GPM Sees Powerful Winter Storm Grayson
Powerful Coastal Storm Brings Snow, Extreme Cold, Wind and Blizzard Conditions to the East Coast View an interactive 3D visualization of GPM data from Winter Storm Grayson in STORM Event Viewer Mobile version Cold Artic air has been keeping the vast majority of the country east of the Rockies in the deep freeze over the past week. Now a powerful coastal storm is working its way up the East Coast bringing a mixture of snow, freezing rain, high winds and blizzard conditions from as far south as Florida all the way up into Maine with blizzard warnings in effect along the coast from North Carolina...

GPM Finds Heavy Rain In Short Lived Tropical Cyclone Hilda

Tropical cyclone HILDA formed very close to Australia's northwestern coast on December 27, 2017 at 1800 UTC and dissipated quickly as it crossed over land. The GPM core observatory satellite had a good view of the short lived tropical cyclone on December 27, 2017 at 2031 UTC. A red tropical storm symbol shows HILDA's approximate location when GPM passed above. The center of GPM's coverage was mainly east of HILDA's center of circulation. The intensity of rainfall in a large intense band of storms wrapping around the northeastern side of the tropical cyclone was measured by the satellite's

GPM Views Potential Australian Tropical Cyclone

On December 26, 2017 at 0806 UTC The GPM core observatory satellite satellite flew above northwestern Australia. GPM traveled over an area of convective thunderstorms in the Indian Ocean north of Australia's coast where a tropical cyclone is expected to develop. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that showed heavy precipitation in storms off the Australian coast. GPM's radar (DPR Ku Band) showed that a few extremely powerful convective storms northwest of the Dampier Land coast were dropping precipitation at a rate of greater

Tropical Storm Tembin Rainfall Added To IMERG Analysis

Tropical storm Tembin moved over the Philippine island of Mindanao on Friday December 22, 2017. Tembin added to the death and destruction already caused by tropical storm Kai-Tak that hit the central Philippines less than a week ago. Tembin brought heavy rainfall that resulted in more deadly flooding and landslides. At least eight deaths in the Philippines have been blamed on tropical storm Tembin. Rainfall totals in this accumulation analysis were updated to include IMERG data from both tropical storms Kai-Tak and Tembin. This rainfall analysis shows rainfall accumulation estimates from IMERG

Deadly Tropical Storm Kai-tak Examined With IMERG And GPM Satellite

Tropical storm KAI-TAK was nearly stationary at times as it drenched the Philippines during the past five days. The storm caused major flooding and landslides. Many homes, roads and bridges were reported destroyed by landslides. Over 30 deaths were caused by the slow-moving tropical storm. A rainfall accumulation analysis of tropical cyclone KAI-TAK was derived from NASA's Integrated Multi-satellitE Retrievals data (IMERG) for the period from December 13-18, 2017. Tropical cylone KAI-TAK's approximate locations and positions are shown overlaid in white on this analysis. IMERG data were used to
