Tropical storm Carlos is the third tropical cyclone in what promises to be a busy 2015 eastern Pacific hurricane season. The GPM core observatory satellite flew directly above Carlos on June 12, 2015 at 0716 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that heavy rain was falling in a band of powerful storms to the southeast of the tropical storm's center of circulation. Rainfall was measured by GPM radar (Ku band) falling at a rate of almost 70 mm (2.8 inches) per hour in Carlos' most intense areas of rainfall. Those same radar data were

The GPM core observatory had another excellent view of tropical cyclone Ashobaa in the Arabian Sea over on June 8, 2015 at 2131 UTC. As expected, Ashobaa was more powerful than when seen by GPM earlier in the day. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that rain was falling at a rate of over 70.5 mm (about 2.8 inches) per hour in bands of storms west of the center of circulation. Very powerful storms were seen west of tropical cyclone Ashobaa's center of circulation by GPM's Ku Band Radar. A 3-D view constructed from GPM's Ku band radar

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
