Today tropical cyclone LEHAR's estimated sustained wind speeds reached 65kts (~75 mph). The most powerful tropical cyclone in the Bay Of Bengal this year was deadly tropical cyclone PHAILIN that moved through the area in October with wind speeds of 140kts (~161 mph). This means that LEHAR is the second most powerful tropical cyclone to form in the Bay Of Bengal this year. The TRMM satellite collected data used in the image on the left when the TRMM satellite passed above LEHAR on November 24, 2013 at 1812 UTC. At that time LEHAR was intensifying with tropical storm force winds estimated to be

Tropical cyclone Helen was the fourth named tropical cyclone in the Bay Of Bengal this year when it formed on November 19, 2013. The image on the left shows tropical cyclone Helen as the TRMM satellite flew over on November 21, 2013 at 0606 UTC when Helen had reached peak intensity of about 60kts (~69 mph). The image on the right uses data captured on November 22, 2013 at 0510 UTC when tropical cyclone HELEN was hitting India's east-central coastline. Precipitation data derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that Helen was dropping rain at a

The TRMM satellite passed directly above tropical storm Melissa's center of circulation on November 20, 2013 at 1121 UTC (6:21 EST). TRMM's Precipitation Radar (PR) instrument found that rain was falling at a maximum rate of 55 mm/hr (~2.2 inches) in an area just to the southeast of Melissa's center of circulation. TRMM Precipitation Radar data were also used in the image on the right to show Melissa's 3-D structure. The tallest towers, reaching heights of over 13km (~8 km), were located in a band of rainfall to the northwest of Melissa's center. The strongest intensity radar echo of over
