TD06 Becomes Tropical Storm Fernanda

The National Hurricane Center (NHC) upgraded tropical depression 06E to tropical storm Fernanda on 16 August 2011 at 0800 UTC after seeing data from a TRMM pass at that time. A rainfall analysis from TRMM Microwave Imager (TMI) rainfall data shows that Fernanda contains areas of heavy rainfall. Fernanda was located about 2378 km (~1478 miles) east-southeast of the Hawaiian Islands with wind speeds of about 45 kts (~52 mph) and was moving toward the west at about 8 kts (~9.2 mph). The NHC discussion says that computer guidance indicates considerably more intensification is possible with

Tropical Storm Gert Dissipating

The TRMM satellite showed that tropical Storm Gert still contained a few potent thunderstorms when it traveled directly over head on 16 August 2011 at 0005 UTC. As predicted by the National Hurricane Center (NHC) Gert passed to the east of Bermuda. Gert is now expected to accelerate movement toward the northeast and dissipate in the cold waters of the Atlantic Ocean.

TRMM Sees Tropical Cyclone Forming

The National Hurricane Center (NHC) has given an area of disturbed weather in the eastern Pacific Ocean a high probability (70%) of becoming a tropical cyclone. The TRMM satellite flew over this disturbance, located about 2,680km (~1,665 miles) east-southeastof the Hawaiian Islands, on 14 August 2011 at 2306 UTC. TRMM's Precipitation Radar (PR) revealed that numerous heavy thunderstorms in an area west of the low pressure center were dropping rain at the rate of over 50mm/hr (~2 inches). TRMM's PR also showed that a few thunderstorm towers near the center of the developing tropical cyclone

Tropical Storm Gert

Tropical Storm Gert became the seventh named tropical cyclone in the Atlantic Ocean basin on Sunday August 14, 2011 at 1800 UTC ( 2 PM EDT). Gert was located southeast of Bermuda and appeared small but well organized when the TRMM satellite flew over on 15 August 2011 at 0101 UTC. A rainfall analysis from TRMM's Microwave Imager (TMI) shows a comma shaped area of moderate to heavy rainfall wrapping around the center of the small storm. The National Hurricane Center (NHC) expects Gert to intensify slightly while passing just to the east of Bermuda. Click here to see earlier TRMM information

Short-Lived Tropical Storm Franklin

Tropical Storm Franklin was only active for a short time but the TRMM satellite had a fairly good view when it passed above on Saturday August 13 at 0115 UTC. TRMM's Microwave Imager (TMI data shows that Franklin was dropping some light to moderate rainfall north-northeast of Bermuda. Franklin became extra-tropical a little later as it moved into the open waters of the north Atlantic.
