Heavy rain on Sunday, November 8, caused flooding in San Antonio and prompted 10 road closures across the city, according to the Bexar Flood map. Storms also left four active CPS Energy outages affecting seven customers as of 8 a.m. Sunday.
Why it matters
Water over roads closes them to traffic, and driving around barricades at low water crossings is illegal, so drivers face disruptions during the storm. Rain continues into early next week, and residents should expect ongoing risk as conditions develop across San Antonio.
The Bexar Flood map reports 10 road closures across San Antonio, while CPS Energy recorded four active outages affecting seven customers as of 8 a.m. Sunday. Power outage figures are expected to increase through the day, and the final count of affected customers had not been confirmed.
The players
CPS Energy
CPS Energy is the municipally owned utility serving San Antonio, which reports power outages and restoration work to customers.
Bexar Flood
Bexar Flood is the flood information map maintained for Bexar County that tracks road closures and flooding conditions in the region.
The details
Rain fell heavily on Sunday morning, flooding parts of San Antonio and prompting road closures. San Antonio and much of the Texas Hill Country are under a Level 1 risk for excessive rainfall, with the risk rising to Level 2 further south.
Timeline
Sunday, November 8, morning: Flooding and 10 road closures occurred across San Antonio.
As of 8 a.m. Sunday, November 8: CPS Energy reported four active outages affecting seven customers.
Sunday into early next week: Rain continues to fall across San Antonio.
Seasonal Patterns
The Level 1 and Level 2 excessive rainfall risk categories used in this forecast follow the National Weather Service outlook scale, which rates the likelihood of flooding-producing rain across Texas. The escalation from Level 1 near San Antonio to Level 2 further south reflects how that outlook scale signals rising flood potential over successive days.
Drivers should avoid roads covered by water and never drive around barricades at low water crossings, which is illegal. Residents should monitor CPS Energy outage reports and be prepared for further road closures as rain continues into next week.
The takeaway
Flooding can close roads quickly, so checking conditions before traveling and heeding barricades keeps drivers and emergency crews safe during heavy rain.
What happens next
Rain is forecast to continue into early next week, and power outage figures are expected to increase as the day goes on.
