At least 11 people died and dozens were injured in strong tornadoes that swept through the Dallas area and caused substantial damage this weekend.

It was the latest of a succession of powerful weather events across the country, from heavy snow in New Mexico, west Texas and the Oklahoma Panhandle to flash flooding in parts of the Plains and Midwest.

The weather service said an EF-4 tornado, which is the second-most powerful with winds up to more than 200 mph, hit the community at about 6:45 p.m. Saturday. It was near the intersection of Interstate 30 and George Bush Turnpike, which is a major route in the region.

In the nearby town of Rowlett, City Manager Brian Funderburk said Sunday morning that 23 people were injured, but that there were no deaths and no reports of missing people.

The weather service said damage indicated it was likely an EF-3 tornado, which has winds up to 165 mph.

Three other people died in Collin County, about 45 miles northeast of Dallas, according to sheriff’s deputy Chris Havey, although the circumstances were not immediately clear.
