While the GPM Core Observatory’s instruments show exceptional detail in Milton’s rainfall structure in several overpasses throughout the week, the IMERG global multi-satellite product provides a broader overview of precipitation along Milton’s track as a continuous picture from development through landfall. Download this video (right-click -> "save as") The above animation shows IMERG precipitation rates (in blue/yellow shading) and accumulations (in green/purple shading) from Oct. 5-10, 2024. Cloudiness is shown in shades of white/gray using infrared geosynchronous satellite data. While

Updated Oct. 10, 2024 Click here for a visualization of IMERG precipitations and totals from Hurricane Milton. After forming in the Bay of Campeche, Hurricane Milton underwent a remarkable period of rapid intensification with its central pressure falling from 1007 mb (29.74 inches of mercury, inHg) at 11:00 a.m. EDT Oct. 5 to 897 mb (26.49 inHg) at 8:00 p.m. EDT on Oct. 7. At this time Milton became the fifth most intense hurricane in the Atlantic Basin on record in terms of central pressure, just behind Hurricane Rita (2005) on that list, and only the sixth storm in the Atlantic to have a

After tracking through the eastern Gulf of Mexico and battering much of the west coast of Florida with strong winds and storm surge, Hurricane Helene made landfall in the Big Bend region of Florida’s northwest coast at 11:10 pm EDT about 10 miles west-southwest of Perry, Florida, as a powerful Category 4 hurricane with maximum sustained winds reported at 140 mph by the National Hurricane Center (NHC). Hurricane Idalia, a strong Category 3 storm at the time, also made landfall in the Big Bend last year. Animation of NASA IMERG precipitation rates and totals from Hurricane Helene from Sept. 23 -

[ Goto Spanish translation; Ir a la traducción al español ] On Monday evening, Sept. 23, 2024, an unusual hurricane struck southern Mexico, dumping 20 inches of rainfall along the coast according to estimates from NASA's IMERG precipitation product. The following image shows these rainfall estimates: Click here for a full resolution version of this image. Observations from an international constellation of satellites were the starting point for calculating these estimates, and the data confirm that forecasters in prior days were right to warn of possible heavy rainfall. Forecasters did have

Nov. 14, 2024, 8:00 p.m. ET Register Here Overview As we finish celebrating the NASA / JAXA Global Precipitation Measurement (GPM) mission's 10 year anniversary, we'll take a look behind the scenes at how the GPM Outreach Team showcased the mission's science, technology, and applications over the years. We'll also look ahead to the exciting new plans for the future of NASA’s precipitation measurement missions!
