Evan

Intensifying tropical cyclone Evan devastated the Samoan Islands when it passed over the islands on December 13, 2012. The TRMM satellite flew directly above Evan today (December 14, 2012) at 0659 UTC when the tropical cyclone was a category 3 on the Saffir-Simpson scale with winds of 100kts (115 mph). TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were used in the rainfall analysis on the first image. TRMM's Precipitation Radar (PR) showed that very intense storms in Evan's eye wall were dropping rain at a rate of up to 147mm/hr (~5.8 inches). The strongest radar reflectivity

The TRMM satellite passed above an intensifying tropical cyclone in the South Pacific Ocean called Evan on December 11, 2012 at 1759 UTC. Evan is predicted to attain hurricane force winds on December 13, 2012 when it is moving through the Samoan Islands. An analysis of Evan's rainfall from TRMM's Precipitation Radar (PR) and Microwave Imager (TMI) shows that Evan already had an eye-like structure at the time of this TRMM orbit.
