A rare tropical cyclone in the Arabian Sea west of India was seen by the GPM core observatory satellite when it flew over on the morning of June 8, 2015 at 0811Z. Tropical cyclone Ashobaa (TC01A) had sustained wind speeds of about 40 kts (46 mph) when the satellite passed over head. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments measured rain falling at a rate of over 60 mm (2.3 inches) per hour in strong thunderstorms southwest of the storm's center of circulation. A 3-D view was constructed using data from DPR Ku band radar data. This 3-D view of GPM

Monsoon rainfall, although a little later than normal, has started in southern India. Due to El Nino conditions India's monsoon is predicted to bring below normal rainfall this year. Cooling rainfall comes to the country after high temperatures preceding the monsoon have caused the reported deaths of over 2300 people. Data from the NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) was used in this animation to show the advent of India's monsoon. Rainfall estimates for the past few days (4-5 June 2015) show that some heavy showers have dropped over 120mm (4.7 inches) of rain in the

After moving very little for the last few days hurricane Blanca has again started to move toward the Baja Peninsula. The GPM core observatory satellite passed directly over Blanca on June 4, 2015 at 2056 UTC when the hurricane had maximum sustained wind speeds of about 85 kts (~98 mph). GPM discovered that Blanca had very little convective rainfall in the center of a large cloudy eye. The satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (Ku Band) instruments measured rain falling at a rate of over 85mm (3.3 inches) per hour in a band of powerful storms moving around

Today a new tropical storm called Blanka formed in the eastern Pacific Ocean off southwestern Mexico. The GPM core observatory satellite flew over the forming tropical storm on June 1, 2015 at 1031 UTC (5:31 AM CDT). Rainfall data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments are shown The location of Blanka's center of circulation within a large area of convective thunderstorms was clearly outlined by GPM's GMI derived rainfall. A 3-D view derived from DPR's Ku Band radar data shows that several areas of intense rainfall were located east

Tropical storm Andres became the first tropical storm of the the 2015 Eastern Pacific hurricane season today at 1500 UTC (9 AM MDT). The GPM core observatory satellite flew over the intensifying tropical cyclone (TD1E) at 1225 UTC ( 6:25 AM MDT). Rainfall data from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (Ku Band) instruments are shown overlaid on an enhanced GOES-EAST satellite infrared image received at 1230 UTC (6:30 AM MDT). Rain was found by GMI to be falling at a rate of over 60 mm (2.4 inches) per hour in powerful convective storms near Andres' center. Data
