Travel is looking to be troublesome in the High Country this weekend - even the metro will see some trouble Friday evening.

As a winter storm system moves in, a Hazardous Weather Outlook has been issued focusing on the south-southwest area of the High Country for the weekend. The worst will face drivers heading over the highest mountain passes, according to the Colorado Department of Transportation.

The National Weather Service said that the worst of it will face southwest and south-central Colorado. Due to their forecast, CDOT is pretreating roads starting on Friday.

Once snow starts settling on the roads, snow plows will be pushed out to get rid of all the snow.

One thing travelers in the south and south-central high country should be aware of are maintenance delays on roadways. CDOT says they'll likely start maintenance operations this weekend and continue them on into Tuesday.

Travelers should keep a keen eye out for maintenance equipment on or near roadways - and watch for maintenance crews and avalanche crews.
