At least two tornadoes violently spun through the Dallas-Forth Worth area, collapsing roofs, ripping down power lines and tossing trailers around like toys, authorities said Tuesday.

The National Weather Service said 'considerable damage' had been reported near Cleburne, south of Fort Worth, and Lancaster, south of Dallas. Local television footage showed overturned and smashed semi-trailers on the ground in the southern portion of Dallas County. 'Obviously we're going to have a lot of assessments to make when this is done,' Dallas County spokeswoman Maria Arita said.
