Deadly tornadoes wreak havoc across multiple US states.

More than 45 million people from Dallas to Milwaukee are under risk of severe weather, including rare and dangerous overnight tornadoes and damaging winds. The next major tornado event is forecasted Tuesday afternoon through Wednesday morning, with dangerous nighttime tornadoes possible. Some states face the threat of tornadoes and hail, while others will be dealing with an increased fire danger as very dry brush, low humidity levels, and gusty winds converge to create prime conditions for wildfires. Over a million people are under an "extremely critical" risk of fire weather, and more than 50 million people are under high wind alerts.
