Tornadoes Touch Down In Dallas Vicinity

A severe storm system moved across northern Texas late Sunday and early Monday, bringing with it hail, high winds and multiple reports of tornadoes.

The Fort Worth office of the National Weather Service said Sunday night it had received reports of twisters in locations across Johnson and Hill counties.

A tractor-trailer was blown over, CBS Dallas tweeted.

One funnel was seen touching down near Blum, the station said. Another was confirmed just west of Rio Vista, and another near Grandview.

Tornado warnings and watches were in effect for a time for a large swath of north-central Texas, including Dallas and Fort Worth.

TV footage from Rio Vista in Johnson County, where a tornado was reported, showed downed trees and debris from structures.

The Johnson County Sheriff's Office said just after midnight that the extent of damage wasn't immediately clear. Deputies were headed to affected areas. There were no immediate reports of injuries.

Hill County Emergency Management had no immediate reports of injuries or major damage.

Some 11,000 homes and businesses were left without power.

Storm chasers broadcast images earlier Sunday of a tornado in the area of rural Comanche and Erath counties.

Baseball-size hail was reported near Stephenville, about 70 miles southwest of Fort Worth.

Flash flooding was a concern due to torrential downpours from the severe thunderstorms. Police in Maypearl said some residents were being evacuated to the local high school due to rapidly rising floodwaters.
