Avalanche Forecast
Regions: Glacier.
The snowpack is stabilizing with cooling temps, but triggering an avalanche is possible, especially in loaded pockets near the top of a slope.
Saturday's forecast is for 10cm and light wind, if exceeded the hazard could quickly rise to considerable.
Weather Forecast
Cool temps and a weak pulses of precipitation this weekend.
Tonight: Cloudy. Freezing level to valley bottom. Alpine low -10*C. Ridge top winds light SW.
Sat: Flurries (5-10cm). Alpine high -8*C. Light gusting moderate W winds.
Sun: Cloudy with flurries. Low -17*C. High -15*C. Light - mod W winds.
Mon: Mix of sun and cloud. Low -18*C. High -15*C.
Snowpack Summary
A spring snowpack in early December? Below tree-line you will find a supportive crust at or near the surface of the snowpack. At treeline this crust is buried by 10-15cm of fresh snow. In the alpine, this fresh snow (up to 30cm) overlies firm surfaces from the storm early in the week. The mid and lower snowpack is rounded and well bonded.
Avalanche Summary
No new natural avalanche observed or reported on Dec 03.
The massive storm on Dec 01 produced widespread avalanches, both natural and artillery triggered, up to size 3.5, many reaching valley bottom.
Confidence
Due to the number and quality of field observations
Avalanche Problems
Storm Slabs
Fresh storm slabs may be found in exposed areas at tree-line and in the alpine. These overly a crust at treeline, and unreactive thick wind/storm slabs or icy bed surfaces from previous activity in the alpine.
- New snow will require several days to settle and stabilize.
- Watch for fresh storm slabs on exposed lee slopes at and above treeline.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2.5
Loose Dry
Expect sluffing in steep terrain.
- Use caution above cliffs and terrain traps where small avalanches may have severe consequences.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 1.5
