Hurricane Iselle has weakened from a very dangerous category four hurricane on August 4, 2014 to a category one hurricane when the TRMM satellite passed over on August 6, 2014 at 1020 UTC. Rainfall data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) are shown overlaid on an enhanced infrared image from the 1000 UTC GOES-WEST satellite. TRMM TMI showed that heavy rainfall was occurring around the filling eye. TRMM TMI indicated that the most intense rain was falling at a rate of over 43.5 mm (about 1.7 inches) in a band southwest of the eye. The second image is an animation

Typhoon Halong was a very dangerous category 5 typhoon a few days ago. Halong was still a strong violent category 2 typhoon with winds of 85kts (about 98 mph) when the TRMM satellite saw it on August 5, 2014 at 1550 UTC. Rainfall derived from TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data is shown overlaid on an enhanced MTSAT infrared image received at 1600 UTC. Rain was shown by TRMM PR to be falling at a rate of over 87 mm (about 3.4 inches) per hour south of the Halong's eye. Typhoon Halong is predicted by the Joint Typhoon Warning Center (JTWC) to hit southern Japan with

The hurricane season in the eastern Pacific Ocean has been very active this year. Eleven named tropical cyclones have already formed in the eastern Pacific Ocean. Tropical storm Julio that formed yesterday is following almost the same path as hurricane Iselle toward the central Pacific and the Hawaiian Islands. The TRMM satellite flew over tropical storm Julio on August 5, 2014 at 0944 UTC and collected data used in these images. The first image shows a rainfall analysis derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) overlaid on an enhanced GOES-WEST image received at
