Milwaukee, WI – Wisconsin drivers woke Tuesday to water-covered streets, with flash flooding slowing commutes across Milwaukee and Waukesha Counties. The National Weather Service reported heavy rainfall overnight, triggering a Flood Advisory that lasts until 1:15 a.m. Wednesday. Travelers should avoid low-lying roadways and never attempt to drive through standing water, especially along key routes such as I-94 and Highway 41.
According to the National Weather Service in Milwaukee/Sullivan, radar showed intense thunderstorms producing excessive rainfall late Monday. The heaviest totals hit Milwaukee’s western suburbs, including Wauwatosa, West Allis, and Brookfield, where poor drainage areas filled quickly. Minor flooding is expected to continue through Tuesday morning before conditions improve.
By Wednesday, drier air moves in, with only a slight chance of showers during the day. Skies clear further Thursday as sunshine and mild fall conditions take hold, offering southeast Wisconsin a stretch of calmer weather. Temperatures remain seasonable, topping out in the lower to mid-70s through Friday before cooling slightly this weekend.
Residents should monitor local advisories until Wednesday morning, especially in flood-prone neighborhoods. Officials stress preparing for detours and allowing extra travel time. With clearer skies on the way, this first week of fall offers a welcome break after a soggy start.
