San Antonio Grapples with Widespread Power Outages and Flood Warnings as CPS Energy Maps Show 40,000 Affected Customers

San Antonio residents faced a dual crisis as widespread power disruptions coincided with river flooding threats across the region. Nearly 40,000 customers served by CPS Energy lost electricity when severe storms with heavy rain and lightning struck Bexar County, while the National Weather Service simultaneously issued a River Flood Warning for the San Antonio River near Elmendorf. The combination of infrastructure damage and environmental hazards left thousands without essential services during a period when customer support centers remained closed.

Power Outages Across Multiple Neighborhoods

CPS Energy documented 55 distinct outages affecting 39,967 customers throughout the service area. The CPS outage map became the primary resource for residents attempting to track power restoration efforts and identify which neighborhoods remained without electricity. Affected areas included Northwest Crossing near local schools, neighborhoods near Grissom, and sections along Interstate 10 near Huebner Road, indicating the outages were geographically dispersed rather than concentrated in a single zone.

The timing of the outages created additional hardship for residents. CPS Energy's customer service centers remained closed during the period, a closure the company attributed to observance of Juneteenth. Emergency reporting remained available through dedicated phone lines at 210-353-4357 and 1-800-870-1006, with online account management accessible through the company's website and mobile services. However, many customers seeking detailed information about restoration timelines found the company unable to provide updates during regular business hours.

River Flooding Threatens Infrastructure and Farmland

The National Weather Service projected that the San Antonio River near Elmendorf would rise above flood stage late Monday afternoon, with the crest expected just after midnight at approximately 38.4 feet. This level approaches the documented crest of 38.2 feet recorded on April 25, 2015, indicating a significant flood event. The River Flood Warning remained in effect through Wednesday afternoon, affecting portions of Bexar and Wilson counties.

Flood advisories warned of potential impacts to lowland farming operations, pastureland, low-lying roadways, and bridges along the river corridor. Authorities urged residents in flood-prone areas to remain vigilant and avoid crossing flooded roadways, citing the dangers posed by moving water. The combination of electrical infrastructure damage and rising water created compounded risks for affected communities already contending with the loss of power during a weather emergency.
