The AIRS instrument aboard NASA's Aqua satellite captured infrared imagery of System 92W on Oct. 22 at 1:05 p.m. EDT that showed the strongest thunderstorms were fragmented in a band that were wrapping loosely into the center of circulation. Those thunderstorms are reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius).

NASA Sees Strength in Developing Tropical System 92W Approaching Philippines

Residents of the Philippines are preparing for another tropical system that appears to be getting organized on infrared satellite imagery from NASA. The low pressure area called System 92W is developing as it moves west through the Philippine Sea toward the Philippines.

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of System 92W on Oct. 22 at 1:05 p.m. EDT that showed the strongest thunderstorms were fragmented in a band that were wrapping loosely into the center of circulation. Those thunderstorms are reaching high into the troposphere where cloud top temperatures are as cold as -63 Fahrenheit (-52 Celsius).

Today, Oct. 23, the Philippine Atmospheric, Geophysical and Astronomical Services Administration, or PAGASA, issued a public storm warning in preparation for the approach of the low pressure area currently known as System 92W. PAGASA has already given the low its own designation in the Philippines and calls it "Tropical Depression Ofel."

PAGASA posed Public storm warning signal #1 for the Visayas province of Leyte, Southern Leyte, Eastern and Western Samar, Bohol and Camotes Island; also for the Mindanao provinces of Dinagat, Surigao Provinces. Agusan Provinces, Camiguin Island and Misamis Oriental.

At 1030 UTC (6:30 a.m. EDT) on Oct. 23, the center of System 92W was located near 8.6 north and 128.5 east, about 575 miles southeast of Manila, Philippines. It was moving to the west at 8 knots. A forecast track from the Philippines takes the storm into the east central Philippines in the next day or two.
