GPM Examines Weakening Tropical Cyclone Kenanga

GPM Examines Weakening Tropical Cyclone Kenanga
Tropical cyclone Kenanga has started to weaken as predicted. The GPM core observatory satellite had an excellent view of Kenanga on December 20, 2018 at 1454 UTC when the tropical cyclone's maximum sustained winds had decreased to about 90 kts (103.5 mph). That GPM pass also showed that the eye that was so prominent a day earlier had filled. Data collected by the satellite's Microwave Imager (GMI) and GPM's Dual-Frequency Precipitation Radar (DPR) instruments revealed through the overcast that powerful storms south of Kenanga's center of circulation were still producing very heavy rainfall

GPM IMERG Measures Hurricane Michaels Rainfall Accumulation

GPM IMERG Measures Hurricane Michaels Rainfall Accumulation
At least eleven deaths have now been attributed to deadly hurricane Micheal. Some casualties resulted not only from Micheal's destructive winds and storm surges but also from the blinding rain that Micheal produced as it battered states from Florida northeastward through Virginia. Today tropical storm Micheal is moving out over the Atlantic Ocean and has transitioned into a powerful extratropical storm. This animation using the GPM IMERG multi-satellite dataset shows the estimated total rainfall accumulation for #HurricaneMichael from 10/8/18 - 10/12/18. Learn more: https://t.co/aJuEp6o855 pic

IMERG Measures Flooding Rainfall In Deadly California Wildfire Areas

IMERG Measures Flooding Rainfall In Deadly California Wildfire Areas
Heavy precipitation has been falling in areas of California that were recently devastated by deadly wildfires. This flooding rainfall has resulted in evacuations in burn scarred areas such as Butte County where the deadly Camp Fire hit this month. Flash floods, debris flows and mudslides are now predicted in areas where deadly wildfires stripped away vegetation. On a positive note these Pacific storms are expected to dampen wildfires and replenish the Sierra Nevada snowpack. This snowpack is an important source of water for California's streams and rivers.

NASA's IMERG Used To Analyze Tropical Storm Usagi's Rainfall

NASA's IMERG Used To Analyze Tropical Storm Usagi's Rainfall
Usagi strengthened to hurricane intensity as it approached Vietnam from the South China Sea but weakened to tropical storm intensity when coming ashore. Very heavy rainfall and damaging winds accompanied tropical storm Usagi when it hit Vietnam's southern coast. More than 350 mm (14 inches) of rainfall was reported causing widespread flooding around Ho Chi Minh City. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used to show estimates of rainfall accumulation produced by Usagi as the tropical cyclone moved across the South China Sea into Southeast Asia. This IMERG

Tropical Cyclone Gaja's Rainfall Measured With IMERG

Tropical Cyclone Gaja's Rainfall Measured With IMERG
Tropical cyclone Gaja recently caused the deaths of at least 33 people in the southern India state of Tamil Nadu. Gaja's high wind and heavy rains caused landslides and building collapses. Gaja's maximum sustained winds had reached about 75kts (86 mph) when it hit southern India on Friday November 16, 2018. This meant that Gaja was the equivalent of a category one on the Saffir-Simpson hurricane wind scale. Today another tropical low is also moving over southern India and is expected to produce more heavy rainfall in the same area. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG)

Italy's Extreme Rainfall Examined With IMERG

Italy's Extreme Rainfall Examined With IMERG
During the past week a strong low-pressure system moving through southern Europe battered, drenched and flooded Italy. It caused flooding, landslides and other damage to large areas of the country. The deaths of at least 11 people have been attributed to this stormy weather. High winds knocked down many trees and heavy rainfall from these storms contributed to flooding in large areas of Italy. Venice was inundated when heavy rain fell and a surge of water from the Adriatic Sea was pushed into the city by the storm's very high winds. Data from various satellites, that cover most of the globe

GPM Examines Weaker Tropical Storm Yutu in the South China Sea

GPM Examines Weaker Tropical Storm Yutu in the South China Sea
Typhoon YUTU (known as Rosita in the Philippines) is now threatening the Philippine Island of Luzon. On October 24, 2018 YUTU devastated the northern Mariana Islands of Tinian and Saipan as a super typhoon. One death has been attributed to the typhoon in the Marianas with many structures including schools and hospitals being destroyed. Typhoon YUTU weakened as it moved toward the Philippines and had maximum sustained winds of about 90 kts (103.5 mph) when the GPM core observatory satellite passed above the Philippine Sea on October 29, 2018 at 0212 UTC. This rainfall analysis was developed

GPM Catches Typhoon Yutu Making Landfall

GPM Catches Typhoon Yutu Making Landfall
Friday, October 26, 2018
NASA's GPM Core observatory satellite captured an image of Super Typhoon Yutu when it flew over the powerful storm just as the center was striking the central Northern Mariana Islands north of Guam. Early Thursday, Oct. 25 local time, Super Typhoon Yutu crossed over the U.S. commonwealth of the Northern Mariana Islands. It was the equivalent of a Category 5 hurricane. The National Weather Service in Guam said it was the strongest storm to hit any part of the U.S. this year.

Dangerous Hurricane Willa Probed By GPM Satellite

Dangerous Hurricane Willa Probed By GPM Satellite
Hurricane Willa was moving northward toward the western coast of Mexico when the GPM core observatory passed above on October 21, 2018 at 1:51 PM MDT (1951 UTC). The hurricane had maximum sustained winds of about 95 mph (109 kts). Since then Willa has rapidly intensified and today has winds of 155 mph (135 kts) making it a dangerous category four on the Saffir-Simpson hurricane wind scale. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data showing that hurricane Willa and feeder bands were producing heavy rainfall over a large area. The

GPM Views Downgraded Hurricane Michael Soaking the Eastern U.S.

GPM Views Downgraded Hurricane Michael Soaking the Eastern U.S.
View fullscreen in STORM Event Viewer Hundreds of miles way from its landfall in Mexico Beach, Florida, Michael has been downgraded to a tropical storm, but it continues to pack a punch. Waterlogged regions of the Carolinas from Hurricane Florence are seeing trees toppled in the gusty winds, while rain falling in the Appalachian Mountains is leading to flash flooding and water rescues. Widespread power outages and flooding remain likely as the storm moves to the northeast through the rest of the day.
