Millions of Americans across Midwest placed under urgent tornado warning as Chicago braces for impact: 'Take cover now!'

Roughly five million people across the Midwest were placed under an urgent tornado warning as severe storms tear through the densely-populated Chicago area.

The National Weather Service issued tornado warnings for multiple counties in both Midwest states as extreme winds and heavy rain move through the region on Tuesday, causing flooding and blackouts.

'Heavy rainfall may hide this tornado. Do not wait to see or hear the tornado. TAKE COVER NOW!'

Meteorologist Max Velocity reported that weather stations in Illinois have registered wind gusts exceeding 130 mph.

He added that radar scans made it clear multiple tornadoes had likely touched down in northern Illinois, with the severe weather moving East into Indiana, Ohio and Michigan as well.

'This is an extremely dangerous situation. I cannot stress enough that you have to take shelter. Even if you are not under a tornado, you have to take shelter, even if you are under a severe thunderstorm warning,' Velocity said in a YouTube livestream following the storms.

Drivers in Illinois and Indiana were seen taking shelter under overpasses, which Velocity noted was a potentially deadly mistake, as winds actually get stronger and more dangerous under an overpass.

Torrential downpours and high winds were seen in Indiana at 12pm ET as the tornado warning stretched into Gary, Indiana, just 30 miles from Chicago. Meanwhile, the winds were so strong in Ohio, cars were being blown off the road.

NWS warned residents throughout the area to find somewhere indoors to hide even if you cannot actually see or hear a tornado forming.

'This cluster of thunderstorms is capable of producing tornadoes and widespread significant wind damage. Do not wait to see or hear the tornado. For your protection move to an interior room on the lowest floor of a building,' the agency wrote.

The widespread supercell, meaning a thunderstorm strong enough to create twisters, has also affected nearby states including Ohio, where roughly 180,000 customers have lost power.

According to PowerOutage.us, more than 300,000 customers have lost power in Indiana, and around 290,000 are in the dark in Illinois as of 1.40pm ET. Another 40,000 customers have lost power across Virginia and West Virginia combined.

Velocity said that he believed the Midwest was being hit by a derecho, a widespread and long-lived windstorm created by fast-moving line of thunderstorms.

This type of storm brings damaging straight-line winds that can exceed 100 mph over a very large area, sometimes even for hundreds of miles.

The heavy rains have also triggered a potentially deadly flash flood warning in Chicago through Tuesday afternoon.

Roadway surveillance cameras being viewed by Velocity caught the dangerous winds in Columbus, Ohio flipping over a moving car as it drove along Weber Road.

'For 2026, Tornado Alley is literally Illinois,' Velocity declared.

Studies have supported the idea of the famous hotspot of extreme weather shifting from the southern US to the Midwest and Great Lakes regions.

The old hotspot in Texas, Oklahoma, Kansas and Nebraska has now been threatening more Americans each year in states such as Mississippi, Alabama, Tennessee, Kentucky, Arkansas, Illinois, Indiana, Missouri and Iowa.

A 2024 study in the Journal of Applied Meteorology discovered a clear shift in the states being hit by tornadoes after 1985, with more twisters landing outside of  the traditional Tornado Alley.

Between 1951 and 1985, the highest number of tornadoes were recorded in the classic Great Plains, in states such as Oklahoma, Kansas and northern Texas.

Since then, researchers found Tornado Alley has seen annual twister reports drop by up to 40 percent in certain areas. Meanwhile, tornadoes have surged by 25 percent in Mississippi, Tennessee and parts of the Ohio Valley.

While officials have not made any determinations on how many tornadoes touched down on Tuesday, residents throughout the Great Lakes region shared pictured on social media of the high winds bringing down trees, damaging homes and even sending branches into powerlines and starting fires.

AccuWeather noted that the thunderstorms are expected to stretch into Wednesday, reaching parts of coastal Virginia, Tennessee and the Carolinas.

A massive area from Chicago to Pittsburgh is expected to see anywhere from two to eight inches of rain by Thursday.
