A line of severe storms moving across the Midwest left death and destruction in its wake early today.

The storms moved through Kansas and Missouri overnight, destroying one trailer park and leaving at least one dead in Buffalo, Mo.

The hardest hit area is Harrisburg, Ill., where authorities say at least six people have been killed after what is presumed to be a tornado raked the town before dawn. (Note: in situations such as this, details such as the number of people killed and injured change as more information comes in. We will be updating this post.)

The National Weather Service says the storm system will very quickly make its way east, and more tornadoes are expected.

The NWS says these are the areas to watch through the evening:

— Northern Alabama

— Northern Georgia

— Southern and Eastern Kentucky

— Northern Mississippi

— Western North Carolina

— Much of Tennessee
