Nueces River near Asherton: warning, stage and forecast
A Severe Flood Warning remained in effect for Dimmit County covering the Nueces River near Asherton with the alert listed through 26 July 2026 at 00:06. Major flooding was occurring and forecast to continue, with authorities noting the river was approaching the flood of record and expected to crest at 31.4 feet early the following afternoon before falling below flood stage early Saturday afternoon. Areas adjacent to the river were expected to experience significant water rise that could impact roads and low-lying properties, and the advisory emphasized that the warning indicated flooding was already happening or imminent.
San Antonio River at Hwy 72 near Runge: measured stage and crest timing
A Severe Flood Warning also covered Goliad and Karnes counties for the San Antonio River at Hwy 72 near Runge with the alert active until July 20, 2026 at 19:45. As of 2:15 AM CDT on July 19 the river stage measured 34.8 feet, above the flood stage of 27.0 feet, and forecast to rise to a crest of 35.2 feet later that morning before falling below flood stage the following morning. The measured stage and forecast crest signaled overtopping of banks and potential inundation of nearby low-lying areas and crossings.
Safety guidance, emergency contacts and local impact
The advisories reiterated standard safety guidance: in case of emergency dial 911 follow local authorities, and avoid flooded roads. Officials warned that most flood fatalities occurred in vehicles and reminded the public that as little as 6 inches of fast-moving water can knock a person off their feet and 2 feet can float a car. Motorists were urged to “turn around and do not drown” when encountering floodwaters and to seek alternative higher-ground routes rather than attempting to cross submerged bridges or low water crossings. Caution was also advised when walking near riverbanks.
Current status and monitoring
Both warnings indicated active monitoring of river stages and forecasts, with expected crests and timing provided for local planning and response. Residents in the affected counties were advised to remain alert to updated forecasts and to heed guidance from emergency managers as water levels change. The situation remained evolving with crests expected in the near term and falling below flood stage predicted after the crest periods described in the advisories.
