Our seasonal friend, mountain snowfall, returns this week as Colorado braces for an October storm that’s likely to impact travel along I-70. As cold air moves in, snow will arrive in the high country on Wednesday.

Several inches have been forecast above 9,500 to 10,000 feet, with the greatest potential for mountain travel problems late Wednesday into Thursday morning. If you are leaving the Western Slope and heading over the mountains, this storm will be worth watching.

Snowfall is expected to impact conditions on I-70 over Vail Pass.

These are the routes to check before you go, not necessarily the confirmed trouble spots. Before you depart Grand Junction to cross the Continental Divide, review current road conditions, restrictions, and weather alerts.
