Original Story
Hays County, including San Marcos, is under a flash flood warning until 1 p.m., according to the National Weather Service (NWS).
The NWS stated that as of 9:46 a.m., 1-2 inches of rain have fallen. NWS expects a rainfall rate of 2-4 inches in 1 hour. Additionally, rainfall amounts of 1-3 inches are possible.
“The outdoor warning sirens sounded just a few moments ago due to a Flash Flood Warning issued for our area by the [NWS],” the city of San Marcos wrote in a 9:53 Facebook update. “Please stay weather aware, avoid low-water crossings and never drive through flooded roads.”
NWS said the impact is possible “life-threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses.”
According to the city of San Marcos, these are the areas residents should avoid during heavy rainfall:
- 700 Block McKie at Willow Springs Creek (IH 35)
- 1400 block Uhland Road at Blanco River 200 block C.M. Allen Parkway at Children’s Park
- 2500 Block William Pettus
- Low Water Crossing and Common Flood-Prone Streets Jackman/Gravel at Purgatory Creek
- River Road at Railroad Trestle
- River Road at Uhland Road
Residents can stay safe by turning around when encountering flooded roads, and knowing where they are relative to streams and creeks.
On Memorial Day in 2015, the Blanco River rose to 20.21 feet, destroying over 2,000 homes and killing 11 people in Hays County.
San Marcos is also under a flood watch until 7 p.m., Saturday.
