A Flood Warning remains in effect for Archuleta County, Colorado, until 3:45 PM MDT on October 23, 2026. Excessive rainfall has caused ongoing urban and small stream flooding across the county. Between 1.5 and 3 inches of rain have fallen since Thursday, with an additional 0.5 to 1 inch possible. Forecasted thunderstorms for this afternoon increase the threat of flash flooding.

Mandatory evacuations were ordered by the Archuleta County Sheriff's Office on Thursday afternoon for low-lying, flood-prone areas along the San Juan, Rio Blanco, Navajo, and Piedra rivers. This order took effect at 2:24 PM. Authorities warned that rising water levels and swift currents could make it impossible for rescuers to reach those who remain. The San Juan River is projected to reach flood stage.

Colorado Governor Jared Polis declared a disaster emergency on Thursday evening, around 8:30 PM, in response to flooding affecting Archuleta, La Plata, Montezuma, and several other counties. Governor Polis later declared a disaster emergency in 11 counties across southwestern Colorado due to heavy rain and flooding. The Town of Pagosa Springs also declared a Local Disaster Emergency on October 22, 2026, citing significant damage to roads, bridges, culverts, and other public infrastructure.

Flooding has led to widespread impacts, including several damaged structures in Archuleta and Saguache counties. Numerous roads across the county are closed due to flooding. U.S. Highway 160 has major closures, with sections between Mile Markers 134 and 135 completely shut down. Travel on Highway 160 between MM 134 and MM 144 is strongly discouraged due to hazardous water accumulation. Other closed highways include U.S. 550 Red Mountain Pass and U.S. 160 Wolf Creek Pass. Rescuers were attempting to reach two people and three dogs stranded in a motor home in floodwaters on Friday.

Archuleta County advised residents to expect localized flooding and unsafe swift-water conditions through Friday, October 23, 2026. The county also urged people to avoid walking, playing, or camping near rivers.
