San Antonio Storms Leave Over 17,000 Without Power

Powerful overnight storms swept through San Antonio early Saturday morning, June 20, knocking out power to more than 17,000 CPS Energy customers across the city and surrounding communities. According to KSAT, CPS Energy reported at least 17,000 customers lost electricity due to the severe thunderstorms that struck during the night. As of 7:53 AM, the utility's outage map showed 370 active outage events affecting 17,126 customers, with more than 12,300 of those located within San Antonio city limits. Nearby communities including Bulverde and Castroville also reported outages.

Flooding Complicates Restoration

The storms brought not just lightning and damaging winds, but also heavy rainfall that triggered flash flood warnings across the area. Low-water crossings were closed throughout the city, and CPS Energy warned that flooded roads could delay restoration work. By 3:15 PM, more than 350 outage events were still affecting at least 10,000 customers, with the heaviest concentration of damage on the city's northwest side.

CPS Energy crews worked through Saturday and expected restoration to continue into Sunday. The utility posted on social media that crews were actively responding to the widespread outages caused by the overnight storms. The combination of scattered wind damage and flood-blocked access roads meant that some neighborhoods would see power return within hours while others faced a longer wait.
