Fred

GPM Overpass of Tropical Cyclone Fred on August 16, 2021.
Tropical Storm Fred, the 6th named storm of the 2021 Atlantic hurricane season, began as a westward moving disturbance in the central Atlantic east of the Lesser Antilles. The system passed through the southern Leeward Islands during the early morning hours of August 10 but still lacked a well-defined center of circulation. Despite significant thunderstorm activity within the system, it wasn’t until late that evening, when the system was passing just south of Puerto Rico, that the National Hurricane Center (NHC) identified a well-defined circulation and upgraded the system to Tropical Storm

Fred became the first Cape Verdes hurricane of the 2015 Atlantic season when it was upgraded from a tropical storm on August 31, 2015 at 0600 UTC (2 AM AST). The GPM core observatory satellite flew over on August 30, 2015 at 0236 UTC when Fred was forming from a tropical wave that moved off the African coast. Rainfall was measured by GPM's Dual-Frequency Precipitation Radar (DPR) at the extreme rate of close to 128 mm (5.0 inches) per hour. Rainfall in towering convective thunderstorms at Fred’s center of circulation were providing the energy necessary for intensification into a hurricane
