SAN ANTONIO – In San Antonio, it’s not a matter of if flooding will occur every year, it’s a matter of when.

Every year, flash floods happen across the city as heavy storms move through the area, often during hurricane season. Bexar County officials monitor 178 low-water crossings, updating road closures when they occur.

Drivers warned to ‘Turn Around, Don’t Drown’

While more seasoned residents know which places to avoid, newer residents may not know which areas are most prone to flooding:

Salado Creek at I-35:

When heavy rain falls, the water pools up on the access roads, resulting in closures in the area.

Basse Road and 281:

After heavy rains, Olmos Creek will quickly rise, flooding the roadways it runs through.

Pinn Road:

Pinn Road and Highway 151 has been the scene of some notable high-water rescues before. Leon Creek runs below the road, leaving it prone to flooding.

Lower levels of I-35:

The lower levels of I-35 tend to shut down after heavy rains lead to flash floods on the highway.

While those are some of the most well-known flooding spots, intersections around San Antonio can also flood, depending on where the rain falls.
