San Antonio experienced severe thunderstorms resulting in flash flooding that led emergency services to conduct multiple water rescues. The storms caused significant travel disruptions and prompted the National Weather Service to issue flash flood warnings.

Additionally, further rainfall is forecasted in the region, raising concerns about ongoing flooding and emergency response efforts.
San Antonio Faces Severe Thunderstorms and Flash Flooding
San Antonio experienced severe thunderstorms on Wednesday morning, causing flash flooding that prompted emergency services to perform at least eight water rescues. Fortunately, there were no reported injuries related to the flooding incident, which primarily affected the region’s infrastructure.
Flash Flooding and Rescues
The most intense flooding occurred at the intersection of U.S. Highway 281 and Brook Hollow Boulevard, where traffic cameras captured several vehicles struggling to navigate through deep water. As the storm unleashed heavy rain, the San Antonio Fire Department responded to multiple distress calls throughout the morning, assisting stranded motorists during the ongoing crisis.
Reports indicated that by 7:30 a.m., many vehicles became stranded in high water, particularly on Interstate 35. The flooding caused significant travel disruptions, particularly during the morning commute when portions of I-35 near San Antonio International Airport were closed in both directions due to hazardous conditions.
Heavy Rainfall Totals
Local rain gauges documented rainfall totals of between 2 to 3 inches in just one hour, contributing to the swift onset of flooding. In the last 48 hours, the San Antonio area reported rainfall totals reaching up to eight inches, exacerbating the flooding issues and increasing the urgency for emergency responses.
Road Closures and Warnings
Due to the severe weather, multiple road closures were implemented across Bexar County. County officials noted that low-water crossings were particularly concerning, prompting warnings for drivers to remain vigilant. The National Weather Service issued a Flash Flood Warning for the area that remained in effect until 10 a.m. CT on Wednesday.
Significant rainfall earlier in the week during storms on Monday night had already strained the region’s drainage systems, leading to similar flooding scenarios. Furthermore, there are additional forecasts predicting more heavy rain across a broad swath of Texas on Wednesday, which could lead to further complications.
Wider Impact of Storms
The storms not only impacted San Antonio but also reached other areas in Texas. Conroe, approximately 40 miles north of Houston, experienced significant rainfall on Wednesday morning. In conjunction with the heavy downpours, the National Weather Service cautioned about potential wind gusts of up to 40 mph and risks of pea-sized hail from the ongoing storms.
Earlier in the week, severe thunderstorms had already caused power outages in several regions, further complicating the recovery efforts amidst the flash flooding. Bexar County’s reservoirs were also reported to be significantly lower than normal for this time of year, highlighting the variability in the region’s weather patterns.
Emergency Response and Recovery Efforts
This week’s remarkable weather patterns have necessitated quick responses from emergency services, with the San Antonio Fire Department actively engaged in rescuing those trapped by the rising waters. Roads that had been previously closed throughout the day were largely reopened by late morning, though major routes continued to be impacted by the flooding.
The combination of heavy rain, rising waters, and ongoing weather threats creates a challenging environment for residents and emergency services alike. Continued vigilance and preparedness remain essential as forecasts suggest that storms may persist in the area.
