There have been at least six people killed and seven missing after a tornado passed through north-central Teas on Wednesday evening.

Reuters reported that authorities warn the death toll could rise. The storm struck early evening around dusk and uprooted trees and ruined homes in at least four counties near Dallas-Fort Worth. One of the hardest hit was Granbury which is 35 miles southwest of Dallas-Fort Worth.

"The main concern is life safety and finding any victims that still need our help," Hood County Sheriff Roger Deeds said at a press conference on Thursday reported Reuters.

Granbury is located in Hood County and Bell said that seven were still missing and 45 people were injured.

A tornado may have hit severel times in Hood, Dallas, Parker and Tarrant Counties.  "With these types of tornadoes, they touch down, they lift up, they touch down. They tend to hopscotch," Matt Zavadsky, a spokesman for MedStar Mobile Healthcare said to CNN. "The darkness doesn't help, but the crews on scene are doing a really good job to try and reach out to the folks who might be trapped or unable to get to a shelter or the triage area."

Hood County Judge Darrell Cockerham told CNN that there were reports of homes in Granbury being flattened while people were inside and in Ellis County a tornado shut down power for many people in the city said city manager Steve Howerton to CNN.

"Several buildings in the downtown historic district have been seriously damaged," he said to CNN.

Many people suffered injuries from the tornadoes.

"There are a lot of traumatic injuries," she Donna Martin who is a worker at a local veterans association. "My husband told me that a car was lifted in the air. It just came in and hit so fast."
