A severe thunderstorm warning covered southwestern Bexar, southern Medina and northwestern Atascosa counties Friday evening, and a separate flash flood warning took effect for northern Bexar and south-central Comal counties at 9:35 p.m., after 2 to 3 inches of rain had already fallen with another 1 to 2 inches expected. The storms downed trees and power lines across the area. On the North Side, a large tree fell onto an apartment building in the 11200 block of Perrin Beitel near Wurzbach Parkway, forcing residents to evacuate and knocking down power lines at the scene. No injuries or deaths had been reported when this article was first published Saturday. Later that weekend, San Antonio police said they were investigating two possible storm-related drowning deaths: a 46-year-old woman was found dead Saturday night, and Mayor Gina Ortiz Jones said she drowned as a result of the severe weather. The Bexar County Medical Examiner’s Office ruled her drowning an accident, KSAT reported.
CPS Energy reported roughly 562 active outage events and about 250 downed power lines still being addressed as of Saturday morning. San Antonio Mayor Gina Ortiz Jones said restoration efforts would continue into the weekend, with debris clearance underway, and CPS Energy interim CEO Frank Almaraz said crews would “continue to work 24/7 until we’re done.” Neither official gave a specific date or time for when power would be fully restored.
Update, Monday, Sept. 1: power fully restored
CPS Energy said power has been fully restored to all customers affected by the Aug. 28 storms. The multi-day restoration effort, which at points involved more than 80 crews assisted by contractors and Pedernales Electric Cooperative, required replacing more than 60 utility poles and 137 transformers and clearing debris from hundreds of fallen trees.
Update, Sunday, Aug. 30
Outages stretched into a third day: roughly 60,000 CPS Energy customers were still without power as of Saturday evening, according to Texas Public Radio. The city opened public libraries as daytime cooling centers and several Parks and Recreation community centers as overnight resilience hubs, with free VIA Metropolitan Transit rides offered to reach them, KSAT reported. City officials said residents not already on the vulnerable-population list who need help should call 311.
