At least two tornadoes ripped through Dallas, Texas midday Tuesday, causing widespread destruction.

Weather forecasters described the storms as “large and extremely dangerous.” They have issued a tornado watch for Dallas through Tuesday evening local time, meaning that more dangerous weather could be on the way.

American Airlines canceled all flights at the Dallas-Forth Worth Airport for the rest of the day because of the threat of hail and lightning.

The twisters picked up large trucks and threw them to the ground. The tornadoes also destroyed homes as they tore through residential neighborhoods, but so far no casualties have been reported.
