Mandatory evacuations are underway in parts of Arizona and Colorado due to flash flooding caused by heavy rainfall across the Southwest. Officials in Pagosa Springs, Colorado, have warned of potentially catastrophic flooding as the San Juan River is forecast to crest at over 19 feet, surpassing the mark set during a devastating flood in 1911. The Archuleta County Sheriff’s Office noted that the expected crest is higher than the 17.8 feet recorded during the 1911 event, predicting extensive damage.

In Arizona, the tourist town of Sedona has seen rapid rises in Oak Creek, prompting immediate evacuation orders for residents in nearby areas, with multiple individuals reported trapped in their homes. Camp Verde has also issued an evacuation order for areas adjacent to the Verde River, West Clear Creek, and Wet Beaver Creek.

Aaron Hardin, a meteorologist with the National Weather Service in Tucson, stated that the region is experiencing two to three months' worth of rain within a few days. This has led to flash flooding and possible river flooding in Tucson, some 230 miles south of Sedona, necessitating swift water rescues.

The current round of heavy rain began Saturday evening and is expected to continue through Monday, bringing the threat of flash flooding to already saturated ground. The weather service anticipates up to 4 inches of rain across the region, fueled by a series of Pacific storm systems. Flood watches have been issued for nearly all of Arizona, as well as parts of southern Utah, southwestern Colorado, and western New Mexico, including the Four Corners region.

Pagosa Springs officials have directed residents in low-lying areas along several rivers to proceed to a designated shelter. They have urged immediate departure, warning that emergency crews may have limited capacity during the storm's peak. The highway into the town is also scheduled to close to inbound traffic.

In Sedona, residents affected by the flooding were advised to go to Sedona Red Rock High School. Authorities emphasized the danger of attempting to drive through flooded roads and warned people to stay clear of creek beds and washes. Sedona Fire District Chief Ed Mezulis reported that emergency crews from surrounding communities were en route to assist local responders who were already addressing multiple calls of residents trapped by rising waters. He advised residents to seek high ground, monitor alerts, and exercise caution. Videos shared by the fire department depicted floodwaters submerging vehicles and rushing past homes and structures.
