Indianapolis, Indiana – A fast-moving line of storms could shut down major highways across the Midwest tonight as wind gusts up to 60 mph threaten to knock down trees and scatter debris across roadways through 1 a.m. Monday.
According to the National Weather Service Storm Prediction Center, more than 35 million people across 125 counties in Illinois, Indiana, and Ohio are under Severe Thunderstorm Watches. Storms are organizing into a line expected to sweep east across key corridors including I-70, I-65, I-71, and I-75.
The primary hazard is damaging straight-line winds strong enough to snap tree limbs and block roads within minutes. Cities including Indianapolis, Columbus, Cincinnati, Dayton, and Evansville are all in the highest impact zone, where travel could become dangerous during peak evening and overnight hours.
In Illinois, routes near Carbondale, Marion, and Effingham may see sudden visibility drops and debris. Across Indiana and Ohio, fallen branches and localized outages could create chain-reaction slowdowns on interstates and secondary roads.
Drivers should avoid unnecessary travel, especially during heavy rain and high winds, and never drive through debris-covered roads. Residents should prepare for possible power outages and rapidly changing conditions.
The most intense impacts will continue through 1 a.m., with additional warnings likely as the storm line pushes east across the region.
