The GPM core observatory satellite had a fairly good look at powerful tropical cyclone HOLA on March 8, 2018 at 0812 UTC. HOLA was located northeast of New Caledonia with maximum sustained winds of about 95 kts (~ 105 mph). The rainfall in this image was derived from data received by GPM's Microwave Imager (GMI) and Dual Frequency Precipitation Radar (DPR) instruments. GPM's GMI provided the best coverage of the tropical cyclone. GMI data indicated that storms within HOLA were dropping rain at a rate of greater than 49 mm (1.9 inches) per hour in the southeast quadrant of the tropical cyclone

On March 6, 2018 at 0825 UTC the GPM core observatory satellite flew above a forming tropical cyclone in the southern Pacific Ocean just east of Vanuatu. GPM's Dual Frequency Precipitation Radar (DPR) scanned storms in the center of forming tropical cyclone 12P's circulation. This view by GPM's DPR revealed that convective storms were dropping extremely heavy rainfall on the eastern edge of the forming tropical cyclone's low level center. DPR indicated that rain was falling at a rate of over 241 mm (9.5 inches) per hour in this area. The use of GPM satellite's radar data enabled this 3-D view

Tropical cyclone DUMAZILE formed east of Madagascar on March 3, 2018. Since then the tropical cyclone has been causing flooding as the tropical cyclone moves parallel to Madagascar's eastern coast. The clockwise rotation of the tropical cyclone has been transporting bands of rain onto Madagascar. Over 210 mm (8.3 inches) of precipitation was reported along the northeastern coast of Madagascar. The GPM core observatory satellite passed over eastern Madagascar on March 3, 2018 at 1710Z. Tropical cyclone DUMAZILE was located in the Indian Ocean east of northeastern Madagascar. The tropical

Early in the morning of March 2nd 2018 the GPM satellite flew over the "Nor'easter" winter storm that is battering the eastern U.S. with damaging winds, rain, snow, and hail.

Today NOAA's National Weather Service has issued flood advisories and flood warnings for large areas of Arkansas and Tennessee. Large parts of the Ohio Valley and Mississippi valley have received flooding rainfall during the past week. Arkansas has seen more rain than any other state. Life threatening flood conditions have resulted from over 10 inches of rain falling in extensive areas of central Arkansas. The GPM core observatory satellite had an excellent view of the storms that were producing flooding rainfall in Arkansas when it flew above the state on Wednesday February 28, 2018 at 11:15
