A powerful winter storm is set to sweep across Colorado, Idaho, and Washington early next week, bringing heavy snow and potentially hazardous travel conditions. Starting Monday, mountain passes and highways, including Colorado’s I-70, Idaho’s U.S. 95, and Washington’s I-90, will likely see significant disruptions as snowfall intensifies.
According to NOAA’s Weather Prediction Center, the storm will begin Monday afternoon, impacting higher elevations first. Snow accumulation is expected to exceed 0.25 inches of liquid equivalent, leading to dangerous road conditions, especially in mountain regions. Drivers are urged to carry chains, check road conditions frequently, and avoid non-essential travel through affected areas.
In Colorado, snowfall along I-70 is expected to begin late Monday, continuing into Tuesday. Heavy snow could create treacherous conditions in the Rockies, with potential road closures through high-elevation passes. Travelers are advised to plan for delays and monitor weather advisories.
Idaho will see similar conditions, with U.S. 95 likely to experience hazardous snow accumulation beginning Monday. Northern parts of the state, particularly near the Rockies, are expected to receive the heaviest snowfall. Motorists should prepare for slippery roads and changing weather patterns.
Washington’s Cascades are also in the path of the storm, with heavy snowfall expected to impact I-90 from Monday through Tuesday. Mountain snow could disrupt travel along this key route, and local authorities recommend caution when traveling through high elevations.
The storm will bring a prolonged period of cold temperatures, with snow showers lingering into midweek. Residents across these states should prepare for winter conditions and stay updated on local forecasts.
