A powerful cold front with winds exceeding 50 mph has left over 18,000 customers in South Central Texas without power, primarily affecting the South and West Side of San Antonio. The large-scale outage highlights the vulnerability of the region's infrastructure to extreme weather events and the need for continued investment in resilience and preparedness.
