GPM IMERG Measures Rainfall Accumulation from Hurricane Dorian in the Caribbean

Hurricane Dorian is packing heavy rain as it moves toward the Bahamas as predicted by NOAA’s NHC or National Hurricane Center. NASA's GPM mission recently analyzed the storm and found heavy rainfall in the storm as it passed through the Caribbean. This image shows estimated rainfall accumulations for the region affected by Hurricane Dorian over the 24 hour period of Aug.27 11:59 UTC to Aug. 28 11:59 UTC. The imagery was generated using the Integrated Multi-satEllite Retrievals for GPM (IMERG) “early run” product. The data indicates that up to 120 mm (4.72 inches) of rainfall accumulated in

IMERG Measures Flooding Rainfall in India

In early August 2019 a depression formed in the Bay of Bengal that moved over India contributing to heavy rainfall on India's west coast. NASA's satellite data analysis suggests that from August 5 though 11, two feet of rain fell in some places. This estimate is from the GPM-based realtime multi-satellite algorithm called IMERG, which is run at NASA Goddard. Credit: Owen Kelley (NASA GSFC)

Hurricane Barry Makes Landfall in Louisiana

UPDATE 7/17/19: This GPM IMERG animation shows rainfall accumulations from #HurricaneBarry in the Gulf of Mexico from July 11-16, 2019.

The

GPM Sees Developing Tropical Storm Barry in the Gulf of Mexico

NASA / JAXA’s GPM Core Observatory passed over developing Tropical Depression 2 (which was upgraded to Tropical Storm Barry later in the morning) in the Gulf of Mexico the morning of July 11th 2019 at 8:26am CT, capturing estimates of rainfall rates within the storm. The first image shows rainfall rates collected by GPM’s Microwave Imager, while the second image shows 3D rainfall rates within the atmospheric column from GPM’s Dual-frequency Precipitation Radar (DPR). The DPR measured storm top heights as high as 18 km, which is extremely high and indicative of intense thunderstorm activity

GPM Flies Over Flooding Rainfall in Washington DC

Washington DC experienced extreme rainfall the morning of July 8th, 2019 when a cluster of slow-moving thunderstorms moving through the area tapped into a very moist airmass to produce extremely heavy rains, which resulted in flash flooding throughout the region. The storms were triggered by a nearby frontal boundary. The GPM Core Observatory passed over this storm system at 8:51am ET, with its Dual-frequency Precipitation Radar measuring rainfall rates in excess of 100 mm/hr in some areas. Reagan National Airport (DCA) also reported receiving 80 mm of rainfall in one hour, corroborating the

NASA Reveals Heavy Rainfall in Tropical Cyclone Fani

Satellite data revealed heavy rainfall in powerful Tropical Cyclone Fani before it made landfall in northeastern India. Fani brought that soaking rain to the region and continues to drop heavy rainfall on May 3, as it moves toward Bangladesh. NASA’s GPM or Global Precipitation Measurement mission satellite provides information on precipitation from its orbit in space. On May 1 at 7:56 a.m. EDT (1156 UTC), the GPM Core Observatory captured an overpass of the powerful storm as it continued strengthening and moving toward landfall. A 3D image and a color-enhanced rainfall image were created at

GPM Flies Over Developing Tropical Storm Idai Twice

Intense Tropical Cyclone Idai started as a tropical depression on the 4th of March, 2019, off the coast of Mozambique. After making landfall over Mozambique it turned back over the Mozambique Channel and strengthened to become a tropical cyclone on the 10th of March. The GPM satellite captured the cyclone with both the GPM Microwave Imager (GMI) and the Dual-frequency Precipitation Radar (DPR) on the 11th of March at 04:36 UTC when the storm was in the middle on the Mozambique Channel. The DPR captured a well-developed eye, seen at the center of the image. It flew over the storm once again at

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

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

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.
