Milwaukee, WI – Wisconsin faces a significant flood risk this weekend as heavy rainfall and repeated thunderstorms are forecast to impact much of the state through Monday night. The National Weather Service Milwaukee/Sullivan warns that central and southern regions will experience the highest rainfall totals, creating hazardous conditions for travel and outdoor activities.
Heavy Rainfall Expected Across Central and Southern Wisconsin
Multiple rounds of storms will move across the state, bringing 1 inch or more of rain in many areas, with some locations receiving over 2 inches. The heaviest rainfall rates, potentially reaching 2 inches per hour, are expected during slow-moving storms between Saturday and Monday, increasing the risk of flash flooding in already saturated regions.
Forecast models indicate a 100% probability of at least 1 inch of rain in central locations such as Lone Rock, while Dodgeville, Portage, and Sauk City face mid- to high-90% chances. The likelihood for 2 inches or more is lower but still significant in areas including Wisconsin Dells and Lone Rock, where chances approach 70%.
Uncertainty in Storm Tracks Raises Flood Concerns
The National Weather Service cautions that small shifts in storm tracks can dramatically change the location of heaviest rainfall. Rainfall totals will depend heavily on the number of times storm complexes pass over the same areas, meaning flooding could occur in locations not initially predicted.
Residents are urged to monitor flood advisories, avoid driving through flooded roads, and take preventive measures such as moving important belongings from basements to higher ground.
Timing and Travel Impacts
The peak rainfall threat is expected overnight Saturday and Sunday, tapering off by Tuesday morning. As a frontal boundary dips into southern Wisconsin late Sunday, storm intensity is expected to maintain until the system exits early next week, creating hazardous travel conditions across the state.
