Should You Drive Colorado’s High Mountain Passes on October 14–15, 2026?
Postpone nonessential high-country travel and check current route conditions before any necessary trip.
Postpone a nonessential drive through Colorado’s high mountain passes during the October 14–15, 2026, weather window. The National Weather Service advisory for affected high terrain calls for 6–12 inches of snow and hazardous, snow-covered mountain travel. It is a high-country advisory—not necessarily a warning for every Colorado or Denver-area road—and is valid from 2:00 p.m. EDT Wednesday, October 14, through 8:00 a.m. EDT Thursday, October 15.
If the trip is necessary, check the exact route on CDOT’s COtrip map immediately before departure for current conditions, closures, incidents, and traction restrictions, or call 511. Conditions can change during the advisory, and the available information does not establish a specific closure or restriction for every route.
