Heavy rain across the Four Corners region of the U.S. Southwest resulted in water rescues, evacuations, and power outages through Sunday, Oct. 25, 2026. The National Weather Service maintained a flood watch for much of the Four Corners — including parts of Arizona, Colorado, New Mexico, and Utah — as officials monitored swollen rivers and braced for additional thunderstorms.
The current weather pattern follows two months of intermittent heavy rain driven by tropical moisture from the Pacific. This period of precipitation follows months of drought and recent flooding events in the Grand Canyon and parts of New Mexico. Rivers in the region surged as rainfall intensified starting Wednesday, Oct. 21.
In San Juan County, New Mexico, floodwaters reached depths of 4 feet inside the home of Sheriff Shane Ferrari. County spokesperson Devin Neeley reported that while official figures for home damage and total evacuations were not yet available, he was not aware of any loss of life as of Sunday. In Pagosa Springs, Colorado, video footage showed a house almost entirely submerged, with only a portion of the roof and the chimney visible.
Infrastructure damage has hindered recovery efforts. The Colorado Department of Transportation kept the San Juan River Bridge closed Sunday due to significantly increased water flow levels. While waters have started to recede in some areas, they have left behind mud and silt contaminated with sewage following failures at waste plants. Officials in San Juan County said residents in several areas would likely remain without electricity for a few days.
The flooding affects residents across the four-state region, specifically targeting those living near small streams, narrow canyons, and recent burn scars. While official numbers are not yet available, the impact has already left multiple areas without power and forced residents from their homes. In San Juan County, New Mexico, residents are managing property damage from water levels reaching 4 feet, while others in Pagosa Springs, Colorado, have seen structures almost entirely submerged.
Residents in multiple areas will notice a lack of electricity that is expected to persist for several days, and those whose homes were reached by water face mud and silt contaminated by sewage. Transportation is also restricted by the closure of the San Juan River Bridge in southwestern Colorado.
The failure of waste plants has introduced sewage into the flood deposits. The National Weather Service expects the weather system to move toward the central and northern Plains on Sunday night, potentially affecting the Upper Midwest by Monday, Oct. 26, and Tuesday, Oct. 27. Local officials in the Southwest continue to monitor river levels, with San Juan County officials describing the region as an active disaster zone.
