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...

GPM Finds Heavy Rain In Short Lived Tropical Cyclone Hilda

GPM Finds Heavy Rain In Short Lived Tropical Cyclone Hilda
Tropical cyclone HILDA formed very close to Australia's northwestern coast on December 27, 2017 at 1800 UTC and dissipated quickly as it crossed over land. The GPM core observatory satellite had a good view of the short lived tropical cyclone on December 27, 2017 at 2031 UTC. A red tropical storm symbol shows HILDA's approximate location when GPM passed above. The center of GPM's coverage was mainly east of HILDA's center of circulation. The intensity of rainfall in a large intense band of storms wrapping around the northeastern side of the tropical cyclone was measured by the satellite's

GPM Views Potential Australian Tropical Cyclone

GPM Views Potential Australian Tropical Cyclone
On December 26, 2017 at 0806 UTC The GPM core observatory satellite satellite flew above northwestern Australia. GPM traveled over an area of convective thunderstorms in the Indian Ocean north of Australia's coast where a tropical cyclone is expected to develop. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that showed heavy precipitation in storms off the Australian coast. GPM's radar (DPR Ku Band) showed that a few extremely powerful convective storms northwest of the Dampier Land coast were dropping precipitation at a rate of greater

Tropical Storm Tembin Rainfall Added To IMERG Analysis

Tropical Storm Tembin Rainfall Added To IMERG Analysis
Tropical storm Tembin moved over the Philippine island of Mindanao on Friday December 22, 2017. Tembin added to the death and destruction already caused by tropical storm Kai-Tak that hit the central Philippines less than a week ago. Tembin brought heavy rainfall that resulted in more deadly flooding and landslides. At least eight deaths in the Philippines have been blamed on tropical storm Tembin. Rainfall totals in this accumulation analysis were updated to include IMERG data from both tropical storms Kai-Tak and Tembin. This rainfall analysis shows rainfall accumulation estimates from IMERG

Deadly Tropical Storm Kai-tak Examined With IMERG And GPM Satellite

Deadly Tropical Storm Kai-tak Examined With IMERG And GPM Satellite
Tropical storm KAI-TAK was nearly stationary at times as it drenched the Philippines during the past five days. The storm caused major flooding and landslides. Many homes, roads and bridges were reported destroyed by landslides. Over 30 deaths were caused by the slow-moving tropical storm. A rainfall accumulation analysis of tropical cyclone KAI-TAK was derived from NASA's Integrated Multi-satellitE Retrievals data (IMERG) for the period from December 13-18, 2017. Tropical cylone KAI-TAK's approximate locations and positions are shown overlaid in white on this analysis. IMERG data were used to

GPM Sees Ockhi's Rain Reaching India's Western Coast

GPM Sees OCKHI's Rain Reaching India's Western Coast
NASA's GPM Core Observatory satellite passed over western India on December 5, 2017 at 0521 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed precipitation from dissipating tropical cyclone OCKHI reaching India's western coast. GPM's radar (DPR Ku band) indicated that rain was falling at a rate of over 101.6 mm (4 inches) per hour in a few storms near India's coast. OCKHI's low level center of circulation, shown with a red tropical cyclone symbol, was located well to the southwest of the storms that were moving onto India's western coast. This 3

Tropical Cyclone Ockhi's Rainfall Examined By GPM

Tropical Cyclone Ockhi's Rainfall Examined By GPM
On December 2, 1027 OCKHI became the first tropical cyclone of the year to form in the Arabian Sea. Fortunately for India the tropical cyclone remained off India's southwestern coast. OCKHI intensified to the equivalent of a category 3 hurricane on the Saffir-Simpson hurricane wind scale before it started to weaken. Vertical wind shear caused OCKHI to weaken as the tropical cyclone started moving north-northeastward toward India's Gulf of Khambhat. NASA's GPM Core Observatory satellite passed over tropical cyclone OCKHI on December 4, 2017 at 0616 UTC. The rainfall coverage shown here was
