As of 12:15 a.m. Sunday, Aug. 30, 2026, exactly 47,276 CPS Energy customers remained without power across the San Antonio area following severe storms that struck Friday night, down from a peak of 112,000 outages, according to utility officials.
CPS Energy Warning on Multi-Day Outages
CPS Energy Interim President and CEO Frank Almaraz warned that some customers could remain without electricity for several days following the storms, which generated 653 active outages and about 250 downed-wire calls. “We have down lines, broken poles and fallen trees. Some of these outages are going to extend several days,” Almaraz said, urging residents to put emergency plans into effect and make arrangements to stay cool. The prolonged power failures coincide with persisting hot weather through the weekend, as overnight lows fall only into the upper 70s before Sunday temperatures climb to around 98 degrees with heat index values reaching 101, according to utility and weather reports.
National Weather Service Wind Damage and Radar Data
The National Weather Service reported that widespread tree damage occurred in a corridor stretching from northeast Bexar County through central San Antonio into southwest Bexar County. Emergency managers recorded scattered damage to fences, power lines, power poles, and roofs, while West Side traffic lights were ripped from their supports. According to the Weather Service, the destruction was consistent with straight-line winds, measuring speeds of 50 to 65 mph with radar-estimated pockets of 75 mph. A peak gust of 77 mph was officially recorded at San Antonio International Airport.
City Relief Efforts, Cooling Centers, and Transit
Mayor Gina Ortiz Jones announced that libraries and park centers were operating as cooling centers during normal Saturday hours, allowing pets. However, several library branches—including Bazan, Las Palmas, and San Pedro—remained closed due to power outages. The city also opened six resilience hubs offering emergency resources such as power, device charging, and Wi-Fi, which will remain open overnight through 4 p.m. Sunday. VIA Metropolitan Transit is providing free transportation to cooling centers and overnight resilience hubs, while residents needing medical equipment assistance or nonemergency help can contact 311 or 210-207-6000.
Resident Impact and Recovery Operations
Residents across San Antonio recounted harrowing experiences from the storm and its aftermath, ranging from theater power failures during a sold-out performance of “Aye, No!” to spoiled groceries and debris removal. City crews are actively clearing downed trees and public rights-of-way, and the Brush Collection Center at 1800 Wurzbach Parkway will open Sunday from 8 a.m. to 5 p.m. with storm-related disposal fees waived. Officials encourage residents to report property damage through the state’s iSTAT damage survey and remind the public to treat downed power lines as live, operate generators outdoors, and keep refrigerator doors closed.
