The storm forecast has intensified compared to snowfall accumulation mapping that was published on Monday, now calling for snow in the range of 48 to 60 inches in the southwest region of Colorado.

From Tuesday morning through Friday morning, some of the mountains around Durango and Pagosa Springs could get up to 60 inches – five feet – of snow in the ‘most likely’ snowfall scenario. The ‘high-end’ snowfall forecast, which has a one-in-10 chance of happening, shows that this deeper snow could be even more widespread, including mountains found directly south of Silverton.

Looking at the rest of the state, the eastern half of Colorado should mostly get skipped during this storm, including the I-25 metro area.

Meanwhile, it’s not just the southwest region that’s expected to get hit hard – it’s just expected to get hit the hardest. Mountains near Grand Junction, Steamboat Springs, Glenwood Springs, Aspen, and Westcliffe could see two feet of snow or more.

Thanks to strong winds that are expected to accompany this storm, visibility in areas where flakes are falling is expected to be limited. Expect drifting snow, potential whiteout conditions, and slick roads. Delays and closures are likely, especially when it comes to mountain passes, such as Wolf Creek Pass and Red Mountain Pass.
