropical storm intensity. Earl continued continued an almost due east
track until it became extratropical near 29N 63W on 3 October. Maximum winds
reached 50 kt on 1 October with a minimum pressure measured by reconnaissance
aircraft of 990 mb. Although Earl affected parts of the Florida coast during
its early stages, there are no reportrs of damage or casualties at this time.
Eastern North Pacific Basin (E of 140 Deg. W):
Hurricane Tina: At the start of the summary period, Tina was moving south-
west with 95 kt winds. Tina turned west-southwest on 28 September and west on
29 September as it continued to intensify. A NOAA research plane flew into the
storm on 29 September and measured a minimum central pressure of 944 mb along
with flight-level winds of 125 kt. Tina continued west and reached a peak
intensity of 130 kt on 1 October. Tina continued westward through 2 October
while weakening. The storm turned northwest on 3 October, and it continued
this track through the end of the summary period. Tina dropped below hurri-
cane intensity on 4 October, and at the end of the summary period it was pack-
ing 50 kt winds.
Hurricane Virgil: Tropical Depression 23E formed near 14N 101W on 1 Oct-
ober. Moving northwest, the system reached tropical storm intensity later that
day. Rapid strengthening then ensued, with Virgil reaching hurricane strength
the next day and a peak intensity of 115 kt on 3 October. Virgil drifted in an
erratic north-northwest fashion until it slammed into the coast of Mexico east
of Manzanillo with 105 kt winds on 4 October. At the end of the summary period,
Virgil was over Mexico with winds of only 30 kt. Thus far, there are no reports
of damage or casualties.
Central North Pacific Basin (180 Deg. W to 140 Deg. W):
Tropical Storm Roslyn: At the start of the summary period, ex-hurricane
Roslyn was drifting west with 35 kt winds. Roslyn stalled near 19N 150W on 28
September, then drifted east-northeast on 29 September while maintaining 35
kt winds. Roslyn weakened to a depression on 30 September, and it dissipated
as a tropical cyclone later that same day near 22N 147W. The remains of Roslyn
were trackable for several more days as they drifted northwest northeast of the
Hawaiian Islands.
Western North Pacific Basin (W of 180 Deg. W):
Typhoon Ward: At the start of the summary period, Tropical Storm Ward was
moving west-northwest with 45 kt winds. Ward moved slowly northwest on 28
September, then it turned north on 29 September as it reached typhoon inten-
sity. Ward turned northwestward on 30 September and west on 1 October. It
then moved west-southwest on 2 October as it reached a peak intensity of 100
kt. Ward turned back to the northwest on 3 October, and it moved northward
once again on 4 October. At the end of the summary period, Ward was moving
north with 85 kt winds.
North Indian Ocean Basin:
Tropical Cyclone 06A formed in the Arabian Sea near 17N 67E on 1 October.
Initially moving west-northwest, the storm turned west as it reached a peak
intensity of 50 kt on 2 October. TC-06A moved inland over Oman just south of
Masirah early on 3 October and dissipated over land later that day. Masirah
reported a peak gust of 33 kt with a minimum pressure of 1004 mb. There are
no reports of damage or casualties at this time.
South Indian Ocean Basin (W of 135 Deg. E):
Tropical Cyclone Aviona (TC-01S): Tropical Cyclone Aviona formed near 9S
89E on 27 September. Initially moving westward, the storm turned southwest as
it reached a peak intensity of 65 kt the next day. Aviona continued southwest
on 29 September, then it gradually turned west-southwest while weakening on
30 September. Aviona continued a general west-southwest motion through the rest
of the summary period. The system continued to weaken, and by the end of the
summary period winds were down to 30 kt.
South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
