Josefina Guajardo stood on her porch in Chula Vista, Texas, and watched the Nueces River swallow her town. It had been 8 feet deep the night before. By Friday morning, July 18, it was 30 feet and still climbing. Half the homes in her community would soon be marked unlivable.
The Texas floods 2026 are not a single storm. They are a sequence: days of unrelenting rain, rivers that forgot their banks, and then a tropical storm. As of July 25, three people are dead, 59 counties are under a disaster declaration, and the Nueces River is still pushing floodwater toward communities that have not seen the worst yet.
What Happened: Two Weeks of Water
The crisis began on July 13, when a stalled weather pattern parked itself over Texas and began dumping rain. In the Hill Country west of San Antonio and Austin, the rocky limestone hills funneled runoff directly into the Guadalupe, Frio, and Nueces Rivers. By July 14, Governor Greg Abbott had declared a disaster for 59 counties and directed the Texas Division of Emergency Management to begin rescue operations.
The Nueces River near Uvalde set a new record height, destroying part of a bridge that connects Uvalde to Eagle Pass. In Kerrville, floodwater from the Guadalupe River surged through downtown, overwhelming the sewer system and forcing the city to issue a public health notice about sanitary sewer overflow near Town Creek. Firefighters in Boerne navigated floodwater in rescue boats on July 15, pulling families from rooftops and cars as streets turned to rivers.
By July 17, two people were confirmed dead. The USA Today report described the scene in the Hill Country as “catastrophic,” noting that the flooding arrived almost exactly one year after the July 2025 Texas floods that killed more than 130 people, including 28 at a Christian summer camp called Camp Mystic. For families who had just finished rebuilding, the sound of rising water was a nightmare they had already lived.
Then, on July 22, Tropical Storm Bertha made landfall in St. Bernard Parish, Louisiana, with sustained winds of 45 mph. It was the second named storm of the 2026 Atlantic hurricane season. Bertha crawled along the Gulf Coast and made a second landfall near the Texas-Louisiana border on July 23, near Lake Charles, dragging a tail of heavy rain across already-saturated ground. Governor Abbott confirmed a third fatality on July 24, warning that communities downstream along the Nueces River would face rising water into early August.
By the Numbers: The Scale of the Disaster
The Nueces River reached major flood stage at 29 feet (8.8 meters) in Cotulla, according to the National Weather Service monitoring station. It has since crested in some areas but continues to threaten communities near the Lake Corpus Christi reservoir, where water levels are expected to keep rising for days.
In Chula Vista, a small community in South Texas, the Texas Tribune reported that the flood damaged 183 properties. Nearly half were declared unlivable by their owners. The river had jumped from 8 feet to 30 feet overnight, leaving residents with minutes to escape and no time to save their belongings.
Governor Abbott requested federal disaster assistance for 33 of the 59 counties under the state declaration. The Federal Emergency Management Agency has begun damage assessments, though the full cost will not be known for weeks. The floodwater carried sewage, fuel, and debris through residential neighborhoods, creating a public health risk that will outlast the receding water.
The Human Impact: What a Flood Takes
Floods are not measured in feet of water. They are measured in what the water takes.
Homes. In Chula Vista, nearly 90 families learned within 24 hours that their houses were no longer safe to enter. Across the 59-county disaster zone, the number of damaged structures runs into the hundreds, and assessments are ongoing.
Health. The Kerrville sewer overflow sent untreated wastewater into a downtown watershed. Floodwater laced with agricultural runoff, gasoline, and debris poses a contamination risk that the Texas Department of State Health Services is monitoring as the water recedes.
Infrastructure. The destroyed bridge near Uvalde severed a connection between two communities. Rural roads across the Hill Country remain impassable. The Nueces River is still moving downstream, and the Lake Corpus Christi reservoir is expected to crest in early August, testing dams and levees built decades ago.
Memory. The psychological burden is especially acute because this is the second catastrophic flood in the Texas Hill Country in 12 months. The July 2025 floods that killed 130 people reshaped the region’s relationship with its rivers. To face rising water again so soon is not just a physical disaster. It is an emotional one.
Why It Happened: The Science Behind the Texas Floods 2026
The immediate cause is straightforward. A stalled upper-level low-pressure system over the southern Plains drew moisture from the Gulf of Mexico and held it in place for days. The resulting rainfall measured in feet, not inches, across the Hill Country. The thin, rocky soil of the Edwards Plateau cannot absorb that much water. It acts like a parking lot: nearly every drop runs directly into the nearest creek, which feeds the nearest river, which rises fast and without warning.
This is what meteorologists call a training thunderstorm pattern: one storm cell follows another over the same ground like train cars on a track. Each cell dumps more rain on soil that is already saturated. Rivers that normally rise over hours instead rise over minutes. This is also the mechanism behind how flash floods work, the fastest-moving and deadliest form of flooding in the United States.
Then came Tropical Storm Bertha. A tropical cyclone does not need to be a hurricane to be dangerous. Bertha’s 45 mph winds were modest, but its moisture content was immense. According to AccuWeather, the storm delivered heavy rain from Florida to Texas over a three-day period. When that rain fell on watersheds already at capacity, it did not add water. It multiplied it.
The broader climate context matters. A warmer atmosphere holds more water vapor. The Clausius-Clapeyron equation, a fundamental law of atmospheric physics, tells us that for every 1 degree Celsius of warming, the air can hold about 7% more moisture. The Gulf of Mexico has been running above its long-term average temperature. Warmer Gulf water means more evaporation, which means more moisture available for any storm that happens to form. The National Oceanic and Atmospheric Administration has documented this amplification effect across multiple flood events in the southern United States.
What Comes Next: Recovery and the River
The rain has stopped in most of the disaster zone, but the Nueces River is not done. Water that fell in Uvalde County on July 15 is still working its way downstream toward the Gulf of Mexico. The Lake Corpus Christi reservoir is expected to rise into early August. Communities along the lower Nueces, including Three Rivers and George West, are watching gauges and waiting.
Federal damage assessments are underway. The Texas Division of Emergency Management has opened recovery centers in the hardest-hit counties. Volunteers from across the state are arriving with cleaning supplies and construction tools.
For Texans living along the Nueces, the Guadalupe, and the Frio, the question is not whether another flood will come. As the Texas floods 2026 recede from memory, the same communities that rebuilt after July 2025 are doing it again. The hurricane preparedness lessons that coastal communities learn apply here too: know your evacuation route. Have a go-bag packed. And never, ever drive through water on a road.
