However whereas the 2 July storms have been typically comparable in depth and impact, they unfolded in distinctive methods — swift and concentrated final 12 months vs. a number of rounds of heavy rain over days throughout a broad area this week.
And whereas climate officers mentioned they took the identical strategy to issuing warnings, residents and responders on the bottom mentioned they’d extra instruments obtainable to them and the motivation of hysteria borne from final 12 months’s horrific tragedy.

Some 7 to 12 inches of rain fell largely over three hours, propelling an enormous and lethal wave of water downstream. The Nationwide Climate Service issued alerts by the storm, however the worst of the flooding occurred in a single day, at the hours of darkness whereas folks slept. Some alerts might not have been obtained if cell service was missing or telephone alerts have been disabled. Some folks described getting alerts however not feeling nervous as a result of floods typically occur in Flash Flood Alley.
The Guadalupe River rose 29 toes in three hours on the gauge the place the 2 forks of the river meet in Hunt, based on U.S. Geological Survey knowledge. Many alongside the waterway discovered themselves attempting to flee a river that rose sooner than they imagined it may.

“The Guadalupe River final 12 months, all of it got here down without delay,” mentioned Greg Waller, a hydrologist with the Nationwide Climate Service’s West Gulf River Forecast Heart in Fort Price. “This one nearly seems to be like a soccer recreation. There’s the primary quarter, then there’s the second quarter. … It’s unfold out.”

Simply because it occurred final 12 months doesn’t lower the probability of it taking place this 12 months.”
Local weather change is making heavy downpours extra seemingly as a result of hotter air is ready to maintain extra moisture. Swain mentioned scientists have discovered that intense subtropical and tropical downpours in thunderstorms like these could be the quickest rising kind of maximum rainfall.
The development of storms over days created what specialists described as invaluable lead time for emergency managers downstream. Durations of lighter climate between rounds of rain allowed forecasters to watch rivers as they rose earlier than the following wave arrived.
Nick Fang, director of the College of Texas at Arlington’s water analysis middle and an knowledgeable in flood prediction and early warning techniques, mentioned the 2026 storm’s evolution allowed forecasters and emergency responders to acknowledge the menace earlier than it reached among the hardest-hit communities.
“Early flood warning doesn’t begin with the sirens, however begins with the science,” Fang mentioned.
Forecasters briefed native officers on calls beginning Sunday to unfold the phrase about incoming storms, mentioned Jason Runyen, warning coordinator meteorologist with the Nationwide Climate Service workplace for the Austin and San Antonio area. In the course of the storm, he mentioned, they have been issuing warnings with the identical strategy as final 12 months, escalating flash flood warnings to emergencies in some locations, together with alongside the Guadalupe and Pedernales rivers and in Uvalde.
