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.

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.

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.

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.

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.

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.
