Heavy rain is expected to continue across South Central Texas Wednesday, with forecasters warning that the threat of flash flooding remains high through Thursday.
Why it matters: Saturated ground means even modest additional rainfall could quickly trigger flash flooding, especially around low-water crossings and flood-prone roads.
State of play: A flood watch is in effect in San Antonio until 7pm Thursday. Areas west and northwest of San Antonio — including parts of Uvalde, Kerrville, Fredericksburg and Edwards — are under flash flood warnings as of 6am Wednesday.
- Additional storms could redevelop later Wednesday and again Wednesday night into Thursday morning.
By the numbers: NWS forecasts widespread rainfall totals of 2 to 6 inches through Thursday across much of South Central Texas, including the Interstate 35 corridor.
- Areas west of San Antonio, including the Rio Grande Plains and Southern Edwards Plateau, were estimated to receive another 6-12 inches, with isolated pockets of 15-20 inches into Wednesday.
Zoom in: Forecasters are also monitoring the Pecos, Rio Grande, Nueces and San Antonio rivers for minor to moderate river flooding as runoff from repeated rainfall flows downstream.
Between the lines: At least 10 roads were closed throughout Bexar County Wednesday morning due to low water crossings.
- Most trails at Guadalupe River State Park are closed as rain continues, while conditions remain unsafe and officials monitor the river corridor. Garner State Park suspended day access for Wednesday.
- Rockin' R River Rides, which has locations on the Guadalupe and Comal rivers, closed Tuesday due to the weather.
What's next: The heaviest rain is expected to shift farther west on Thursday before drier weather returns heading into the weekend, though rivers could continue rising even after the rain ends.
