Denver, CO – Drivers across the Denver metropolitan area and portions of Colorado's Front Range face hazardous travel conditions Tuesday morning, Oct. 27, as dense fog reduces visibility to less than a quarter mile in some locations. A Dense Fog Advisory remains in effect until 9 a.m., potentially affecting commuters traveling along Interstate 25 and surrounding highways.
According to the National Weather Service Denver/Boulder office, the advisory covers the Interstate 25 corridor and adjacent plains, including metro Denver, Lincoln County and eastern Elbert County.
Visibility could fall below one quarter mile at times , making it difficult for motorists to see approaching vehicles, intersections and roadway hazards.
The advisory includes portions of the Denver metropolitan area and eastern Colorado plains, where fog may develop or persist during the early morning commute.
Communities near Denver, Bennett, Limon and surrounding areas should prepare for reduced visibility, particularly along open stretches of highway.
Interstate 25 is a primary concern for Tuesday morning travelers.
Motorists using I 25 through the Denver region should allow additional time to reach work, school or other destinations.
Other major routes crossing the affected area, including Interstate 70 and Interstate 76, may also encounter reduced visibility where dense fog develops.
The National Weather Service advises drivers to slow down, increase following distances and use low beam headlights.
High beam headlights should be avoided because their light can reflect off fog droplets and make visibility worse.
The Dense Fog Advisory is scheduled to expire at 9 a.m. MDT Tuesday, Oct. 27.
However, visibility conditions can vary significantly over short distances, meaning drivers could encounter clearer stretches of roadway followed by areas of sharply reduced visibility.
Travelers should remain especially cautious near highway interchanges, rural intersections and locations where traffic speeds change unexpectedly.
Residents planning early morning travel are encouraged to check current road conditions and National Weather Service updates before departing.
The advisory highlights a potentially dangerous visibility hazard rather than a confirmed highway closure, and motorists should follow any additional instructions issued by local transportation officials.
