More than 77 million people from the Midwest to the Southern Plains were under some form of tornado warning on Wednesday after multiple apparent twisters caused extensive damage in Illinois and Indiana. Northern Illinois remains the highest risk, with a "moderate" tornado warning for 2 million people in cities south and east of Chicago, including Joliet, Peoria, and Bloomington.

Why it matters

Severe weather events like tornadoes and storms can cause significant damage to homes, infrastructure, and disrupt power, creating dangerous conditions for residents. The Midwest is prone to these types of weather patterns, and warnings help communities prepare and take shelter when needed.

More than 12,000 energy customers were without power across the Midwest and 23,000 across the Great Lakes region on Wednesday morning.
