Tropical storm 14W formed in a remote area of the western Pacific Ocean southeast of Wake Island on August 11, 2017. The GPM core observatory satellite flew above the center of the newly formed tropical storm on August 11, 2017 at 0902 UTC. The "core" satellite carries advanced radar and radiometer systems that measure precipitation from space and serves as a standard that is used to unify precipitation measurements from a constellation of research and operational satellites. Tropical storm 14W was revealed by GPM to be small but well organized with very intense convective storms near the

The GPM core observatory satellite passed above tropical storm Gert on August 14, 2017 at 9:36 EDT (1336 UTC) when winds had reached about 57.5 mph (50 kts). Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments were used to show the coverage and the intensity of rainfall arround tropical storm Gert. The area covered by GPM's radar swath (shown in lighter shades) revealed that the most intense rainfall, measuring greater than 3.5 inches (90 mm) per hour, was located in bands of rain on the eastern side of the storm. This GPM pass was mentioned

Tropical storm Gert was upgraded to a Hurricane on 1100 PM EDT Monday August 14, 2017 at 11:00 PM (August 15, 2017 0300 UTC). The GPM core observatory satellite flew over the intensifying tropical storm on August 14, 2017 at 7:21 PM EDT (2321 UTC). With winds of about 69 mph (60 kts) Gert was getting close to hurricane intensity. Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed heavy rainfall south of Gert's partial eye. GMI showed that rain was falling at a rate of over 1.6 inches (40 mm) in that area. GPM's Radar scanned through

As expected, tropical storm Franklin intensified and was upgraded to hurricane Franklin in the afternoon of August 9, 2017. Franklin made landfall on the coast of eastern Mexico early this morning as a category 1 hurricane with winds of over 86 mph (75 kts). Heavy rainfall, flash floods and mudslides are expected as Franklin moves inland and weakens. The remnants of Franklin may survive the transit over Mexico's rough terrain and revive after moving into the eastern Pacific Ocean. The GPM core observatory satellite saw tropical storm Franklin with winds of about 69 mph (60 kts) as it was

For V05 we produced a daily gridded text product for precipitation data from the core satellite and from the partner constellation imagers. We also produced a monthly rollup of these gridded text products. They were all designated with the product version V05A. If you downloaded these products, we regret to inform you that we found an error in the calculation of convection rate and frozen rate. While the mean precipitation rate values were correct in V05A, convective and frozen rates were erroneous. We have made the necessary changes to the code that produces these products. After extensive
