Grand Junction, Colorado – Rain and snow showers are expected to develop this evening, bringing hazardous travel conditions to mountain passes along and north of Interstate 70.
According to the National Weather Service in Grand Junction, anomalous moisture moving into western Colorado will trigger precipitation beginning late Tuesday, with the heaviest snowfall forecast overnight.
Forecasters said snow levels are expected to remain above 9,000 feet, meaning lower valleys may see rain while higher elevations receive accumulating snow. Mountain areas along the I-70 corridor, including Vail Pass and Glenwood Canyon, are expected to experience the most significant impacts.
Gusty mountain winds may accompany the system, leading to reduced visibility and slick road conditions, particularly after sunset. Snowfall is forecast to continue through early Thursday morning, with totals measured through 5 a.m. Thursday.
Hazardous travel is most likely over higher terrain and mountain passes north of I-70, while communities such as Rifle and areas near U.S. Highway 550 could also see periods of snow at elevation.
Drivers are advised to use caution, reduce speeds and prepare for changing road conditions overnight.
The system may be especially relevant for late-night commuters, freight drivers and students traveling across mountain corridors.
Conditions are expected to gradually improve after daybreak Thursday as precipitation tapers off.
