The Dallas-Fort Worth area saw a string of severe storms Tuesday afternoon, with major tornados reported throughout the metroplex according to the National Weather Service (NWS).

"It appears we've had at least two, possibly three significant tornados," NWS meteorologist Steve Fano told CultureMap. "Right now we're getting multiple damage reports for Arlington, Lancaster and areas east of Dallas."

The Severe Weather Blog for WFAA-TV reported extensive damage as storms move northeast through the region. Tornados already have torn off the roofs of numerous homes, tossed heavy trucks into the sky (see the video above) and caused damage to several schools. As of yet, no major injuries have been reported.

Golf ball-sized hail was reported just north of the Dallas-Fort Worth International Airport, where flights were delayed up to three hours. Serious damage was also spotted at Six Flags over Texas in Arlington, where the mayor declared a state of disaster.

"We'll have a better idea of the types and strengths of the tornados tomorrow," Fano said. "We generally assess the structural damage to larger buildings along the path of the storms. There should be a full damage survey by Wednesday afternoon."
