WEEKLY TROPICAL CYCLONE SUMMARY #155 JULY 17-24, 1994
North Atlantic Basin:
Tropical Depression Two: Tropical Depression Two formed just off the South
Carolina coast near 33N 79W on 20 July. The system moved northwestward into
South Carolina and weakened to a low pressure area later that day. Maximum
sustained winds in this short-lived system were 30 kt. The Frying Pan Shoals
automated station reported 29 kt sustained winds at 1200 UTC, while Myrtle
Beach, South Carolina, reported a gust to 36 kt at 1934 UTC. The lowest
pressure was 1015 mb measured by reconnaissance aircraft just prior to
landfall. Rainfalls of up to 5 in (127 mm) occurred over parts of South and
North Carolina. There are no reports of damage or casualties at this time.
Eastern North Pacific Basin (E of 140 Deg. W):
Tropical Storm Fabio: Tropical Depression 6E formed near 13N 126W on 19
July. Initially moving west-northwest, the system reached a peak intensity
of 40 kt later that day. Fabio continued west-northwest as it weakened to a
depression on 20 July, then it turned west the next day. Fabio continued
this track as it moved into the Central North Pacific near 17N 140W on 22
July.
Hurricane Gilma: Tropical Depression 7E formed near 12N 123W on 21 July.
Initially moving west, the system continued this motion through the west of
the summary period. TD-7E reached tropical storm intensity on 22 July and
hurricane intensity the next day. Rapid strengthening continued, and Gilma
was packing 130 kt winds when it crossed into the Central North Pacific near
12N 140W on 24 July.
Central North Pacific Basin (180 Deg. W to 140 Deg. W):
Hurricane Emilia: Emilia entered the Central North Pacific on 17 July
near 10N 140W. At the time, it was moving west with 75 kt winds. Rapid
strengthening ensued, and Emilia's wind increased to 130 kt by the end of 18
July. Emilia turned west-northwest on 19 July as it reached a peak intensity
of 140 kt. The storm continued this track and intensity on 20 July, then
it turned northwest and weakened the next day. Emilia turned back toward the
west-northwest on 22 July as it weakened to a minimal hurricane. This track
continued the next day as the cyclone weakened to a minimal tropical storm.
Further weakening followed, and at the end of the summary period, Emilia
was southwest of the western Hawaiian Islands tracking west-northwest with
25 kt winds.
Emilia is the strongest hurricane of record in the Central North Pacific.
Reconnaissance aircraft measured a minimum central pressure of 926 mb on
several occasions on 19-20 July. This was lower than the 937 mb aircraft
pressure in Hurricane Iniki in 1992. One remarkable feature was the rapid
rise in central pressure during weakening. At 0500-0600 UTC 21 July, the
pressure was measured at 936 mb. 30 hr later, it had risen to 990 mb. For-
tunately, Emilia did not affect any land areas. It did pass over buoy 51002
as it weakened. The buoy measured sustained winds of 47 kt with gusts to 60
kt at 0800 UTC 22 July. A minimum pressure of 990.1 mb was observed 2 hr
later.
Tropical Depression Fabio: Fabio entered the Central North Pacific near
17N 140W on 22 July, moving west with 25 kt winds. The depression continued
west until it dissipated near 17N 154W on 24 July.
Hurricane Gilma: Gilma entered the Central North Pacific near 12N 140W on
24 July. It continued westward, and at the end of the summary period it was
packing winds estimated at 140 kt.
Western North Pacific Basin (W of 180 Deg. W):
Typhoon Walt: At the start of the summary period, Walt was moving east-
northeast with 60 kt winds. Walt moved generally northeast to north-northeast
through 20 July. The storm reached typhoon intensity on 18 July, followed by
rapid strengthening to a peak intensity of 130 kt on 19 July. Walt turned
northwest on 21 July, followed by a westward turn the next day as it weakened
to a tropical storm. The storm then slowed to an erratic drift near 30N 132E
on 23 July, followed by a north-northeast drift toward southwestern Japan the
next day. At the end of the summary period, Walt was just south of Japan
with 55 kt winds. Walt passed near buoy 21004 on 22 July, which reported 44
kt sustained winds at 0100 UTC and a pressure of 975.7 mb at 0600 UTC. Also,
Muruotomisaki, Japan reported 49 kt sustained winds at 2100 UTC 24 July. There
are no reports of damage or casualties at this time.
Typhoon Zeke: Tropical Depression 12W formed near 22N 137E on 17 July.
Initially moving east-northeast, this general motion continued through 19
July. The depression reached tropical storm strength on 19 July, and it
maintained 35-40 kt sustained winds until 21 July. Zeke turned northeast on
20 July, then it turned north on 21 July as it reached a peak intensity of
65 kt. This was based on a 65 kt ship report near the center. Zeke continue
north the next day as it weakened to a tropical storm, then it turned north-
east on 24 July. At the end of the summary period, Zeke was moving northeast
with 40 kt winds.
Tropical Storm Yunya: Tropical Depression 11W formed near 16N 118E on 18
July. Initially moving northeast, the system reached tropical storm inten-
sity later that day before tracking across the northwest corner of Luzon
Island in the Philippines. Vigan reported a pressure of 992.8 mb at 2300 UTC
18 July. Yunya moved northeast into the Philippine Sea on 19 July as it
reached a peak intensity of 45 kt. It turned east as it weakened to a
depression on 20 July, and it dissipated the next day near 21N 134E. Although
this system affected the Philippines, there are no reports of damage or
casualties at this time.
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.
