Avalanche Forecasts are for use by experienced backcountry travelers in uncontrolled sidecountry and backcountry terrain. These forecasts and conditions do not apply to open, in-bounds terrain at ski resorts, which is subject to avalanche control by local resort ski patrol.
Tricky conditions exist with buried weak layers. Expect wind slabs to form, adding load to a weak snowpack
Stick to conservative terrain and avoid large features at treeline and above
By Sunday evening, up to 20 cm of new snow is expected. This new snow will fall over a crust on south facing slopes, or over settling snow that overlies previous weak surfaces of crusts, facets or wind affect.
Roughly 50-60 cm of snow now sits above a widespread crust from late January. Weak grains like facets or more isolated surface hoar may be found above this crust. This problematic layering remains a concern with recent avalanche activity and snowpack tests showing reactivity. As minimal snowfall is forecast this layer is not expected to produce natural avalanches, but human triggering remains very possible.
Wind slabs continued to show reactivity to human triggers on Friday with up to size 1.5 reported.
Activity is expected to increase on Sunday as snow and wind develop fresh slabs over weak snow surfaces.
