Tropical cylone Mahasen hit southern Bangladesh causing the reported deaths of at least 12 people and the destruction of many homes. Mahasen had heavy rains accompanied with tropical storm force winds when it came ashore. The TRMM satellite had two very informative views as deadly tropical Cyclone Mahasen was moving toward and then over Bangladesh. TRMM passed above Mahasen on May 15, 2013 at 2133 UTC and saw Mahasen again on May 16, 2013 at 0406 UTC after the tropical cyclone's center passed over Bengladesh's Ganges Delta. Red tropical cyclone symbols mark Mahasen's locations with both TRMM

Tropical cyclone Mahasen is moving through the Bay of Bengal and is predicted by the Joint Typhoon Warning Center to impact southeastern Bangladesh and northwestern Myanmar (Burma) in about 4 days. This analysis shows a TRMM Multisatellite Precipitation Analysis (TMPA) of rainfall that occurred with tropical cyclone Mahasen during the past week. So far rainfall from Mahasen has fallen mainly over the open waters of the northern Indian Ocean and the Bay Of Bengal. Rainfall totals of about 500mm (~19.7 inches) are shown east of Indonesia in this analysis. Click here to see a rainfall total

The TRMM satellite again flew almost directly above intensifying tropical cyclone Mahasen (01B) on May 11, 2013 at 2157 UTC. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments are shown overlaid on an infrared image from the Visible and InfraRed Scanner (VIRS). TRMM PR data found that the heaviest rainfall was falling at a rate of over 142 mm/hr (~5.6 inches) in a band of powerful storms well to the southwest of Mahasen's center. At the time of this TRMM pass Mahasen's winds were estimated to be about 50kts (~58 mph). Mahasen's winds are predicted to

The TRMM satellite passed above a developing tropical cyclone in the northern Indian Ocean west of Indonesia on May 9, 2013 at 2211 UTC. This image shows that tropical cyclone 01B was already fairly well organized. TRMM's Precipitation Radar (PR) instrument indicated that rainfall was falling at a rate over 178 mm/hr (~5.8 inches) in an area of strong convection in the middle of the forming tropical cyclone. The tropical cyclone is a little unusual because it formed only 4.8 degrees north of the equator. Coriolis force, an artifact of the earth's rotation, is weaker near the equator so

Cyclone Zane, which as of 12:00 UTC (10:00 pm Australian Eastern Standard Time or AEST) 1 May 2013, was located about 215 km (~133 miles) due east of the coast of Queensland, Australia. TRMM captured this recent image of Cyclone Zane at 11:48 UTC (9:48 pm AEST) 1 May 2013. At the time, the center of circulation was located about 215 km (~133 miles) due east of the coast of Queensland, Australia and was heading west-northwest. TRMM reveals that Zane is still not very well organized with no eye visible and very little evidence of banding (curvature) in the rain area. At the time of this image
