Flash flooding forces evacuations and emergency declarations in Southwest
Heavy Pacific storm systems brought intense rain to parts of the U.S. Southwest, triggering flash floods that led to evacuation orders, swift-water rescues, emergency declarations, and widespread road and highway closures in states including Arizona, Colorado, New Mexico, and Utah.
Heavy Pacific storm systems brought intense rain to parts of the U.S. Southwest, triggering flash floods that led to evacuation orders, swift-water rescues, emergency declarations, and widespread road and highway closures in states including Arizona, Colorado, New Mexico, and Utah.
What This is
- A series of Pacific storm systems dumped heavy rain across the Southwest and triggered flash flooding in multiple states.
- Flood watches covered nearly all of Arizona and parts of Utah, Colorado, New Mexico, and Nevada, with some areas facing around 4 inches of rain on saturated ground.
- Mandatory evacuations were ordered in places including Sedona, Arizona, and parts of Archuleta County and Pagosa Springs, Colorado.
- Emergency crews carried out water rescues as floods swept over roads, trapped drivers, and damaged bridges and other infrastructure.
- Forecasters warned the San Juan River could crest at or above historic levels near Pagosa Springs, raising fears of catastrophic flooding.
- In parts of the Four Corners and the Navajo Nation, flooding damaged water and wastewater systems and raised health concerns from contaminated water and mud.
Why This Matters
- Flash floods can become life-threatening within minutes, especially on roads, in canyons, and in normally dry washes.
- Damage to bridges, highways, and utilities can cut off towns and strain emergency budgets.
- Contaminated floodwater and sewage leaks can create immediate health risks and slow recovery.
