A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
Flood Watch to include portions of southern Illinois...southwest Indiana and southeast Missouri, including the following areas, in southern Illinois, Alexander, Franklin, Hamilton, Jackson, Johnson, Pulaski, Saline, Union, White and Williamson. In southwest Indiana, Gibson and Pike. In southeast Missouri, Bollinger, Butler, Cape Girardeau, Carter, Perry MO, Ripley, Scott, Stoddard and Wayne MO.
From this evening through Sunday morning
A consistent signal for locally heavy rain is forecast, especially Saturday night into early Sunday morning. Storm total average rainfall is forecast to be up to 2 inches in the Watch area and, with thunderstorms forecast, localized higher totals to 3 inches or more are possible. This amount of cumulative rainfall will be falling on recently soaked grounds from melted snowfall, so the ability to soak in all this expected rainfall will be compromised and likely to cause flood issues.
