GPM IMERG Measures Hurricane Dorian's Rainfall from the Caribbean to Canada

Hurricane Dorian (2019) brought heavy rain to the Caribbean, along the US East Coast, and up to Canada. NASA satellite-based precipitation estimates tracked the storm throughout its lifetime, as shown by the sequence of images below. September 3, 2019: Hurricane Dorian over Grand Bahama and Abaco Islands In the early hours of Tuesday, September 3, Hurricane Dorian had been stationary over the island of Grand Bahama for 18 hours, most of the time as a category 5 hurricane. Storm-total rain accumulation over parts of Grand Bahama and Abaco islands have exceeded 24 inches according to NASA

Heavy Rain Leads to Flooding in Brazil

UPDATE 2/12/2020: An extended IMERG analysis of rainfall in Brazil shows even more extreme rainfall occurring in the first weeks of February, with large regions experiencing rainfall totals over 18 inches since the start of 2020. According to local authorities, the region has already received 98% of the rainfall that is typically expected to fall during all of February. UPDATE 1/30/2020: During January 2020, parts of the Brazilian states of Minas Gerais and Espirito Santo experienced above average rainfall, causing deadly floods in the region. Part of the month's heavy rainfall came from a

Credit: Jason West (KBR / NASA GSFC) From Sunday, April 12th, 2020 into Monday the 13th, a series of powerful thunderstorms developed across the southern U.S., bringing heavy rainfall and spawning several destructive tornadoes. This animation shows rainfall estimates for the region for April 11th - 13th derived from NASA's Integrated Multi-satellite Retrievals for GPM (IMERG) data product, along with NOAA tornado reports (red triangles).

GPM Observes Hot Tower in Florida Squall Line

At 9:26pm on Sunday April 19, 2020, NASA's GPM satellite observed an extremely vigorous convective storm cell embedded within a squall line that had produced tornadoes earlier that evening along the US Gulf Coast. NASA's GPM satellite flew over the portion of this squall line that extended over the Atlantic Ocean, 350 miles (500 kilometers) east of Florida's Coast. The Dual-Frequency Precipitation Radar (DPR) observed a storm cell whose updrafts were strong enough to lift small ice particles into the stratosphere 15.8 km above the ocean surface. Equally remarkable is that the updrafts were
