Colorado Mountain Weather Alert: Snow Intensifying Tonight Between Glenwood Springs and Grand Junction Near I-70 Beavertail Tunnel
GLENWOOD SPRINGS, COLORADO — Rain and snow are becoming more widespread across western Colorado tonight, particularly along the Interstate 70 corridor between Glenwood Springs and Grand Junction. Forecasters say lower elevations along the western slope may see periods of rain while higher mountain elevations transition to heavier snowfall as the system strengthens overnight.
The weather activity is being closely monitored along I-70 just east of the Beavertail Tunnel, where mountain snow is beginning to increase and visibility conditions may quickly deteriorate for travelers crossing the higher elevations.
Rain at Lower Elevations, Snow in the Mountains
Weather conditions across western Colorado are showing a classic elevation split, with rain falling at lower elevations while snow becomes dominant in the mountains.
Communities along the western slope, including areas closer to Grand Junction, may see rainfall during the evening hours. Meanwhile, higher terrain between Glenwood Springs and the Beavertail Tunnel along I-70 is expected to transition to more persistent snowfall as colder air settles into the mountains.
As temperatures continue to drop overnight, snow coverage may expand across the higher passes and surrounding peaks.
Snow Becoming More Widespread Overnight
Meteorologists say the snowfall will gradually become more widespread tonight, particularly across mountain areas along the I-70 corridor.
Travelers passing through the region late tonight could encounter periods of moderate snow, especially near the higher elevations east of Glenwood Springs.
The camera imagery from the corridor already shows steady snow falling in the area, indicating that the storm system is beginning to take hold in the mountains.
Travel Conditions May Become Difficult
Drivers traveling between Grand Junction and Glenwood Springs should prepare for potentially challenging driving conditions as snow intensifies overnight.
Snowfall combined with reduced visibility may lead to slick road surfaces along mountain stretches of I-70, especially near the Beavertail Tunnel and surrounding elevations.
Mountain weather can change rapidly, and even brief bursts of heavier snow can create hazardous conditions for vehicles traveling through the region.
Western Colorado Weather Pattern Continues Tonight
The weather system responsible for the rain and snow is expected to continue influencing the western slope overnight as moisture spreads across the mountains. While lower valleys may mainly experience rain, higher elevations along the interstate corridor could see accumulating snow as the night progresses.
Officials continue monitoring conditions across the region, particularly along Interstate 70 between Glenwood Springs and Grand Junction, where mountain travel may be affected as snowfall continues to develop overnight.
