San Antonio

Severe thunderstorms inundated the Interstate 35 corridor in Texas early Wednesday morning, leading to significant flash flooding across various areas of San Antonio. The intense weather resulted in at least eight water rescues facilitated by the San Antonio Fire Department, although fortunately, there were no reported injuries.

The intersection of U.S. Highway 281 and Brook Hollow Boulevard emerged as the epicenter of flooding, where traffic cameras displayed numerous vehicles struggling to navigate through dangerously swollen waters. Flash flooding also caused multiple road closures in Bexar County, particularly affecting regions prone to low-water crossings. Local rain gauges measured rainfall totals of between 2 and 3 inches within just one hour.

This latest flash flooding was the second instance of severe flooding in San Antonio that week, following heavy rains that occurred on Monday night. The National Weather Service has continued to monitor the threat, having issued and extended a flash flood warning for much of Bexar County as additional storms were predicted.

Current Weather Conditions

As severe thunderstorms continued to sweep through the area on Wednesday, the Houston area was also expected to face similar weather challenges later in the day. The National Weather Service has indicated that an additional rainfall of 1-3 inches is possible, which may further enhance flooding risks. Residents are advised to remain vigilant and exercise caution, particularly if they must travel over flooded roads.

During the morning rush hour, the rainfall unleashed chaotic scenes throughout the area, as drivers encountered hazardous travel conditions. The current weather pattern is expected to persist across Texas throughout the week, with isolated severe thunderstorms, potential hail, and a Level 1 out of 5 risk for severe storms indicated for the San Antonio region.

Future Forecast

Looking ahead, meteorologists anticipate additional storms in the late afternoon and evening, though the overall coverage of these weather events is expected to remain low. In conjunction with these storms, a weak cold front is projected to advance through South Texas, which may result in slightly cooler temperatures while keeping warm conditions prevalent.

Motorists and residents are specifically advised to exercise heightened caution during nighttime travel due to the decreased visibility of floodwaters. Ongoing monitoring of local weather reports and adherence to safety advisories is recommended as San Antonio faces continued storm activity and potential flooding hazards.
