Tropical storm Earl has been intensifying as it moves through the Caribbean Sea. The National Hurricane Center (NHC) now predicts that Earl will be a hurricane before it hits Mexico's Yucatan Peninsula tomorrow afternoon. Earl is predicted by NHC to remain in a light to moderate vertical wind shear environment over very warm sea surface temperatures until landfall. The GPM core observatory satellite passed over intensifying tropical storm Earl in the Caribbean Sea northeast of Honduras on August 3, 2016 at 0356 UTC ( August 2, 2016 11:56 PM EDT). GPM's Microwave Imager (GMI) and Dual-Frequency

Today a tropical wave in the Caribbean Sea south of Cuba developed a closed circulation center and was then designated tropical storm Earl by the National Hurricane Center (NHC). Earl is the fifth tropical cyclone to form in the Atlantic Ocean this year. The GPM core observatory satellite flew over the forming tropical storm on August 2, 2016 at 1436 UTC (10:36 AM EDT). GPM's Microwave Imager (GPM) and Dual-Frequency Precipitation Radar (DPR) data were used in this analysis to show precipitation accompanying Earl. GPM's GMI provided excellent coverage of heavy convective rainfall in the

NASA analyzed rainfall data from slow-moving storms that triggered flash floods over parts of central Maryland and caused devastating flooding in historic Ellicott City, Maryland. A slow-moving line of heavy thunderstorms dumped as much as 6 to 7 inches of rain in about two hours' time during the evening of Saturday, July 30, over parts of Howard County in central Maryland, resulting in severe local flash flooding. The hardest hit area was the historic town of Ellicott City, where two people were trapped in their cars and drowned. The town suffered substantial damage to many buildings

Most of the Hawaiian Islands were spared serious damage from tropical storm Darby. The location of Darby's track through the Hawaiian Islands resulted in the islands of Hawaii and Oahu being the most affected. Flash flooding was common on Oahu due to a reported 177.8 mm (7 inches) of rain drenching the island. Interstate H-1 was flooded in some locations. Lightning damage was reported in Kaneohe on the windward side of Oahu. Estimates of rainfall accompanying tropical storm Darby were produced using NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data. These IMERG rainfall

Tropical storm Darby has caused some heavy rainfall in the Hawaiian Islands since hitting the big island (Hawaii) on Saturday July 23, 2016. After hitting the big island Darby passed to the south of Molokai and Maui. Rain falling at a rate of 25.4 mm (1 inch) to 50.8 mm (2 inches) per hour was reported on the island of Oahu as Darby passed to the southwest of the island. The National Weather Service office in Honolulu reported that parts of Interstate H-1 that serves the southern side of Oahu was closed due to flooding on Sunday night. Darby is affecting northern Kaui today. The GPM core

The eastern Pacific Ocean continues to show that it's environment is favorable for the birth of tropical cyclones. Tropical Depression EIGHT-E (TD08E) quickly followed tropical storm FRANK as the latest example of tropical cyclogenesis in the eastern Pacific Ocean. The GPM core observatory satellite examined TD08E when it flew directly above on July 22, 2016 at 0931 UTC. At that time maximum sustained winds were only estimated to be about 30 kts (34.5 mph). Rainfall was examined in TD08E using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR)

The eastern Pacific Ocean continues to spawn tropical cyclones. Seven named tropical cyclones have already formed in the Eastern Pacific ocean this year. The National Hurricane Center (NHC) has indicated that another tropical cyclone is likely to form in a broad area of low pressure southwest of Acapulco, Mexico. The GPM core observatory satellite flew directly above this increasingly organized stormy area on July 21, 2016 at 0851Z. GPM found that powerful thunderstorms in that area contained intense showers. Rain was measured by GPM's Dual-Frequency Precipitation Radar (DPR) instrument

The GPM core observatory satellite traveled above tropical storm Estelle on July 19, 2016 at 1036 UTC. This pass showed that Estelle contained well organized convective bands that were producing precipitation within the storm. Precipitation within Estelle was analyzed using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. GPM's radar (DPR Ku band) data were used to perform a 3-D examination of the precipitation on the eastern side of tropical storm Estelle. Some rainfall was measured by DPR falling at a rate of over 65 mm (2.6 inches) per

Tropical cyclone 01S (Abela) formed in the South Indian Ocean on July 16, 2016. Abela was the first tropical Cyclone to form in July over the South Indian Ocean since 2007 so it is a little unusual. The GPM core observatory satellite recently had two good views of Abela. GPM saw the newly formed tropical cyclone on Jul 16, 2016 at 2216 UTC. Precipitation data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that ABELA contained a large area of rainfall on July 16, 2016. Then again on July 18, 2016 at 2206 the satellite passed above after

The PPS (Precipitation Processing System) will be down today, July 19, 2016 from 8:00am -14:00pm EDT (12:00 - 18:00 UTC). for scheduled maintenance. During this time all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable. You may contact PPS Operations at helpdesk@mail.pps.eosdis.nasa.gov You will be informed when PPS systems become available. We apologize for any inconvenience this may cause.
