The NWS is continuing to survey the damage, and the number of confirmed tornadoes may increase as more data becomes available.

Why It's Important?

The tornadoes caused significant damage across Wisconsin, with at least 75 homes reported damaged or destroyed in Marathon County alone. Despite the extensive property damage, there were no reported injuries or fatalities. The storms also resulted in widespread power outages and downed trees, particularly in the town of Ringle. In addition to the tornadoes, severe thunderstorms and heavy rain led to flooding in Milwaukee, contributing to the city's rainiest April since at least 2000. Flood warnings remain in effect for several counties, with evacuation orders in place for low-lying areas.

What's Next?

The tornadoes occurred throughout the afternoon and evening of April 17, with the first tornado touching down in western Wisconsin around 3:27 p.m. and the last confirmed tornado occurring in Waukesha County at 7:52 p.m. The NWS continues to monitor the situation, and flood warnings are expected to remain in effect until at least April 23. Residents in affected areas should remain vigilant and follow any additional advisories issued by local authorities.

Beyond the Headlines

Residents in affected areas should stay informed through local news and official channels for updates on weather conditions and safety advisories. Those in flood-prone areas should be prepared to evacuate if necessary and avoid driving through flooded roads. It is important to have an emergency plan in place and to secure any loose outdoor items that could become projectiles in high winds.
