The tornado and accompanying severe weather have caused widespread damage in affected areas, including Appleton, Neenah, Oshkosh, and Menasha. Downed trees, power lines, and debris have blocked roadways, hindering emergency response efforts. Power outages have impacted over 400,000 customers, and travel in Menasha is restricted to emergencies only. The severe thunderstorms pose additional risks, including large hail, destructive winds, and flash flooding, particularly in northeastern Illinois and southeastern Wisconsin. Residents in the risk area, which extends to western Ohio, should remain vigilant as more storms are expected.
