Heavy Rain and Thunderstorms in the Mississippi Valley; Flooding Continues Along the East Coast of Florida

A cold front approaching the Mississippi Valley will bring heavy rainfall and isolated severe thunderstorms to the region. Thunderstorms will have the potential to produce isolated severe wind gusts and perhaps a brief tornado or two. Significant river flooding is forecast along the St. John’s and the Peace rivers in Florida through the end of the week as flood waters will be slow to recede. Read More >

Graphical HWO - Flash Flooding Threat

This graphic shows the expected coverage of any potential flash flooding within the threatened area.

For example, a yellow shade (corresponding to the "Isolated" category) might reflect the possibility of an isolated thunderstorm that produces enough heavy rain to cause flash flooding within the shaded area. Conversely, a red color (or "Widespread" category) covering several counties would reflect a larger area of heavy rain that could cause flash flooding across multiple areas in those counties.
