TRMM Sees Mahasen (image) NASA/Goddard Space Flight Center Caption When NASA's TRMM satellite passed over Cyclone Mahasen on May 16 at 04:06 UTC (12:04 a.m. EDT), the TRMM Microwave imager showed the heaviest rainfall was occurring in a band of thunderstorms north of the center of circulation. That band of thunderstorms was already over southern Bangladesh and dropping as much as 2 inches/50 mm of rain per hour along the coast.
