FORECAST

FLOODING CONCERNS REMAIN ALONG RIVERS

South Central Texas conditions are improving following historic rainfall, but major to moderate river flooding persists across the the southern reaches of the Nueces, Frio, and San Antonio basins. Waterways will remain elevated through the weekend as floodwaters move downstream. Residents near rivers, creeks, and flood-prone areas should remain vigilant and avoid flooded and destroyed roads.

Areas that could continue to experience high water include:

  • Asherton and Cotulla – Nueces River
  • Derby, Fowlerton and Choke Canyon – Frio River
  • Falls City and Kenedy – Cibolo Creek and the San Antonio River

AQUIFER AND LAKE LEVELS

Water levels remain on the rise across the region. The Edwards Aquifer continues to recharge, while Medina Lake and Canyon Lake are expected to receive additional inflow from swollen rivers and tributaries over the coming days.
