Flooding Closes Interstate 94 In Waukesha; Milwaukee Sewer Overflows

MILWAUKEE, WI — Excessive rain reached up to 7 inches in some parts of southeastern Wisconsin overnight, prompting a sewer overflow in Milwaukee and leaving Interstate 94 flooded in Waukesha, according to authorities.

The National Weather Service put a flood advisory into effect until 6 p.m. on Monday for Milwaukee, Waukesha and Racine Counties after excessive rainfall reached between 3-7 inches in some areas.

Interstate 94 was closed between County Road G and County Road T into Monday morning because of flooding, according to online updates from 511 Wisconsin. The roadway was closed just before 7 a.m. and as of 9:40 a.m. remains largely closed, 511 information showed.

Amid the heavy rainfall, Milwaukee Metropolitan Sewerage District began a combined sewer overflow around 11:15 p.m. on Sunday, meaning wastewater was discharged into local waterways to prevent basement backups. MMSD also issued a Water Drop Alert asking people in the area to reduce the amount of water they are using.

Amid flooding, the NWS recommends people take these safety precautions:

• "Never drive your car into water of unknown depth. Most flash flood deaths occur when people drive their vehicles into flood waters."
• Abandon your vehicle if it stalls and seek higher ground. Flood waters might rise quickly.
• Stay away from flooded areas. Water can continue to rise and can move very fast. A rapid stream can sweep you off your feet and sweep a vehicle downstream.
