Tropical cyclone Chapala had entered the Gulf Of Aden when the GPM core Observatory satellite passed over on November 2, 1015 at 0311 UTC. Chapala still had maximum sustained winds estimated at about 105kts (121 mph) making it a category three tropical cyclone on the Saffir-Simpson hurricane wind scale. GPM's Microwave Imager (GMI) found that Chapala was dropping rainfall at a rate of over 65 mm (2.6 inches) per hour in intense storms southwest of Chapala's well defined eye. The Joint Typhoon Warning Center (JTWC) predicts that Chapala will weaken before landfall. Chapala is expected to have

Powerful tropical cyclone Chapala continues moving inexorably toward Yemen. Chapala has weakened from category four intensity a couple days ago while maintaining a course that steers it toward Yemen. The GPM core observatory satellite had a good look at tropical cyclone Chapala on October 31, 2015 at 0331 UTC. GPM's rainfall data are shown overlaid on a 0330Z METEOSAT-7 Visible/Infrared image. At that time Chapala was a very powerful tropical cyclone with maximum sustained winds of about 117 kts (135 mph). GPM's Microwave Imager (GMI) instrument measured rain dropping at a rate of over 88 mm

Tropical Cyclone Chapala developed in the very warm waters of the Arabian Sea west of India on October 28, 2015. These images show rainfall derived from data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. The GPM core observatory satellite had good views of the tropical cyclone on October 29, 2015 at 0332 and 1456 UTC. GPM's rainfall from the first pass show that Chapala was close to hurricane intensity with the location of a developing eye clearly shown by GMI. By the second pass Chapala's maximum sustained winds were estimated at 65 kts

Patricia, the most powerful hurricane on record in the Western Hemisphere, quickly lost power as it moved over Mexico. Then an upper-level low pressure system and the remnants of hurricane Patricia combined to cause very heavy rain in Texas. On Sunday October 25, 2015 eastern Texas, Louisiana and Mississippi were also warned of flooding as extreme rainfall moved eastward along the Gulf Coast.

After maintaining hurricane intensity for over a week former category four hurricane Olaf is now a weakening tropical storm. The GPM core observatory satellite flew above Olaf on October 26, 2015 at 0510Z. Rainfall derived from data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments is shown here. Olaf had moved over cooler waters that were sapping the tropical cyclone's energy. GPM's GMI found that storms located in a small area within Olaf were still dropping rain at a rate of over 65 mm (2.6 inches) per hour. GPM's radar (DPR Ku band) sliced
