CPS Energy crews continued working Saturday to restore power after severe storms knocked out electricity across the San Antonio area Friday night.

CPS Energy Interim President and CEO Frank Almaraz warned that some customers could remain without electricity for several days.
“We have down lines, broken poles and fallen trees. Some of these outages are going to extend several days,” Almaraz said. “So please begin making plans now. Put your emergency plan into effect and make plans to stay cool somewhere.”
The prolonged outages come as temperatures approach triple digits. The National Weather Service forecast a high near 98 degrees Saturday, with the heat index reaching as high as 102. Sunday’s high is also expected to reach 98, with a heat index of up to 101.

In a preliminary storm report Saturday morning, the Weather Service said widespread tree damage occurred in a corridor stretching from northeast Bexar County through central San Antonio into southwest Bexar County. Emergency managers also reported scattered damage to fences, power lines, power poles and some roofs.
On the West Side, traffic lights were ripped from their supports, and residents worked Saturday morning to remove fallen trees from their homes. Damage was also reported north of downtown. San Antonio College canceled Saturday classes following the storm.

The Weather Service said the damage was consistent with straight-line winds. Measured wind speeds reached 50 to 65 mph, with pockets of winds around 75 mph estimated from radar and the resulting damage. A peak gust of 77 mph was recorded at San Antonio International Airport.
CPS Energy urged customers still without power to report outages and stay away from downed power lines.
“So we’re asking our community to call 311 if they need to report there’s debris on the road or their house was damaged, or if they have vulnerable members of our community that may need assistance,” Deputy City Manager María Villagómez said.
People whose medical equipment is affected by an outage should call 911 in an emergency or 311 for nonemergency help. Residents can also submit nonemergency requests through the city’s online 311 portal or the 311SA mobile app.
Mayor Gina Ortiz Jones said libraries and park centers will operate as cooling centers during their normal Saturday hours, and pets are allowed. VIA Metropolitan Transit is also providing free rides to cooling centers for residents who need transportation.
Some library branches remained closed because they were also without power, including Bazan, Las Palmas and San Pedro. The city said it would provide updates as those locations reopen.
The city has also opened several resilience hubs, which provide emergency resources such as access to power, device charging, Wi-Fi and other basic needs. Residents without power who need refrigeration for medication can use a resilience hub or call the CPS Energy Customer Response Unit at 210-353-2783 for assistance.
The Normoyle Senior Center, Gilbert Garza Community Center, Miller’s Pond Community Center and Copernicus Community Center were open Saturday afternoon. The Southside Lions Senior Center and Northeast Senior Center were scheduled to open at 4 p.m.
CPS Energy recommends keeping refrigerator and freezer doors closed as much as possible during an outage. Anyone using a generator should operate it outdoors and away from doors, windows and vents to prevent carbon monoxide poisoning.
Officials urged residents to use caution as crews continued clearing debris and repairing damaged equipment.
