GPM Satellite Sees Tropical Storm Irma Forming Near Cape Verde Islands

GPM Satellite Sees Tropical Storm Irma Forming Near Cape Verde Islands
The National Hurricane Center (NHC) upgraded a low pressure area in the far eastern Atlantic Ocean to tropical storm Irma on August 30, 2017 at 11:00 AM AST (1500 UTC). Tropical cyclones that form in that part of the Atlantic Ocean are often the largest and most powerful hurricanes of the season. Hurricanes Ivan (2004), Isabel (2003), Hugo (1989) and Allen (1980) are examples of past powerful hurricanes that formed near the Cape Verde islands. The GPM core observatory satellite flew above forming tropical storm Irma on August 30, 2017 at 1:56 AM EDT (0556 UTC). This new tropical cyclone was

NASA's IMERG Shows Rainfall Accumulation Along Harvey's Track

NASA's IMERG Shows Rainfall Accumulation Along Harvey's Track
Total rainfall estimates from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG) data are shown here for the period from August 23-29, 2017. During this period hurricane Harvey dropped heavy rainfall as it moved through the Gulf Of Mexico and stalled over Texas. It has been reported that Harvey dropped over 40 inches (1016 mm) of rain over southeastern Texas during this period. Hurricane Harvey's locations and track are shown here overlaid in white IMERG Data are produced using data from the satellites in the GPM Constellation, and is calibrated with measurements from the GPM Core

Harvey Hits Texas, Unleashes Major Flooding

Harvey Hits Texas, Unleashes Major Flooding
Monday, August 28, 2017
Despite its earlier demise, after rejuvinating over the warm waters of the Gulf of Mexico, Hurricane Harvey has become a major weather maker as it unleashes historical flooding over parts of coastal Texas. Harvey began on the 17th of August as a weak tropical storm about 250 miles (~400 km) east of Barbados in the Leeward Islands. Over the next two days, Harvey continued moving steadily westward passing through the Leeward Islands as a still weak tropical storm and entered into the east central Caribbean. On the 19th, Harvey succumbed to the effects of northeasterly wind shear over the central...

GPM's Radar Measures Intense Rain In Hurricane Harvey

GPM's Radar Measures Intense Rain In Hurricane Harvey
Hurricane Harvey's has continued to intensify today as it moves toward the Texas coast. Bands of rain from the hurricane were affecting the Gulf coast from Louisiana to southeastern Texas. The Global Precipitation Measurement (GPM) mission core observatory satellite had another look at hurricane Harvey on August 25, at 7:50 AM CDT (1150 UTC) as it was menacing the Texas gulf coast. GPM's Dual-Frequency Precipitation Radar (DPR) instrument scanned precipitation within powerful storms wrapping around the eastern side of the hurricane. DPR found that intense storms in that area were dropping rain

GPM Observes Intensifying Hurricane Harvey's Rainfall

GPM Observes Intensifying Hurricane Harvey's Rainfall
UPDATE: View the latest GPM overpass from 8/25/17 1141 UTC using the STORM Event Viewer: https://storm.pps.eosdis.nasa.gov/storm/cesium/EventViewer.html?positio… Hurricane Harvey has continued to intensify after regenerating in the southwestern Gulf of Mexico on Wednesday. Harvey's intensification has been aided by moving through an environment that includes low vertical wind shear and the warm waters in the Gulf Of Mexico.
