New Flood Warning Systems Put to Test in Texas Hill Country as Storms Return

When catastrophic flooding swept through the Texas Hill Country last July, killing more than 136 people including 28 at a girls’ summer camp, state officials promised sweeping reforms. Those commitments included deploying improved early warning infrastructure, establishing stricter safety protocols for youth facilities and upgrading the region’s water management systems.

The commitment faced its first major test this week as severe storms pounded the same vulnerable region. Flash flooding struck multiple communities with at least two deaths reported and hundreds requiring emergency rescues.

However, residents across several devastated zones credited the new warning apparatus with making a tangible difference. Sirens newly installed throughout the area began wailing in the pre-dawn darkness, urging evacuation. Residents’ phones lit up with alert notifications that never materialized during the previous year’s catastrophe.

Despite these improvements, residents in several communities reported being caught off-guard by suddenly rising water levels. The obstacles to comprehensive warning coverage underscore the difficulty of protecting a broad, sparsely populated region frequently vulnerable to sudden flooding events.

Local authorities demonstrated noticeably greater willingness to issue emergency warnings this time around. Kerr County officials sent four evacuation alerts Thursday, while the city of Kerrville issued one, contrasting sharply with last year’s hesitation to order residents away from danger zones.

Suzanne Sutphin Gschwind, a Kerrville resident, highlighted the stark contrast between the two events. “Last year, we got no alarms. We had no idea what was going on,” she said, noting this week’s experience brought repeated messages from city officials, weather services and her home security system occurring roughly every two hours.

The National Weather Service issued 38 separate alerts across southwest Texas communities between Tuesday morning and Thursday at 9 a.m., comprising 14 tornado warnings and 24 flood-related notifications.

Coverage gaps persisted despite expanded efforts. Uvalde County, which experienced severe flooding damage, appeared to have no wireless emergency alerts sent by local agencies according to Associated Press records review, though officials may have utilized alternative notification methods.

Jaclyn Gonzales learned of danger only when a friend phoned at 2 a.m. Wednesday to report a potential tornado threat. She discovered water already covering her floor upon waking.

Kat Sprawls received her only warning through a friend’s phone call at 3:30 a.m. Friday near Batesville. Because her device was silenced, multiple attempts were needed before she heard the alert—by then water was already threatening her home.

Zavala County law enforcement has since shifted to direct outreach, with deputies conducting door-to-door notifications while posting evacuation information on social media platforms.

Newly operational sirens in Ingram and across Kerr and Kendall counties activated this week to alert residents, according to state Sen. Paul Bettencourt, who championed legislation providing funding for such infrastructure. Twenty-eight additional counties qualify for similar flood-warning equipment investment and are developing implementation strategies for state approval.

Tara Bushnoe, manager of the Upper Guadalupe River Authority, reported that three of six newly installed sirens in Kerr County were activated to direct residents to elevated terrain. The remaining three sirens were positioned in areas experiencing only minor water rise.

Comfort, a small Hill Country municipality, recently expanded its siren network from one to three devices. Assistant Fire Chief Danny Morales acknowledged the persistent challenge of convincing reluctant residents to evacuate, requiring multiple alarm activations to drive home the urgency.

Private enterprise has emerged to supplement government efforts. River Sentry, founded following last year’s disaster by Ian Cunningham, manufactures flood-alert sirens for private facilities including campgrounds and hospitality venues. The company has installed 104 such devices along the Guadalupe River corridor, several positioned near an RV park where dozens perished in 2025.

Cunningham noted the unexpected early deployment of the newly installed sirens: “We installed them about three months ago and did not expect them to be used so soon.”

Technology companies are also expanding capabilities. Hononu received a state contract facilitating agencies’ adoption of its water-sensor and real-time alert network. Watch Duty, a widely-used wildfire monitoring application, added flood-tracking functionality earlier in 2026.

Gov. Greg Abbott credited the expanded preparedness with improving outcomes during the latest emergency. “Everybody in Texas has been far more prepared to deal with what has happened this year,” Abbott stated during a Uvalde news conference. “Lives have been saved.”
