Fewer than 10,000 Dallas-Fort Worth residents will be without power by 10 p.m. Sunday, and that number will drop to 3,000 by morning, an Oncor spokesman said.
Kris Spears, a spokesman for Oncor Electric Delivery Co., said all storm-related power outages will be fixed by noon Monday.
The extensive damage from the storm Thursday was caused by straight-line winds up to 100 mph, Spears said.
“The storm that came through was definitely deceptive,” Spears said. “It really only rained and the wind only blew for about 15-20 minutes, but we saw an excess of 90-mph winds, and uprooted trees that fell onto our lines and equipment leaving hefty damage done in short time.”
The winds left 302,000 Metroplex customers without power Thursday night.
More than 5,000 Oncor employees and mutual assistance personnel from across Texas and six other states have been working 16-hour shifts to restore power to customers, according to Oncor.
Tarrant and Dallas county electrical facilities had to be rebuilt, and Spears called the outages some of the “most complex” the company has worked on.
The remaining 3,000 customers without power will need electrical repairs and city inspections at their homes and businesses before power can be restored, Spears said.
Oncor hoped to have 95 percent of power restored by Sunday night, Spears said.
The city of Arlington slowly returned to normal as all the major intersections opened back up Sunday, and 1,650 customers remained without power, down from 36,650 Thursday, city spokesman Reginald Lewis said.
“Crews are working hard; personnel are working hard to make sure everyone is safe,” Lewis said.
Monday, showers that could bring hail are expected early, with a 30-40 percent chance starting at around 1 a.m. and lasting until about 7 a.m., said Lamont Bain, a National Weather Service meteorologist in Fort Worth.
“The environment that we are looking at does not suggest we are going to see anything in terms of winds that we saw last Thursday,” Bain said.
The overnight storms could include up to quarter-sized hail, Bain said. He said he expects less than a quarter-inch of rain. The good news is that the storms come with an “incredibly low” chance for tornadoes, he said.
Wind gusts could be 30-45 mph, he said.
