There were two reports of injuries and “multiple reports of damage to homes and businesses” in Wise County, northwest of the Dallas-Fort Worth area, where one of the tornadoes touched down, the county’s Office of Emergency Management said in a statement. One person was injured by flying debris while traveling in his vehicle and was treated at the scene, the emergency management office said. The other person was taken to the hospital after strong winds overturned an 18-wheeler, although the emergency management office did not release information on the condition of the person being treated. The emergency management office said it was still assessing the damage and that the main areas of concern were south of Decatur, home to 6,500 people, and east of Paradise, a town of fewer than 500 residents. “A confirmed large and extremely dangerous tornado has been located near Decatur,” according to a National Weather Service bulletin issued at 7:20 a.m. Central time. The tornado is no longer a threat to the area, but the line of storms that spawned it could spawn more tornadoes as it moves east. The tornado near the airport was seen on video, according to the Weather Service, crossing a highway near Grapevine, Texas. Passengers were asked to evacuate due to a tornado warning, which was lifted after the storm passed. About 560 flights to and from the airport were delayed, according to FlightAware, a flight tracking website. Outdoor warning sirens also sounded throughout Fort Worth at 8:15 a.m. local time. There were no immediate reports of injuries or damage in Fort Worth. The storms are part of a weather system that brings significant, widespread hazards to the central United States. More than 30,000 customers in Texas were without power Tuesday morning, according to PowerOutage.us, which compiles data from utilities across the country. The risk of severe thunderstorms will move east throughout the day, with more tornadoes possible in the afternoon and evening across eastern Texas, Louisiana and Mississippi. By Wednesday, the threat will move east, likely affecting southern Louisiana and Alabama and putting more populated areas, such as New Orleans, at risk for severe weather.
