Communities across the United States -- from small towns to big cities -- were on alert for tornadoes on Wednesday, as a major storm system sweeps through areas still reeling from devastating twisters.
There were an unspecified number of injuries and fatalities confirmed in Missouri's Bollinger County after a tornado hit the Glenallen area, according to the Missouri State Highway Patrol.
At least nine other tornadoes had already been reported across Iowa and Illinois, including a "large and extremely dangerous tornado" that touched down near Canton, Illinois, on Tuesday evening, according to the National Weather Service.
On Wednesday morning, the National Weather Service issued a tornado watch for parts of Texas, Oklahoma, Arkansas, Missouri, Illinois, Michigan, Indiana and Ohio.
As the storm continues to move east, severe weather is in the forecast for a vast area -- from western Texas to western New York.
