Tropical Storm 94B

A low pressure system has been moving through the Northern Indian Ocean over the last couple of days and infrared satellite imagery from NASA's Aqua satellite revealed strong convection in its eastern side and strong wind shear.

At 1800 UTC (1 p.m. EST) on Dec. 6, the center of the low pressure area known as 94B was located east of India's southeast coast over the Bay of Bengal. 94B's center is about 225 miles northeast of Colombo, Sri Lanka near 11.4 North and 84.0 East.

When NASA's Aqua satellite passed over the low on Dec. 6 at 07:59 UTC (2:59 a.m. EST), its Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of the storm's clouds. The image revealed that the western half of the low is already over land as a result of strong wind shear, while the eastern half of the storm and its center of circulation are over open waters in the Bay of Bengal. AIRS data showed that the eastern half of the low had the strongest convection and thunderstorms as infrared data revealed that cloud tops are so high that they are at least -63 degrees Fahrenheit (-52 Celsius) or colder.
