The deadly storms that ravaged much of the South and Midwest this weekend are heading east today. At least 36 people have died across Missouri, Arkansas, Texas, Oklahoma, Kansas, Alabama and Mississippi as powerful storm systems swept through the Midwest and South.

Millions of Americans across the country are on alert for a severe weather outbreak as violent, long-track tornadoes with damaging winds of up to 80 mph and large hail are expected across the Midwest and South with the cross-country storm moving east.

At least 30 people died as violent weather swept the country on Friday and Saturday, and the threat isn't over.
