A severe thunderstorm is moving into San Antonio from the west with the potential to bring quarter-sized hail, according to the National Weather Service.

At 9:44 a.m., the NWS issued a warning for the storm over Joint Base San Antonio-Lackland and moving northwest at 30 miles per hour. The storm could bring large hail, wind gusts up to 60 miles per hour, and flash flooding.

Heavy rains Tuesday night and early Wednesday warning brought flooding and power outages to parts of San Antonio, according to CPS Energy. At the peak of outages around 2:30 a.m., 30,962 people were without power, according to the utility.

CPS Energy had restored service to all but 5,733 customers as of about 9:15 a.m., according to a news release.

Multiple roads around the city were remain closed because of flash flooding, according to BexarFlood.org, Bexar County’s flood information webpage.

The San Antonio Fire Department responded to nine water rescue calls before 5:30 a.m., according to a news release from the department.

“[SAFD] can’t stress the ‘Turn Around, Don’t Drown’ message enough. Even in relatively shallow water, tires can act as flotation devices lifting up even large vehicles and sending them downstream,” the release states. “Driving through flooded roadways not only puts your life at risk and anyone in your vehicle, but also the lives of our first responders.”

There are also penalties associated with driving around road barricades when water is on the road: a maximum $2,000 fine and 180 days in jail.

Everyone in the vehicle could be charged $640 in the event of a water rescue, according to SAFD.
