Highlights

The avalanche danger is LOW in the backcountry. Stable snow conditions are found on most slopes and avalanches are unlikely. However, people still might trigger small slab avalanches on isolated drifted slopes steeper than 30°.

  • Use normal caution, go one at a time and keep and eye on your backcountry partners. Regularly check all of your rescue equipment and practice using it with your companions.
  • Heavy snow and drifting from strong west winds from a quick hitting winter storm tonight and tomorrow will elevate the avalanche danger.
  • Very low wind chill values will create dangerously cold conditions in the mountains tonight and tomorrow.

    Significant drifting occurred last week, elevating avalanche danger in exposed terrain. Some hard and soft wind slabs formed on weak surface snow and may still be unstable. Although unlikely, avalanches could still be triggered remotely or from a distance.

    • Avoid corniced slopes and stiffer drifts on steep slopes near ridges and in and around terrain features like cliff bands, sub-ridges, mid-slope break-overs, and gully walls.

Recent Activity

Saturday, skiers near Logan Peak in Mill Hollow remotely triggered a 8" deep and 60' wide wind slab avalanche that ran around 500 vrt'. Report is HERE

Snow and Weather

We've been finding really good shallow powder conditions in sheltered northerly terrain and on lower angled slopes, especially at mid and lower elevations. But it's getting a bit sparse, and it's time for a refresh. Winds last week damaged the powder in exposed terrain and on many upper elevation slopes, and sun melted and crusted the surface in sunny terrain. Winds at the 9700' CSI Logan Peak weather station are blowing from the southwest at 18 mph this morning. The Tony Grove Snotel at 8400' reports 29° F and just under 8 feet, (95 inches) of total snow.

Today, we'll see increasing clouds and southwesterly wind speeds, with high temperatures at 8500' around 28°F.

Tonight, expect snow to fall heavily at times, with 5 to 9 inches of accumulation and widespread areas of blowing snow in the early morning hours. Low temperatures around 2° F and strong and gusty winds from the west-northwest will drive wind chill values as low as -18° F.

Tomorrow, snow and drifting or blowing snow are expected to continue in the morning, with 3 to 7 inches of additional accumulation possible. High temperatures around 13° F, and gusty west winds will create wind chill values around -21°F

Expect snow to taper off Tuesday, with gradual clearing, some sun, and continued cold weather through the work week.

Additional Info

Skiers remotely triggered this avalanche of wind drifted snow in Mill Hollow yesterday. The avalanche ran around 500 vrt' and would have been a dangerous ride if anyone had been caught. People could trigger similar avalanches on drifted upper elevation slopes today.
