Severe Winter Storms and Historic Flooding Threaten Colorado

A potent weather system is delivering heavy snow and severe flooding risks across southwestern Colorado, prompting winter storm warnings and mandatory evacuations in multiple counties. The National Weather Service reported that areas above 10,000 feet in the San Juan Mountains are under winter storm warnings, with forecasts calling for up to 18 inches of snow and wind gusts reaching 50 mph.

The severe weather combines heavy mountain snowfall with historic rainfall threatening river basins across the region. Flood warnings remain active for the upper Rio Grande Valley and the San Juan Mountains, with the San Juan River at Pagosa Springs cresting at levels well above historic records. Officials warn that the unfolding situation poses a severe danger to residents in low-lying areas.

Archuleta County sheriff's officials issued urgent warnings for residents to evacuate immediately, stating that response capabilities during the height of the storm will be severely restricted. "Do not wait for the water to rise. Do not wait for another warning. Leave now," the office stated. Mandatory evacuation orders also cover residents in Rio Grande and Mineral counties along the South Fork of the Rio Grande River, as well as parts of Conejos County.

The ongoing flooding follows severe weather that struck southwest Colorado less than two weeks prior, damaging hundreds of homes and numerous roadways. The new storm threatens to push river levels significantly higher than previous historic benchmarks, including the legendary October 1911 flood that devastated Pagosa Springs. National Oceanic and Atmospheric Administration gauges indicate that major flooding levels are expected across several southern river basins through Tuesday.

In the higher elevations, winter storm warnings issued by National Weather Service offices in Grand Junction and Pueblo remain in effect through Monday afternoon. The northwest and southwest San Juan Mountains expect 12 to 18 inches of snow, while the eastern ranges anticipate 8 to 14 inches alongside powerful wind gusts. Mountain passes, including Wolf Creek Pass, Red Mountain Pass, and Lizard Head Pass, face extremely hazardous travel conditions characterized by blowing and drifting snow.

Transportation officials have issued specific guidance for motorists navigating the treacherous mountain passes. The Colorado Department of Transportation urges drivers on Wolf Creek Pass to utilize low gears and monitor vehicle brakes carefully to prevent overheating along the steep grades. Meanwhile, safety crews continue to manage avalanche control systems along Red Mountain Pass to mitigate highway risks during the storm.
