US: New Travel Alert as Colorado to Experience Frosty Weather, Storm and Arctic Cold

Saturday, January 18, 2025

A Winter Weather Advisory has been issued for the Denver metro area and surrounding regions, warning of heavy snow and dangerous Arctic cold conditions beginning Friday night through Saturday evening. The advisory includes travel disruptions, particularly along the I-70 Mountain Corridor, as ski traffic faces significant delays due to icy roads and poor visibility.

Weather Overview

Friday:

The initial Arctic cold front will sweep into Colorado on Friday afternoon, bringing snow across the mountains and valleys north of I-70. The snow will expand southward by evening, with the heaviest snowfall expected overnight. Accumulations of 3 to 6 inches in Denver and 4 to 10 inches near the foothills are forecast, creating slick road conditions during peak traffic hours.

Saturday:

Light snow showers will linger throughout the day, accompanied by frigid temperatures brought by the Arctic front. Although snowfall will taper off, the icy road conditions will persist, complicating travel in both urban and mountainous areas.

Sunday into Monday:

Another wave of light snow is predicted for Sunday night, adding to the already accumulated snow. Commuters on Monday morning should prepare for potentially hazardous road conditions and increased delays.

Pavement and Travel Conditions

Friday Evening:

As snow begins Friday afternoon, initial accumulations on pavement may melt due to residual heat in lower elevations, such as Denver and the foothills. However, as temperatures rapidly drop, melted snow will freeze into treacherous icy patches, particularly on untreated surfaces. Patchy blowing snow across the plains may further reduce visibility. Wind speeds are expected to ease later in the evening, but slick roads will persist.

Saturday and Sunday:

The extreme cold will inhibit melting, keeping roads icy throughout the weekend. I-70 Mountain Corridor and other mountainous routes will face periodic flurries and light snow, sustaining hazardous conditions. Despite ongoing plowing and road treatments by the Colorado Department of Transportation (CDOT), low temperatures will reduce the effectiveness of deicing efforts.

Traffic Impacts

Friday Afternoon and Evening:

CDOT predicts heavy ski traffic along the I-70 corridor, with significant delays anticipated during the evening. A “double peak” pattern is expected, with a westbound surge in the morning and increased congestion during evening hours as residents head to the mountains for the weekend. Key choke points such as Floyd Hill and Eisenhower Tunnel are likely to experience gridlock.

Saturday Morning and Evening:

Saturday morning will bring slow-moving traffic as congestion builds along key mountain routes. I-70 hotspots like Georgetown and Vail Pass will see delays exacerbated by fresh snow showers. Evening traffic heading back to Denver will also be impacted, with icy patches and reduced visibility posing risks to drivers.

Sunday and Monday:

Sunday’s ski return traffic will peak midday, with high volumes leading to slower travel times. The continuation of snow showers into Sunday night will add an additional layer of complexity for commuters on Monday morning. Motorists should plan for prolonged delays and icy roads, particularly during late-morning traffic peaks.

CDOT’s Recommendations for Safe Travel

CDOT urges drivers to take the following precautions:

• Plan Ahead: Monitor weather updates and road conditions on CDOT’s website and social media channels.
• Equip Your Vehicle: Ensure vehicles are equipped with winter tires or chains, particularly for mountain travel.
• Drive Cautiously: Reduce speeds and increase following distances to account for icy patches and sudden stops.
• Be Prepared: Carry emergency kits, including blankets, food, and water, especially for travel along mountain routes.
• Avoid Peak Hours: Whenever possible, travel outside of peak ski traffic times to minimize delays.

Economic and Recreational Impacts

Colorado’s winter weather not only poses challenges to transportation but also impacts the state’s lucrative ski tourism industry. The I-70 Mountain Corridor serves as a vital artery for weekend ski traffic, and delays can significantly disrupt tourism revenue. Resorts and local businesses dependent on skier visits may experience reduced attendance due to hazardous conditions.

However, for many visitors, the snowy conditions add to the allure of Colorado’s winter landscapes. Resorts are preparing to welcome skiers eager to hit the slopes despite the travel challenges.

Looking Ahead

With snow continuing through Monday, travelers are encouraged to remain vigilant and prioritize safety. The Winter Weather Advisory serves as a reminder of the dynamic and unpredictable nature of Colorado’s winter season. By planning ahead and following CDOT’s recommendations, both locals and tourists can navigate the challenges while enjoying the beauty of the snow-covered Rockies.
