Effective 27 January 2018 all the IMERG Early products have a retrospective V05B processing for the entire GPM mission starting in March 2014. All V04 products have been saved in a V04 directory. V03 products are no longer available. Effective 27 January 2018 IMERG Late products have a retrospective V05B processing from the beginning of the mission in March 2014 to January 2017. We continue to process Late products and they should be completed in another week. We are also working on retrospective processing to V05B of the GIS friendly TIFF IMERG based products. These should all be at V05B in

Tropical cyclone BERGUITTA was moving very close to the eastern side of the island of Mauritius when the GPM core observatory satellite passed above on January 18, 2018 at 0528Z (9:28 AM local time). This meant that the most destructive section of tropical cyclone BERGUITTA was passing very close to the eastern side of Mauritius. For this reason the eastern side of Mauritius would be expected to have had the highest winds, seas, and storm surge from BERGUITTA. The tropical cyclone was passing a little farther to the east of the island of Reunion. Data collected by GPM's Microwave Imager (GMI)

The GPM core observatory satellite passed over the southwest Indian Ocean on January 16, 2018 at 1856 UTC. GPM showed that heavy rainfall within tropical cyclone BERGUITTA was moving closer to the islands of Reunion and Mauritius. GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments found that powerful storms northeast of Mauritius were dropping rain at a rate greater than 54 mm (2.1 inches) per hour. A 3-D view of Storm top heights within tropical cyclone BERGUITTA was made possible with GPM's radar (DPR ku Band). Those 3-D scans through the eastern side of

Tropical cyclone BERGUITTA formed in the southwestern Indian Ocean northeast of the islands of La Reunion and Mauritius on January 12, 2018. BERGUITTA is now moving toward the southwest and threatening the islands. Early on January 16,2018 BERGUITTA had maximum sustained winds estimated at 100 kts (115 mph). This means that BERGUITTA was the equivalent of a category three hurricane on the Saffir-Simpson hurricane wind scale. Later in the day BERGUITTA's maximum sustained wind speeds were estimated at 85 kts (98 mph) with gust to 105 kts (121 mph). On January 16, 2018 at 1200Z tropical cyclone
