Flood warning: Thunderstorms and heavy rain causes Milwaukee freeway and highway closures

The Mayor of Milwaukee warned residents of the impact of the weather.

Milwaukee residents have been hit by thunderstorms and heavy rain. Mayor Cavalier Johnson took to Facebook to warn people and said: “Severe weather means one thing, safety first. Seek shelter and monitor weather alerts from trusted sources and avoid travel. Check on your neighbors, family and friends to make sure they have a plan for staying safe.”

The latest update from the National Weather Service reads: “Moderate to heavy rain has ended early this morning, but areas of standing flood water remain over parts of the area hit hardest last evening and overnight.

“Standing water impacts have focused mainly in urban and low-lying areas, with multiple reports of road closures. A flood warning has been issued for parts of southeast Wisconsin until 1 PM as flood waters continue to work through local drainage systems. Heed any road closures during the morning commute, and never drive through flooded roadways.”

The website TMJ4 reported that “Near Timmerman Airport at 97th Street and Hampton Avenue, rapidly rising water trapped multiple drivers. At least five vehicles became stuck in the floodwaters. TMJ4's Mike Beiermeister called 911 after finding four people inside one of the submerged cars. Emergency services responded, and all drivers and passengers were able to get out safely.”

According to reports, parts of Interstate 43, Interstate 94 and Wisconsin Highway 175 were shuttered for several hours due to flooding. Only a day ago, NationalWorld reported on a tornado warning being put in place for the counties of Ozaukee, Milwaukee, Walworth, Racine and Waukesha in Wisconsin. The Facebook page for the City of Whitewater wrote: “ WISCONSIN TORNADO DRILL — THIS THURSDAY!
