View fullscreen in STORM Event Viewer Once a Category 5 Super Typhoon, Trami has become rooted in place due to a lack of steering flow. This has caused the storm to deplete the warm waters beneath it and it has since weakened to a Category 2 with maximum winds of 90 knots. It maintains a broad eye and once it begins moving again, is likely to reintensify at least somewhat as it zooms northeastward over the Ryukyu Islands and into the southern coast of Japan. Wind impacts are likely to be exacerbated by its forward speed and current forecasts expect it to have widespread impacts in a region

The GMI overflight here shows a clear center of circulation with much of the intense convection on the south side of Hurricane Rosa, a Category 1 storm with winds of 75 knots. It is expected to continue intensifying over the next couple days before it runs into strong shear and cooler waters off the Baja California coast. Forecasts suggest it will make landfall in Northern Baja as a tropical storm, with its primary impacts being heavy rainfall and flash flooding over the Desert Southwest.

The GPM core observatory satellite probed super typhoon TRAMI when it traveled above the northwestern Pacific Ocean on September 24, 2018 at 1203 UTC. At that time TRAMI had maximum sustained winds estimated at 130 kts (150 mph). This image shows rainfall measurements that were made using data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments. GPM's GMI showed the locations of extremely heavy rainfall in the super typhoon's well defined circular eye. GPM's radar (DPR Ku Band) coverage was limited because it's swath only included storms on the

#NASA's GPM IMERG data product was used to estimate the devastating heavy rainfall that fell on China and the Philippines from #TyphoonMangkhut.

Over the weekend #HurricaneFlorence brought torrential rains and record flooding to the Carolinas.

The GPM core observatory satellite has recently provided very useful information about super typhoon MANGKHUT in the western Pacific Ocean. A few days ago MANGHUT battered the Marianas Islands. MANGKHUT's destructive winds pounded the island of GUAM causing power outages and it's extremely heavy rainfall caused flash floods. The GPM core observatory satellite passed over super typhoon MANGKHUT on September 11, 2018 at 0407 UTC when it was west of GUAM. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) collected data showing that MANGKHUT was a large and very well

Hurricane Florence, tropical storm ISAAC and hurricane Helene are currently active in the Atlantic Ocean. Tropical storm ISAAC is the next tropical cyclone to affect the western Atlantic. It is moving westward toward the Leeward and Windward Islands. The National Hurricane Center (NHC) predicts that ISAAC will pass through the Leeward and Windward Islands and move into the Caribbean Sea over the next few days. The NHC predicts that ISAAC will weaken as it encounters moderate vertical shear and nearby dry air. The GPM core observatory satellite had an excellent view of tropical storm ISAAC on

View Fullscreen in STORM Event Viewer A day after rolling through the southern Mariana Islands, causing wind and water damage to Guam and other nearby islands, Mangkhut has intensified into a Category 4 Super Typhoon with winds of 135 knots. With favorable conditions and the warm waters of the Philippine Sea, it is expected to maintain much of this intensity as it continues to track west-northwestward. Currently models anticipate Mangkhut to pass between the Phillipines and Taiwan, weakening slightly due to interaction with the two islands, before continuing toward the Southeastern Chinese

Last Friday Florence was a sheared tropical storm but on Saturday vertical shear lessened and Florence started to get better organized. Today hurricane Florence is rapidly strengthening. The National Hurricane Center (NHC) predicts that Florence will be a major hurricane with maximum sustained winds peaking at 130 kts (~150 mph) on Wednesday when it is over the open Atlantic well southwest of Bermuda. The NHC predicts that Florence's winds will decrease slightly to 125 kts (144 mph) as the hurricane threatens the southeastern United States on Thursday September 13, 2018. OVERPASS 9/9/18: View

Tropical Storm Gordon became the seventh named system of the 2018 Atlantic hurricane season on Monday September 3, 2018. GORDON became more intense as it moved through the eastern Gulf Of Mexico but didn't quite make it to hurricane force before landfall. GORDON was a strong tropical storm with winds of about 70 mph (~ 61 kts) when it hit southeastern Mississippi on September 5, 2018. GORDON continued to produce rainfall as it moved inland. Weakening GORDON spawned a tornado near Picayune, Mississippi on Thursday September 6, 2018. Today, tropical depression GORDON is still responsible for
