The GPM core observatory satellite provided rainfall information about hurricane Gert on August 16, 2017 at 5:37 PM EDT (2137 UTC). At that time Gert was a strong category two hurricane with maximum sustained winds of about 93.5 mph (85 kts). Data from GPM's Microwave Imager (GMI) instrument showed that rain was still falling at a rate of more than 2.94 inches (74.7 mm) per hour in a powerful band of storms spiraling around Gert's eastern side. With that pass GPM's Dual-Frequency Precipitation Radar (DPR) had a limited encounter with hurricane Gert. DPR did find that rain in storms on the

Deaths of over 250 people have resulted from extremely heavy monsoon rainfall in parts of northern India, Bangladesh and Nepal. The death toll from flooding and landslides is expected to continue increasing. Heavy monsoon rainfall is normal in southern Asia this time of year but precipitation totals this year are higher than expected. Recent heavy rainfall is also causing the Brahmaputra and Ganges Rivers rivers to continue rising. This rainfall analysis over southern Asia was created using IMERG real time data covering the period from August 10-16, 2017. Total rainfall IMERG estimates of over

Tropical storm Gert was upgraded to a Hurricane on 1100 PM EDT Monday August 14, 2017 at 11:00 PM (August 15, 2017 0300 UTC). The GPM core observatory satellite flew over the intensifying tropical storm on August 14, 2017 at 7:21 PM EDT (2321 UTC). With winds of about 69 mph (60 kts) Gert was getting close to hurricane intensity. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed heavy rainfall south of Gert's partial eye. GMI showed that rain was falling at a rate of over 1.6 inches (40 mm) in that area. GPM's Radar scanned through

The GPM core observatory satellite passed above tropical storm Gert on August 14, 2017 at 9:36 EDT (1336 UTC) when winds had reached about 57.5 mph (50 kts). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments were used to show the coverage and the intensity of rainfall arround tropical storm Gert. The area covered by GPM's radar swath (shown in lighter shades) revealed that the most intense rainfall, measuring greater than 3.5 inches (90 mm) per hour, was located in bands of rain on the eastern side of the storm. This GPM pass was mentioned

Tropical storm 14W formed in a remote area of the western Pacific Ocean southeast of Wake Island on August 11, 2017. The GPM core observatory satellite flew above the center of the newly formed tropical storm on August 11, 2017 at 0902 UTC. The "core" satellite carries advanced radar and radiometer systems that measure precipitation from space and serves as a standard that is used to unify precipitation measurements from a constellation of research and operational satellites. Tropical storm 14W was revealed by GPM to be small but well organized with very intense convective storms near the
