Texas streamflow

# Texas Natural Disaster Report – July 22, 2026

Texas faces dual natural disaster threats as of July 22, 2026. Major river flooding is actively occurring in South Texas, with the Frio River at Tilden (Live Oak and McMullen Counties) and Nueces River at Cotulla (La Salle County) experiencing significant flooding. The Frio River is forecast to crest at 29.1 feet tomorrow evening, well above the 22.0-foot flood stage, while the Nueces River is expected to remain elevated through early Monday, affecting communities including Tilden, Three Rivers, Mathis, Bluntzer, and Calallen. Simultaneously, Tropical Storm Bertha is approaching Southeast Texas from the Gulf of Mexico, approximately 380 miles east of Galveston, and is expected to make landfall late Thursday as a weakened tropical storm. Tropical Storm Watches are active for coastal areas including Galveston Island, Bolivar Peninsula, Brazoria County, and the upper Texas Coast near Port Arthur and Sabine Pass. While Bertha is expected to weaken significantly, residents should prepare for localized hazardous winds (39-57 mph potential), storm surge of 1-3 feet in vulnerable coastal areas, and isolated rainfall flooding. Residents in affected river valleys and coastal communities should monitor conditions closely, complete emergency preparations immediately, and follow evacuation orders from local officials if issued.
