Widespread strong thunderstorms with damaging winds and locally heavy rain are expected from the Upper Ohio Valley into the southern Mid-Atlantic today and portions of the central Appalachians and Carolinas on Saturday. Monsoonal moisture will bring a flash flooding threat to the Desert Southwest. Sweltering heat persists from the Plains to the southern Mid-Atlantic through tonight. Read More >

Overview

Record-setting rainfall of 6-12 inches (and more in a few areas) along the headwaters of the Kickapoo River near and north of Ontario, Wisconsin produced a major flood down the entire span of the river between August 28th and 30th, 2018. In most areas, this flood exceeded the previous record flood of June 9-10th, 2008, with new flood crest records being established in many areas. Please note that as of September 7th, 2018, we are still awaiting final flood crests from the United States Geological Survey for Ontario and La Farge, Wisconsin as those river gauges failed during the flood. Also, this information should be considered preliminary and could change if new data are received regarding the highest river levels.
