Tornadoes that swept through the Dallas area caused substantial damage and at least 11 people died either from the storm or related traffic accidents. Dozens of people were injured in the storms as well.

It's the latest of a succession of freakish winter-weather events across the country that could include heavy snow and massive flooding Sunday from north Texas through eastern Oklahoma, eastern Kansas, western Arkansas and parts of Missouri. Days of tumultuous weather in the Southeast have led to 29 deaths overall — those in Texas plus 18 total in Mississippi, Alabama, Tennessee and Arkansas.

The full extent of damage in Texas isn't yet known, though it stretched over about a 40-mile-long area from 20 miles south of Dallas to northeast of the city. The storm blew the roofs off homes, mangled vehicles, damaged churches, downed power lines, toppled trees and caused natural gas lines to burst.

Garland Police Lt. Pedro Barineau said Sunday morning that eight people have died and 15 were injured in Garland, which is about 20 miles northeast of Dallas. That death toll went up by three since Saturday night.
