Hurricane Dorian is packing heavy rain as it moves toward the Bahamas as predicted by NOAA’s NHC or National Hurricane Center. NASA's GPM mission recently analyzed the storm and found heavy rainfall in the storm as it passed through the Caribbean. This image shows estimated rainfall accumulations for the region affected by Hurricane Dorian over the 24 hour period of Aug.27 11:59 UTC to Aug. 28 11:59 UTC. The imagery was generated using the Integrated Multi-satEllite Retrievals for GPM (IMERG) “early run” product. The data indicates that up to 120 mm (4.72 inches) of rainfall accumulated in

In early August 2019 a depression formed in the Bay of Bengal that moved over India contributing to heavy rainfall on India's west coast. NASA's satellite data analysis suggests that from August 5 though 11, two feet of rain fell in some places. This estimate is from the GPM-based realtime multi-satellite algorithm called IMERG, which is run at NASA Goddard. Credit: Owen Kelley (NASA GSFC)

UPDATE 7/17/19: This GPM IMERG animation shows rainfall accumulations from #HurricaneBarry in the Gulf of Mexico from July 11-16, 2019.

The

NASA / JAXA’s GPM Core Observatory passed over developing Tropical Depression 2 (which was upgraded to Tropical Storm Barry later in the morning) in the Gulf of Mexico the morning of July 11th 2019 at 8:26am CT, capturing estimates of rainfall rates within the storm. The first image shows rainfall rates collected by GPM’s Microwave Imager, while the second image shows 3D rainfall rates within the atmospheric column from GPM’s Dual-frequency Precipitation Radar (DPR). The DPR measured storm top heights as high as 18 km, which is extremely high and indicative of intense thunderstorm activity

Washington DC experienced extreme rainfall the morning of July 8th, 2019 when a cluster of slow-moving thunderstorms moving through the area tapped into a very moist airmass to produce extremely heavy rains, which resulted in flash flooding throughout the region. The storms were triggered by a nearby frontal boundary. The GPM Core Observatory passed over this storm system at 8:51am ET, with its Dual-frequency Precipitation Radar measuring rainfall rates in excess of 100 mm/hr in some areas. Reagan National Airport (DCA) also reported receiving 80 mm of rainfall in one hour, corroborating the
