As many as three tornadoes swept through a stretch of Texas near the Dallas-Fort Worth area, causing major damage to homes, reported Reuters.

According to Hood County Sheriff Roger Deeds, a deadly tornado struck two neighborhoods of Ranchos Brazos Estates and DeCordova Ranch in Granbury city at around 8 pm on Wednesday. The death toll is expected to rise and those injured were reportedly in serious condition.

Deeds said the twisters caused damage to places located three miles east of Granbury. He added that more than 90 people were evacuated from those areas. Officials are still trying to put a number on the evacuees, reported
