Chicago, Illinois – Tornadoes, damaging winds, and flash flooding are all on the table for parts of Illinois and Indiana this afternoon as a line of storms intensifies over the region.
According to the National Weather Service Chicago, severe thunderstorms are expected mainly between 3 and 9 p.m. CDT, focusing on areas east and south of a Lostant-to-Gary line. These storms could bring 60+ mph wind gusts strong enough to down trees, while isolated tornadoes remain a real possibility. Torrential rainfall is also likely, increasing the risk of flash flooding in urban and low-lying areas.
Communities such as Joliet, Kankakee, Valparaiso, and Pontiac sit within the zone of highest concern. Travel along I-55, I-57, and I-80 could be hazardous during peak storm hours. Emergency managers urge residents to monitor alerts, secure outdoor items, and have multiple ways to receive warnings, especially if power is lost.
This afternoon’s system is tracking northeast at 30 mph and could bring quick-developing tornadoes with little warning. Residents should remain weather-aware through this evening.
Warnings remain in effect across northeastern Illinois and northwest Indiana through at least 9 p.m., with additional alerts possible if the storm intensifies.
