Kernpunkte

Today the avalanche danger is CONSIDERABLE on all steep upper elevation slopes where dense slabs of wind-drifted snow can be found on all aspects because of the various wind directions. Some drifts will be obvious, others hidden beneath snow, and they will tend to break above you, not at your feet. The danger for wind drifts is MODERATE at mid and low elevations, including the foothills. Wind-sheltered slopes will still have good skiing and riding, where the main issue will be sluffing of the new snow in steep terrain.

    Wind drifts can be found today at all elevations and on all aspects. While most widespread at the upper elevations, you will also find drifts at the lower elevations of the foothills and near the canyon mouths. Yesterday’s unusual northeasterly wind direction will have drifted snow onto unusual slopes, cross loading across gullies and depositing drifts well off the ridge lines. If you’re going hiking or walking your dog in the foothills or on low elevation trails, look for and avoid the smooth, rounded wind drifts, especially on steep slopes and in gullies.

    To complicate matters, there are older buried wind slabs that will be difficult to detect. Created by a variety of wind directions earlier this week, they are on a variety of aspects and around mid slope terrain features. Approach all steep slopes with caution - these hard wind drifts can not be ski cut and will break above you.

Recent Activity

The only avalanches reported yesterday were small, new snow drifts released with ski cuts. I imagine there could have been a few naturals avalanches overnight due to the strong winds.

Snow and Weather

Yesterday afternoon’s northeasterly wind event is the headline, with plumes and blowing snow from the summits to the valley floor. Along the Ogden area mountains ridge lines, average speeds of 30 to 40 mph, gusting in the 60s, occurred late afternoon into the night. Speeds were highest near the canyon mouths, with 70 mph gusts at the mouth of Farmington Canyon.

Skies have cleared and temperatures plummeted - they’re in the single digits below zero, and will only warm into the single digits above zero to the low teens. The northeasterly winds have decreased, and should remain in the 10 to 20 mph range, with the high ridge lines averaging 20 to 30, with gusts to 40. Very wind sheltered slopes will still have soft, powdery snow, most likely at the mid to low elevations.

Additional Info

We are also tracking the shallow snowpack at the mid and low elevations. Here, the entire snowpack is weakening, and will be a concern in the future. There is also a buried rime crust in places that could be an issue. Riming on trees, also now buried beneath a few inches of snow. L. Fortin and B. Brandt photo.
