More than 40,000 CPS Energy customers lost power Sunday night as high winds from a line of heavy thunderstorms ripped through the San Antonio area.

“We have multiple crews on standby & anxiously waiting to serve you,” CPS Energy tweeted Sunday night. “Please stay safe!”

Damage reports began to trickle in late Sunday, including downed tree limbs and small trees. Severe damage to fences, rooftops and even interior walls was reported in the Wildhorse subdivision, just outside Loop 1604 between Braun and Shaenfield roads.

The CPS Energy outage map showed that more than 200 outages affected 42,413 customers at 9:45 p.m. Sunday. As the night wore on, the number of affected customers dropped below 35,000 but the number of outages topped 300. “We WILL work safely overnight until EVERY ONE of our customers’ power is restored!” CPS Energy tweeted after 10 p.m.

The National Weather Service issued a flash flood warning for most of Bexar County. Previously, the weather service issued a tornado warning at 8 p.m., tweeting at 8:11 p.m.: “We are watching rotation on a tornado warned cell headed towards the Helotes area. If you are in NW Bexar County take shelter NOW.”

The weather service posted additional weather warnings as the storms pressed east.

Forecasters reported straight-line winds of up to 70 mph during the height of the storm.
