WEEKLY TROPICAL CYCLONE SUMMARY #133 FEBRUARY 13-20, 1994

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): No tropical cyclones.

North Indian Ocean Basin: No tropical cyclones.

South Indian Ocean Basin (W of 135 Deg. E): Three tropical cyclones!

Tropical Cyclone Hollanda (TC-15S):
The transition to an extratropical cyclone had completed early on the
14th near 31S 55E, as Hollanda continued to recurve into the westerlies,
with a southeast motion of 7 knots, and max sustained winds decreased to
40 knots. No significant ship reports were noted with Hollanda this
summary period.

Tropical Cyclone Ivy (TC-16S):
At the beginning of the summary period, maximum sustained winds remained
near 60 knots as Ivy had turned on a definite southwesterly track. Ivy
continued its parallel of Hollanda's track, as shearing began to weaken
16S. Maximum sustained winds had decreased to 45 knots on the 15th near
19.5S 62.5E, as Ivy became an exposed low level swirl in the cloud field.
But all was not lost for Ivy, as forward motion began to slow and the shear
in its environs lessened. Thunderstorm activity began to increase once
again late on the 15th, and Ivy began to reintensify. Intensification
accelerated on the 16th, as 16S meandered slowly south. Maximum sustained
winds peaked at 100 knots at 0600Z on the 17th near 24S 62.6E.

Motion continued to slow on the 17th and 18th as Ivy encountered a ridge
of high pressure to its south, but the flow aloft did not slow at all!
Shearing resumed and Ivy was last seen dissipating at 1800Z on the 19th
near 26S 60E, being steered by the low level flow around the ridge, moving
southwest at 5 knots. No ship reports were ever observed near Ivy.

Tropical Cyclone 17S (No name designated):
Late on the 16th, Guam spotted a suspicious low pressure area residing off
the northwest coast of Australia. By late on the 17th/early on the 18th,
this low had developed into 17S near 15S 121E. Initially the steering
currents around this cyclone were weak, and 17S chose to drift landward
at a lazy 2 knot pace. Motion soon began to become more southerly, and
eventually southwesterly, while maintaining close proximity to the coast.
The land took its toll on 17S, and the cyclone was last seen dissipating
near 20S 119.5E. Maximum sustained winds never exceeded 35 knots, according
to the advisories from Guam. Two ships reported from port... the ship SHIP
recorded max winds of 30 knots 400 miles ENE of the center with a pressure
of 997.5 mb. The ship VJJJ observed winds of 27 knots and a pressure of
1000.0 mb at 0600Z on the 18th while located 400 miles east of the center.
The system had a monstrous circulation... reminiscent of the depression
last week and Sadie the week before. No land reports were able to be
found with 17S.

South Pacific Ocean Basin (E of 135 Deg. E): No tropical cyclones.
