SAN ANTONIO — Strong winds behind a cold front caused widespread power outages across San Antonio overnight, leaving tens of thousands of customers in the dark at the peak of the storm.

According to CPS Energy, nearly 200 outages were reported overnight, impacting close to 40,000 customers across the city.

Crews have been making steady progress restoring electricity. As of 4 a.m. Monday, CPS reported about 90 active outages affecting more than 10,500 customers.

Outage maps show some of the largest outage areas on the city’s west side near Loop 1604, including neighborhoods like San Antonio Creekside, Rolling Oaks Estates and Big Country.

Another area seeing clusters of outages is on the southwest side near Palo Alto College.

Officials say strong winds can knock down power lines and make repairs more difficult. When wind speeds exceed about 25 mph, CPS crews may have to stop using bucket trucks and climb poles instead, which can slow restoration efforts.

CPS Energy is urging residents to stay away from downed power lines and treat them as if they are energized. People should also avoid driving over fallen lines and secure loose outdoor items that could be blown into power equipment.

Crews continue working to restore service as conditions allow.
