Hurricane Florence Makes Landfall, Brings Torrential Rains and Record Flooding to the Carolinas

Over the weekend #HurricaneFlorence brought torrential rains and record flooding to the Carolinas. This GPM IMERG visualization shows storm-total accumulated rainfall on the left for 9/12/18 - 9/17/18 vs. a sequence of 3-hour accumulations on the right — NASA Precipitation (@NASARain) September 17, 2018 After making its way across the Atlantic, Florence, a once powerful Category 4 hurricane with maximum sustained winds reported at 140 mph by the National Hurricane Center (NHC), finally made landfall early Friday morning at around 7:15 am EDT

GPM Observes Dangerous Super Typhoon Heading Toward The Philippines

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

GPM Probes Tropical Storm Isaac

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

GPM Views Super Typhoon Mangkhut Moving Towards the Coast of China

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

GPM Sees Heavy Rain In Menacing Hurricane Florence

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's Rainfall Measured With IMERG

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

GPM IMERG Adds Up Heavy Rains from Typhoon Jebi

Typhoon Jebi brought flooding to Japan and NASA’s IMERG estimated rainfall over the country and the surrounding region for a one-week period. The above image shows accumulated IMERG rainfall estimates over Japan and the surrounding region for the 1-week period from August 29 to Sept. 5, 2018 show rainfall amounts on the order of 100 mm (~4 inches, shown in red) or more covering much of the main island of Honshu and Shikoku in the south. Much of the band of rain oriented east-west across central Japan was due to a frontal system that brought rain to the area before Jebi made landfall. Super

GPM Sees Hurricane Florence Swirling In The Central Atlantic

Hurricane FLORENCE became more powerful over the past few days while moving through the central Atlantic Ocean. Wind speeds increased from tropical storm force to hurricane force on Tuesday. FLORENCE's maximum sustained winds were about 85 kts (98 mph) early today making it a category two hurricane on the Saffir-Simpson Hurricane wind scale. Hurricane FLORENCE is being steered toward the northwest by the Atlantic subtropical ridge. Early next week the National Hurricane Center (NHC) predicts that hurricane FLORENCE will have moved to a location southeast of Bermuda. The GPM core observatory

GPM Views Super Typhoon Jebi Twice

UPDATE 8/31/18 View Fullscreen in STORM Event Viewer Having peaked in intensity, Typhoon Jebi is a Category 5 Super Typhoon with maximum winds estimated around 142 knots. It is beginning an eyewall replacement cycle with a gap between the outer and inner eyewalls appearing somewhat in the DPR. The storm's strength is expected to fluctuate but remain well above Category 3 for the next two days before it turns northward toward Japan. It will likely have widespread impacts on Southern Honshu in around 4 days time, an area that has already struggled with rainfall, typhoons, and intense heat this

GPM Sees Tropical Cyclone Jebi Threaten Japan

Japan has been afflicted by several tropical cyclones and other extreme weather this summer. The Joint Typhoon Warning Center (JTWC) predicts that yet another typhoon called JEBI will be approaching the main islands of Japan early next week. Warm ocean temperatures and low vertical wind shear are providing a favorable environment for JEBI's intensification. The JTWC predicts that the typhoon will have peak sustained winds of 115 kts (132 mph) as it moves over the northern Pacific Ocean toward Japan next week. The GPM core observatory satellite passed above on August 28, 2018 at 1816 UTC when
