Although spring showers have come and gone this year, the risk of flooded roadways has not evaporated. There is no “season” for flash floods, and a flooded roadway can occur with as little as 3 to 4 inches of water in a particular location, according to Jarred Thomas, Williamson County Emergency Management coordinator. Williamson County is experiencing an elevated flood risk because of recent rainfall, Thomas said, and—unlike in dry times— it will not take as much water to flood an area.
Known flood risks and low water crossings
The city of Austin Flood Early Warning System team monitors weather and road conditions and maintains a listing of roadways susceptible to flooding. This map depicts low water crossings but is not comprehensive.
