GPM Sees Tropical Cyclone Berguitta Battering Mauritius

GPM Sees Tropical Cyclone BERGUITTA Battering Mauritius
Tropical cyclone BERGUITTA was moving very close to the eastern side of the island of Mauritius when the GPM core observatory satellite passed above on January 18, 2018 at 0528Z (9:28 AM local time). This meant that the most destructive section of tropical cyclone BERGUITTA was passing very close to the eastern side of Mauritius. For this reason the eastern side of Mauritius would be expected to have had the highest winds, seas, and storm surge from BERGUITTA. The tropical cyclone was passing a little farther to the east of the island of Reunion. Data collected by GPM's Microwave Imager (GMI)

GPM Sees Tropical Cyclone Berguitta Bearing Down On Mauritius

GPM Sees Tropical Cyclone BERGUITTA Bearing Down On Mauritius
The GPM core observatory satellite passed over the southwest Indian Ocean on January 16, 2018 at 1856 UTC. GPM showed that heavy rainfall within tropical cyclone BERGUITTA was moving closer to the islands of Reunion and Mauritius. GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments found that powerful storms northeast of Mauritius were dropping rain at a rate greater than 54 mm (2.1 inches) per hour. A 3-D view of Storm top heights within tropical cyclone BERGUITTA was made possible with GPM's radar (DPR ku Band). Those 3-D scans through the eastern side of

IMERG Reveals Rainfall Rates With Tropical Cyclone Berguitta

IMERG Reveals Rainfall Rates With Tropical Cyclone BERGUITTA
Tropical cyclone BERGUITTA formed in the southwestern Indian Ocean northeast of the islands of La Reunion and Mauritius on January 12, 2018. BERGUITTA is now moving toward the southwest and threatening the islands. Early on January 16,2018 BERGUITTA had maximum sustained winds estimated at 100 kts (115 mph). This means that BERGUITTA was the equivalent of a category three hurricane on the Saffir-Simpson hurricane wind scale. Later in the day BERGUITTA's maximum sustained wind speeds were estimated at 85 kts (98 mph) with gust to 105 kts (121 mph). On January 16, 2018 at 1200Z tropical cyclone

Heavy Rainfall Leads To Deadly California Mudslides

Heavy Rainfall Leads To Deadly California Mudslides
Winter rains falling on recently burned ground triggered deadly mudslides near Santa Barbara, California on the 9th of January. The potential for landslides is shown above. It was generated by the global Landslide Hazard Assessment for Situational Awareness (LHASA) model, a model that combines GPM precipitation data with a global landslide susceptibility map. LHASA gives a broad overview of landslide hazard in nearly real time, but site-specific information should be obtained prior to emergency operations or building projects. At least 15 residents of southern California have been killed by

Tropical Cyclone Ava's Disastrous Rainfall Measured With IMERG

Tropical Cyclone Ava's Disastrous Rainfall Measured With IMERG
Tropical cyclone Ava dropped extremely heavy rainfall over Madagascar as it passed over the eastern side of the island country from January 5-6, 2018. Ava's drenching rainfall caused flooding and landslides which resulted in the deaths of at least 29 people. An estimated 80,000 people on Madagascar were affected by the tropical cyclone. This rainfall analysis was produced by accumulating rainfall that fell near Madagascar during the period from January 2-8, 2018. These IMERG estimates showed the locations of extreme rainfall totals during the period when tropical cyclone Ava was in Madagascar

Powerful Tropical Cyclone Irving Examined With GPM

Powerful Tropical Cyclone Irving Examined With GPM
Tropical cyclone Irving formed in the South Indian Ocean on January 6, 2018. Irving posed no threat to land because it orgininated over the open ocean far to the west of Australia. GPM's core observatory satellite had an excellent view of Irving's eye on January 2018 at 0706Z. The well defined rainfall patterns within Irving were clearly shown by GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) data. Very heavy rainfall was shown in the western side of Irving's large eye wall. GPM's Radar (DPR Ku Band) found rain in that side of the tropical cyclone falling at a rate

Tropical Cyclone Ava Viewed By GPM

Tropical Cyclone Ava Viewed By GPM
Tropical cyclone AVA formed in the southeast Indian Ocean northeast of Madagascar on January 2, 2018. AVA became increasingly powerful and approached the eastern coast of Madagascar with maximum sustained winds estimated to be greater than 90 kts (103.5 mph). AVA has been interacting with land and wind speeds near Tamatave, Madagascar have been reported to be 70 kts (80.5 mph). The Joint Typhoon Warning Center (JTWC) predicts that tropical cyclone AVA will move to the south along Madagascar's eastern coast for a day or so and then return to the Indian Ocean. Very heavy rainfall is expected to

Powerful Coastal Storm Brings Snow, Extreme Cold, Wind and Blizzard Conditions to the East Coast View an interactive 3D visualization of GPM data from Winter Storm Grayson in STORM Event Viewer Mobile version Cold Artic air has been keeping the vast majority of the country east of the Rockies in the deep freeze over the past week. Now a powerful coastal storm is working its way up the East Coast bringing a mixture of snow, freezing rain, high winds and blizzard conditions from as far south as Florida all the way up into Maine with blizzard warnings in effect along the coast from North Carolina...
