100 million people throughout the US were expected to be hit with severe weather on Thursday night and Friday.
According to the National Weather Service, damaging wind gusts and possible hail storms are also expected.
CNN reports that the storm system will then fan out to the Ohio Valley and East Coast, hence affecting a particularly large number of people.
The Gulf Coast has already been hit with severe weather this year, including a batch of tornadoes through Mississippi just last week, and a string of tornadoes in Alabama that killed 23 last month.
