Heavy rainfall has recently caused widespread flooding and landslides in Jamaica. Occasional showers from trade winds are normal in Jamaica but recent rainfall from slow moving troughs have been unusually heavy. A 1009 mb low pressure center located in the western Caribbean was disrupting the normal trade winds over Jamaica today. This rainfall analysis was constructed using data from NASA's Integrated Multi-satelliE Retrievals for GPM (IMERG). Data collected in near-real time were utilized in IMERG's rainfall accumulation estimates for the Caribbean. This analysis covers the period from May

PPS is releasing GPM V05 DPR L1-L3 and Combined L2 and L3 V05 data products today, Wednesday May 17, 2017. This V05 data will be available beginning with May 01, 2017 data and forward. The DPR Level 3 monthly products will be released when validated. Reprocessed V05 DPR and Combined data for March 2014 through April 2017 will take several weeks to complete. This data will appear in PPS's arthurhou archive as we reprocess (6 to 8 weeks - estimated completion time). Registered users can obtain data from: ftp://arthurhou.pps.eosdis.nasa.gov/ and can order this through STORM: https://storm.pps

On May 10, 2017 rapidly dissipating tropical Cyclone Donna moved to the southeast of New Caledonia in the South Pacific. In addition to being the most powerful out-of-season tropical cyclone ever recorded in the southern hemisphere, Donna also dropped extreme amounts of rainfall along it's path. Donna spread heavy rainfall along it's path from northern Vanuatu through the Loyalty Islands east of New Caledonia. Over 250mm (~10 inches) of rainfall was reported in the islands of northern Vanuatu as Donna was moving through on May 5, 2017. This rainfall analysis was constructed using data from

The GPM core observatory satellite flew over intensifying tropical cyclone Ella in the South Pacific on May 10, 2017 at 2301 UTC. The satellite's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed bands of curved rainfall bands wrapping into the center of a well defined center of circulation. GPM's DPR measured rain falling at a rate of over 231 mm (9.1 inches) per hour in an intense feeder band on Ella's eastern side. This 3-D view of tropical cyclone Ella was produced using GPM radar reflectivity data (DPR Ku Band). DPR showed that the highest storm tops

The above window displays an interactive visualization of GPM data collected from Tropical Cyclone Donna on 5/7/17. Over the weekend tropical cyclone Donna dropped very heavy rain over Vanuatu as it moved toward the west of the islands. Donna had intensified and had maximum sustained winds of 115 kts (132 mph) on Monday morning. This made it the equivalent of a category four on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite had two excellent views of the intensifying tropical cyclone Donna on succeeding days. When GPM flew over Donna on May 6, 2017 at 0146 UTC the
