At least 13 killed as tornadoes and severe weather pound South

At least 13 deaths have been reported in Alabama, Mississippi and Tennessee from a storm system that's spawned tornadoes and damaged homes as it moves across the South, threatening millions in its path, officials said.

As the storm hopscotched across a large swath of the U.S., the overall death toll was at least 30, with 13 killed Monday and 17 Sunday in a band stretching from Oklahoma to Alabama. Forecasts showed the storm continuing to move east early Tuesday, with Georgia and Alabama residents waking to sirens, howling wind and pounding rain.

Others found their loved ones missing and their homes pulverized early Tuesday. Along Mississippi Highway 397 on the eastern edge of Louisville, firefighters picked through the remains of mobile homes, searching for three people unaccounted for after a tornado tore through. Twenty firefighters linked hands and waded through an area where wood frame homes had also been heavily damaged. Rescue workers stepped gingerly over downed power lines and trees that were snapped in half and stripped of branches.
