Gov. Greg Abbott visited Perryton in the Texas Panhandle, where officials said more than 1,000 customers were without electricity after a tornado killed three people late Thursday. The Perryton Ochiltree Chamber of Commerce said it would open a cooling center in the town of 8,000 people, about 115 miles northeast of Amarillo, to counteract the effects of the high temperatures that followed the storm.
“At times of events like these, Texans come together,” Abbott told reporters as he signed a disaster declaration that he said would “trigger all the resources the state can bring to bear … to accelerate the ability to rebuild.”
Abbott said he was shocked to see how much of the town had been destroyed, and he praised what he called “nonstop heroic efforts by health care providers,” who he said treated 160 injured people at the local hospital, which has just 25 beds.
