Severe storms threaten millions across the US.

More than 60 million people from Colorado to the Carolinas are under threat for severe storms Sunday, including heavy rain, hail and tornadoes, with the lower Mississippi and Tennessee valleys at greatest threat. Multiple rounds of severe thunderstorms could hit the region this afternoon and evening, with damaging winds, large hail, and heavy rainfall as potential hazards. Parts of Georgia, Alabama, Tennessee, and the Carolinas can expect excessive rainfall due to the storm, possibly 1 to 3 inches Sunday. More than 100 storm reports came in Saturday across the lower Mississippi Valley and Arkansas, Louisiana, and Texas, most of which were damaging wind reports.
