Avalanche Forecast

Fair - Forecast snowfall amounts are uncertain on Sunday

Expect lingering snowfall (up to 10cm) on Monday morning as Sunday's storm tapers-off. A clearing trend is forecast for late Monday and Tuesday. By Wednesday, a strong Pacific low will deliver another round of moderate snowfall. Ridgetop winds will remain moderate to strong from the southwest on Monday, decreasing somewhat on Tuesday, and then becoming strong and southwesterly with Wednesday's system Freezing levels should hover around 600m for the forecast period.

There were a few recent reports of wind slabs to size 2 occurring on north and east-facing terrain at treeline and above. The wind slabs formed in response to strong southwest winds and snowfall on Thursday and Friday. Continued snowfall and strong westerly winds on Sunday and Monday morning will likely spark another round of wind slab activity.

Just before the weekend, 10-20cm of snow and strong SW winds built reactive wind slabs in exposed lee terrain. More snow and wind on Sunday will add size and destructive potential to the developing wind slab problem. Below the recent snowfall, you'll find a variety of interfaces including older wind slabs, hard crusts, surface hoar, and/or surface facets. At the base of the snowpack, weak facets may be found. Cornices are reported to be large and potentially unstable.
