WEEKLY TROPICAL CYCLONE SUMMARY #51: JULY 19 - 26, 1992
North Atlantic Basin:
Tropical Depression Two: Tropical Depression Two formed near 29N 63W from
a persistent low pressure area on 24 July. The system initially moved west,
but it turned north-northeast on 25 July. The system then accelerated east-
northeast and dissipated near 31N 57W on 26 July. Maximum winds were estimated
at 30 kt, and the mimimum central pressure measured by reconnaissance aircraft
was 1015 mb. (This system was embedded in a very strong surface high pressure
ridge, so it had tropical cyclone winds and structure at a very much higher
than normal central pressure.) There is a chance that this system might have
reached tropical storm intensity earlier on 24 July, as satellite imagery
suggests that the aircraft did not reach the system until it was starting
to weaken.
Author's Note: The explanation I have recieved from the National Hurricane
Center about calling the system Tropical Depression 2 is that the system
called Tropical Depression Two in June should have been called Tropical De-
pression One.
Eastern North Pacific Basin (E of 140 Deg. W):
Hurricane Frank: At the start of the summary period, Frank was moving
west-northwest with 100 kt winds. Frank continued to move west-northwest as
it weakened below hurricane intensity on 21 July. On 22 July, Frank crossed
into the Central North Pacific with 50 kt winds while continuing to move
west-northwest.
Hurricane Georgette: At the start of the summary period, Georgette was
moving west-northwest with 80 kt winds. Georgette turned west-southwest and
then west on 20 July. This westerly track continued until Georgette crossed
into the Central North Pacific on 24 July. The southward jog brought the
storm over warmer water, and maximum winds increased to a secondary peak of
90 kt on 21 July. This was short-lived as Georgette weakened below hurri-
cane intensity the next day. Georgette continued to weaken, and it fell to
depression intensity on 24 July just prior to reaching 140W.
Tropical Depression 9E: Tropical Depression 9E formed on 26 July near
14N 117W. At the end of the summary period, the system was moving west-
northwest with 30 kt winds.
Central North Pacific Basin (180 Deg. W to 140 Deg. W):
Tropical Storm Frank: Ex-hurricane Frank entered the Central North Pacific
with 50 kt winds while moving west-northwest. The storm continued to weaken,
and it was downgraded to a depression on 23 July. The system dissipated later
that same day near 28N 146W.
Tropical Depression Georgette: Ex-hurricane Georgette entered the Central
Pacific as a 30 kt tropical depression while moving westward and accelerating.
This rapid westward motion continued through the rest of the summary period.
Winds decreased to 25 kt on 25 July then briefly re-intensified to 30 kt later
the same day. At the end of the summary period, maximum winds had again de-
creased to 25 kt. Georgette produced gusty winds, heavy showers, and water-
spouts in and around the island of Hawaii as it passed to the south. There
are no reports of damage or casualties at this time. Georgette's track from
95W to 160W makes it one of the longest continuously tracked systems ever
in the Eastern and Central North Pacific.
Western North Pacific Basin (W of 180 Deg. W):
Typhoon Gary: At the start of the summary period, Tropical Depression 7W
was approaching Luzon Is. in the Philippines moving west with 30 kt winds.
The system crossed Luzon on 20 July and reached tropical storm intensity
soon after emerging into the South China Sea. Gary turned west-northwest on
21 July, and this general motion continued through the rest of its life.
Typhoon intensity was reached just east of Hainan Dao on 22 July. Gary
moved into southern China on 23 July and dissipated over land later that
same day. Peak winds in the storm were 65 kt. Press reports indicate that
11 people were killed and 3 missing in the Philippines due to Gary. There
are no damage or casualty reports from China at this time.
Tropical Storm Helen: Tropical Depression 8W formed very rapidly near
26N 158E early on 26 July. It apparently formed from the surface reflection
of an upper level low pressure system. Moving northward, the system soon
reached a peak intensity of 45 kt. Helen then turned north-northeast and
accelerated, and at the end of the summary period it had 40 kt winds.
North Indian Ocean Basin:
Tropical Cyclone 04B: Tropical Cyclone 04B formed near 20N 87E on 26
July. Moving northwestward, the storm made landfall just east of Cuttack,
India later that same day. Maximum winds prior to landfall were 35 kt.
There are no reports of damage or casualties at this time.
South Indian Ocean Basin (W of 135 Deg. E): No tropical cyclones.
South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
