Showers and thunderstorms will continue working east across the area this morning. Frequent lightning and heavy rainfall are the main risks, with flash flooding possible in some areas of northeast Iowa, southeast Minnesota, and southwest Wisconsin where the heaviest rain occurs.
A Flash Flood Watch is in effect for parts of southeast Minnesota, northeast Iowa, and southwest Wisconsin through noon today. Heavy rainfall of 2 to 3 inches, with localized higher amounts, could cause flash flooding and river flooding in these areas, with the highest risk for those locations which received significant rains over the past week. Remember to never attempt to drive through flooded roads and always obey all road closures. Be especially cautious driving at night when it is harder to recognize flood dangers.
Here are some Flash Flood safety rules. If you live in northeast Iowa and southwest Wisconsin, be weather aware late tonight and Thursday morning.
Periods of showers and storms will gradually wind down this morning, with additional chances for rain arriving Friday and especially Saturday. Locally heavy rainfall through the weekend may lead to rises on rivers and some flooding.
