It was a cold night for thousands of area residents who depend on electricity to keep warm.
At one point, more than 20,000 homes and business were without power, and CPS Energy spokeswoman Yvonne Casanova says most of the problems were attributed to downed power lines as freezing rain and high winds moved across the area.
"We want to remind everyone to stay away from downed power lines. They should be treated as though they're live and dangerous," said Casanova..
She told 550 KTSA News one of the biggest outages occured in the Northwest Side along Loop 1604 from Bandera Road to Culebra Road.
Casanova says crews are working 'round the clock to restore power and she's asking that CPS Energy customers be patient.
"Our crews have to do this work under some pretty bad conditions and we want to make sure that they do their job safely," she said.
