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

The GPM core observatory satellite flew over stormy weather in the Midwest on Saturday February 24, 2018 at 1610 UTC (10:10 AM CST). Floods and very severe thunderstorms were developing with this slow moving storm complex. Later in the day tornadoes within these storms caused destruction and injuries in the states of Kentucky, Arkansas, Missouri and Tennessee. Tornadoes and flooding were blamed for at least four fatalities. Kentucky was particularly hard hit with Saturday evening tornadoes moving through southwestern Kentucky causing multiple injuries and at least three deaths. GPM's microwave

As predicted, the remnants of tropical cyclone GITA hit New Zealand on Tuesday (local time). GITA had transitioned to an extra-tropical low and was much weaker than when it hit Tonga last week. It still contained strong tropical strong force winds with occasionally heavy rainfall. New Zealand's South Island was the hardest hit. The northern end of of the South Island was in the right front quadrant of the tropical cyclone where the wind speeds around the center of circulation were increased by the low's speed of movement. Torrential rainfall led to flooding and landslides on the South Island

Tropical Cyclone Kelvin struck Northwestern Australia with winds reaching 54 knots as it crossed the Kimberley Coast. It brought flooding rains and damaging winds to the settlements and mining companies of the region. The storm intrigued meteorologists as it only developed a cloudless eye after making landfall, believed in part due to the heat flux generated by the warm desert the storm traveled over.
