WEEKLY TROPICAL CYCLONE SUMMARY #79: JANUARY 31 - FEBRUARY 7, 1993
North Atlantic Basin: No tropical cyclones.
Eastern North Pacific Basin (E of 140 Deg. W): No tropical cyclones.
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: A low pressure system near 10N 128E briefly organ-
ized into a tropical depression on 1 February. It weakened to a low pressure
system later that day. Maximum winds in this very short-lived system were
estimated at 30 kt.
North Indian Ocean Basin: No tropical cyclones.
South Indian Ocean Basin (W of 135 Deg. E):
Tropical Cyclone Lena (TC-13S): At the start of the summary period, Lena
was moving east-southeast with 40 kt winds. Lena turned east on 1 February
and continued this course through the next day while maintaining 35-45 kt
winds. Lena then weakened rapidly on 3 February as it started interact with
TC-14P, and it dissipated later that day near 16S 122E.
Tropical Cyclone 14P: At the start of the summary period, the remains of
TC-14P were a large monsoon-type low over northwestern Australia. It reach-
the west coast of Australia near 22S on 4 February and regained tropical
depression status the next day while moving west. Tropical storm intensity
was regained on 6 February as the system reached a second peak intensity of
35 kt. TC-14P weakened to a depression the next day as it moved west, and
at the end of the summary period it was moving in a general westerly dir-
ection with 25 kt winds. While TC-14P apparently caused heavy rains over
parts of northwestern Australia, there are no reports of damage or casu-
alties at this time.
South Pacific Ocean Basin (E of 135 Deg. E):
Tropical Cyclone Lin (TC-15P): At the start of the summary period, Lin
was moving southeast away from Samoa with 55 kt winds. Lin continued south-
east on 1 February as it reached hurricane intensity, with a peak intensity
of 90 kt occurring the next day while the storm continued southeastward.
Lin rapidly weakened to a tropical storm on 4 February as it slowed to a
southeastward drift, then it turned south-southwest on 5 February while
continuing to weaken. Lin dissipated on 6 February near 27S 168W. There
are no reports of damage or casualties at this time.
Tropical Depression: A tropical depression formed near 14S 156W on 31
January. Drifting south-southeast, the system briefly reached a peak in-
tensity of 30 kt on 1 February before weakening to a low pressure system
later that day near 16S 155W.
Tropical Cyclone Oliver (TC-16P): A tropical depression formed near 13S
151E on 3 February. Moving initially south-southwest, the system reached
tropical storm intensity the next day. Oliver drifted southward on 5 Febru-
ary as it reached hurricane intensity. Oliver continued south on 6 February,
then it turned south-southwest the next day while reaching a peak intensity
of 110 kt. Oliver passed near the Lihou Reef automated weather station on
7 February. Maximum sustained wind of 89 kt were reported at 0600 UTC,
while a minimum pressure of 949.4 mb was reported at 0900 UTC. At the end
of the summary period, Oliver was moving south-southwest with 110 kt winds.
Tropical Cyclone Mick (TC-17P): A tropical depression formed near 17S
173W on 5 February. Initially moving south, the system turned west-south-
west later that day as it reached tropical storm strength. Mick continued
moving west-southwest on 6 February as it reached a peak intensity of 45
kt, and it maintained this intensity on 7 February as it turned southwest
and south. Mick passed through the Tonga Island group during 6-7 February.
Vava'u Island reported sustained winds of 35 kt gusting to 50 kt at 0300 UTC
6 February, with a minimum pressure of 996.7 mb three hours later. Lifuka and
Ha'afeva Islands reported 45 kt sustained winds at 2100 UTC the same day.
Ono-I-Lau Island reported a minimum pressure of 993.7 mb at 1800 UTC 7 Feb-
ruary, but maximum reported winds were below 35 kt. At the end of the
summary period, Mick was moving southward southwest of Tonga with 45 kt
winds. There are no reports of damage or casualties at this time.
Tropical Cyclone: A tropical depression formed near 20S 141W on 6 Feb-
ruary. Wind reached tropical storm force later that day as the system moved
erratically southwest. A peak intensity of 40 kt was achieved as the
system turned south on 7 February. At the end of the summary period, the
cyclone was moving south with 35-40 kt winds. As no warning center formally
named this system a tropical storm depite the winds, it may have had the
structure of a monsoon depression instead of that of a tropical storm.
This system affected the Tuamotu Archipelago. Tuamotu Island reported 43 kt
winds at 2100 UTC 7 February, while Hereheretue Island reported a minimum
pressure of 999.7 mb at 1200 UTC the same day. There are no reports of
damage or casualties at this time.
