RUNAWAY BAY, Texas (AP) — A tornado-producing thunderstorm left at least two people dead in northern Texas and displaced at least 20 families, with many homes sustaining major damage, authorities said Sunday.

At least one person was killed and numerous homes were damaged Saturday night in the town of Runaway Bay, said Wise County Judge J.D. Clark, who serves as the county’s chief executive. Emergency responders worked to clear debris to reach damaged homes and provide medical care where needed, Clark said.

“Access has been difficult due to blocked roadways and downed utilities, but crews have continued pushing forward to reach those in need,” Clark said.

The storm also hit Springtown, where Parker County Assistant Fire Chief David Pruitt said in an email that a second person died south of the city limits. There was “significant damage” in the area, Pruitt said.

National Weather Service teams confirmed that an EF-2 tornado with peak winds of 135 mph touched down in the Runaway Bay area. An EF-1 tornado with peak winds of 105 mph was confirmed in the Springtown area, the weather service said.

The slow-moving supercell traveled through the area around 10 p.m. Saturday, said meteorologist Patricia Sanchez with the Fort Worth weather service office.
