WEEKLY TROPICAL CYCLONE SUMMARY #60: SEPTEMBER 20 - 27, 1992
North Atlantic Basin:
Hurricane Bonnie: At the beginning of the summary period, Bonnie was
tracking north-northeast with 75 kt winds. Bonnie continued this course un-
til 21 September, when the storm turned east and reached a peak intensity of
90 kt. Bonnie became quasi-stationary near 38N 51W the next day, and it stayed
in this vicinity through 23 September. Bonnie maintained its 90 kt winds dur-
ing this time, but it quickly weakened to tropical storm intensity on 24 Sep-
tember as it started drifiting southwest. Bonnie turned south on 25 September
and east on 26 September. The system briefly weakened to a depression on 26
September, only to regain minimal tropical storm intensity later that day as
the convection flared up. Bonnie became extratropical near 33N 44W on 27 Sep-
tember.
Hurricane Charley: Tropical Depression Five formed near 30N 33W on 21 Sep-
tember. Initially quasi-stationary, the system started moving north-northwest
the next day as it reached tropical storm intensity. Charley continued it
north-northwest track on 23 September as it reached hurricane intensity, then
it turned northeast the next day as it reached a peak intensity of 95 kt. On
25 September, Charley became quasi-stationary near 36N 33W as it slowly weak-
ened. The hurricane continued to weaken as it started moving east-northeast
on 26 September, and it was downgraded to a tropical storm just before passing
through the Azores Is. on 27 September. Charley became extratropical later
that day near 42N 23W. Lajes Air Base in the Azores reported sustained winds
of 46 kt gusting to 71 kt just after the center passed, with a minimum pres-
sure of 982 mb during the center passage. There are no reports of damage or
casualties at this time.
Tropical Storm Danielle: Tropical Depression Six formed near 33N 75W on
22 September. Moving northeast, it reached tropical storm intensity later that
day. Danielle stalled near 35N 74W on 23 September, then drifted west on 24
September. Danielle turned abruptly north on 25 September, passing just east of
Cape Hatteras, NC and making landfall near Wallops Island, VA. During the
northward track, the minimum central pressure measured by reconaissance air-
craft dropped to 1001 mb and maximum winds reached a peak of 55 kt. Danielle
continued north to north-northwest after landfall and dissipated the next day
over eastern Pennsylvania. Maximum reported surface winds were 44 kt at the
Chesapeake Bay automated station. Tropical storm force gusts affected the area
from the North Carolina Outer Banks to the Virginia Eastern Shore. Some houses
have been reported destroyed by beach erosion in North Carolina. There is a
press report that one person was killed in a sailboat off the New Jersey coast.
Tropical Depression Seven: Tropical Depression Seven formed on 25 September
near 11N 37W. Initially moving west, the system turned west-northwest the next
day. This track continued to the end of the summary period. This system has
spent all of its life in a strong shearing environment, and maximum winds in
the system thus far are 30 kt.
Tropical Depression Eight: Tropical Depression Eight formed near 26N 70W
on 26 September. Initially tracking westward, the system turned west-northwest
on 27 September and maintained this motion until the end of the summary period.
Maximum winds thus far are 30 kt with a minimum central pressure measured by
reconaissance aircraft of 1002 mb.
Eastern North Pacific Basin (E of 140 Deg. W):
Hurricane Roslyn: At the start of the summary period, Roslyn was moving
west with 45 kt winds. Roslyn continued to move west until it entered the
Central Pacific on 24 September. Roslyn reached hurricane intensity on 22
September, and a peak intensity of 85 kt was reached the next day. Weakening
followed, and when Roslyn crossed into the Central Pacific it had 65 kt winds.
Hurricane Seymour: At the start of the summary period, Seymour was moving
northwest with 70 kt winds. This turned out to be the peak intensity of the
storm. Seymour turned west-northwest on 21 September and weakened to a tropical
storm. Seymour then turned west the next day and regained mimimal hurricane
intensity. The storm maintained this track and intensity through 23 September,
then it turned west-southwest and weakened to a tropical storm again on 24 Sep-
tember. Seymour moved southwest on 25 September, and it turned west the next
day as it weakened to a depression. The system turned north-northwest on
27 September before dissipating later that day near 25N 129W.
Hurricane Tina: At the start of the summary period, Tina was moving west
with 65 kt. Tina continued west on 21 September as it reached a first peak in-
tensity of 75 kt. Tina's westward motion slowed to an erratic dirft the next
day as it slowly weakened. Tina re-intensified to 75 kt intensity on 23 Sep-
tember as it continued drifiting slowly west. Tina turned north on 24 Septem-
ber as it weakened to mimimal hurricane strength, and it moved north-northeast
the next day as it weakened to a tropical storm. Tina turned back to a westerly
track on 26 September as it regained hurricane intensity. Tina then turned
southwest on 27 September, and at the end of the summary period it was contin-
uing this track with winds of 95 kt.
Central North Pacific Basin (180 Deg. W to 140 Deg. W):
Hurricane Roslyn: Roslyn crossed into the Central North Pacific with 65 kt
winds on 24 September. Roslyn continued west through the rest of the summary
period, although the motion had slowed to a drift by the end of the period.
Hurricane intensity was maintained through 25 September, with Roslyn weakening
to a tropical storm the next day. At the end of the summary period, Roslyn's
winds had decreased to 35 kt.
Western North Pacific Basin (W of 180 Deg. W):
Typhoon Ted: At the start of the summary period, Ted was moving west-north-
west with 60 kt winds toward Luzon. Ted turned northwest on 21 September and
reached a peak intensity of 65 kt while just north of Luzon. Ted turned north
on 22 September and crossed eastern Taiwan as a tropical storm. Taipei reported
a minimum pressure of 988 mb, but no tropical storm force winds were reported
from the observing stations. Ted continued northward along the Chinese coast
near Shanghai on 23 September, and the system became extratropical near 36N
127E (near Korea). Press reports indicate that three people were killed in the
Philippines due to flooding and mudlsides. There are no reports of damage or
casualties from elsewhere along Ted's track.
Tropical Storm Val: Tropical Depression 20W formed near 13N 160E on 23 Sep-
tember. The system moved northwest initially, then turned north the next day
as it reached tropical storm intensity. Val moved generally northward through
rest of its life, with an acceleration of the forward speed on 26 September.
A peak intensity of 45 kt was reached on 25 September, and Val maintained this
intensity until it became extratropical near 43N 156E on 27 September.
Tropical Storm Ward: Tropical Depression 21W formed near 15N 180W on 26
September out of a persistent area of disturbed weather that originally de-
veloped southwest of Hawaii. Moving generally west-northwest, the system be-
came Tropical Storm Ward the next day. At the end of the summary period, Ward
was moving west-northwest with 45 kt winds.
North Indian Ocean Basin:
Tropical Cyclone 05B: Tropical Cyclone 05B formed near 20N 91E on 22 Sep-
tember. Moving in a generally northwest direction, the system dissipated over
the Indian coast near 22N 88E on 24 September. Maximum winds in this system
were estimated to be 30 kt.
South Indian Ocean Basin (W of 135 Deg. E):
Tropical Cyclone 01S: Tropical Cyclone 01S formed near 9S 89E on 27 Septem-
ber. At the end of the summary period, it was moving west with 35 kt winds.
South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
