Denver, CO – Snow covered mountain passes, black ice and sudden highway closures can create dangerous conditions across Colorado. As winter weather awareness efforts continue Tuesday, October 27, residents are being reminded that winter storms can disrupt travel, damage power infrastructure and threaten communities from the Rocky Mountains to the eastern plains.
According to the National Weather Service NWS , freezing rain occurs when liquid precipitation freezes on contact with surfaces at or below freezing. Although heavy snow, strong winds and blizzards are more common Colorado winter hazards, freezing rain and icy pavement can also create dangerous travel conditions.
How Dangerous Can Colorado Winter Storms Become? Even a thin coating of ice can make bridges, overpasses and untreated roads extremely slippery.
Heavy snowfall and strong winds can reduce visibility, create deep snowdrifts and force temporary highway closures. Wet snow and ice may also damage trees and power lines.
Drivers traveling Interstate 70, Interstate 25, Interstate 76 and U.S. Highway 285 should monitor forecasts and road conditions, particularly near mountain passes and exposed sections of the eastern plains.
Colorado's high elevations can experience winter conditions while lower elevation communities remain comparatively mild.
Ice Jams and Winter Flooding Risks River ice jams develop when accumulated ice restricts water flow, potentially causing flooding upstream.
Prolonged freezing temperatures can produce ice along some Colorado waterways, especially in colder mountain valleys and northern river corridors.
Winter thaws, rapid snowmelt and heavy precipitation may increase flooding risks when ice blocks river channels.
Communities along the South Platte, North Platte, Yampa and Colorado river systems should monitor official river forecasts during periods of warming.
How Colorado Residents Can Prepare Before severe winter weather arrives, residents should take several precautions:
Keep blankets, food, water and emergency supplies in vehicles. Carry appropriate tires or traction devices when required. Charge phones and prepare for possible power outages. Check highway closures before mountain travel. Avoid unnecessary driving during blizzard conditions or freezing precipitation. Stay away from downed power lines and unstable river ice. Residents can monitor road conditions through COtrip and weather forecasts from the NWS Boulder office , NWS Pueblo office and NWS Grand Junction office .
Winter weather awareness efforts continue through Saturday, October 31 , emphasizing preparation before heavy snow, dangerous road ice and winter flooding threaten Colorado communities.
