Tropical cyclone Josie didn't make landfall in Fiji but it's heavy rainfall resulted in deadly flooding. Approximate locations of tropical cyclone Josie, as it moved close to Fiji, are shown overlaid in white. Josie's clockwise circulation streamed moisture over Fiji causing flooding that led to the deaths of at least four people. This rainfall accumulation analysis used Integrated Multi-satellitE Retrievals for GPM (IMERG) data. Those data are generated by NASA's Precipitation Processing System every half hour within about 6 hours from when data are acquired. IMERG data are acquired from the

Tropical storm JELAWAT intensified as expected and was upgraded to typhoon JELAWAT yesterday. Today JELAWAT has continued to rapidly intensify and maximum sustained wind speeds in the typhoon were estimated at 115 kts (132 mph). The GPM core observatory satellite had an excellent view of rapidly intensifying tropical storm JELAWAT on March 29, 2018 at 1546 UTC. JELAWAT had wind speeds of about 60 kts (69 mph) when GPM passed over head. An eye hadn't formed yet but rain bands were wrapping around JELAWAT's well established center of circulation. GPM's radar (DPR Ku Band) revealed that rain was

The GPM core observatory satellite flew almost directly above large intensifying tropical storm JELAWAT on March 28, 2018 at 0510 UTC. Rainfall measurements shown here were derived from data collected by GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments. These satellite instruments provided excellent coverage of JELAWAT's precipitation. GPM's Radar (DPR Ku Band) swath included exceptionally powerful storms within a large intense feeder band that was wrapping around the eastern side of the tropical storm. GPM's DPR revealed that these strong convective storms

Tropical Cyclone NORA produced heavy rainfall when it came ashore in northwestern Queensland on March 24, 2018 (GMT). NORA's peak intensity of 95 kts (109 mph) was reached when the tropical cyclone was located in the central northern Gulf Of Carpentaria. Winds had decreased slightly to 90 kts (104 mph) by landfall. The Australian Bureau of Meteorology (BOM) reported that NORA produced over 110 mm (4.3 inches) of rain in 24 hours. Flooding, landslides, lost electrical power, and structural damage were also a companion of the tropical cyclone's arrival. After landfall NORA weakened but the

Intensifying tropical cyclone NORA has been moving southeastward into the Gulf of Carpentaria since it formed in the Arafura Sea north-northeast of Darwin,Australia. The Joint Typhoon Warning Center (JTWC) issued it's first warning for Tropical cyclone NORA on March 22, 2018 at 0900Z. After that NORA's winds increased to over 65 kts (75 mph). That means that today NORA became the equivalent of a category one hurricane on the Saffir-Simpson hurricane wind scale. The GPM core observatory satellite scanned tropical cyclone NORAas it passed above on March 22, 2018 at 1847 UTC. GPM's Microwave
