Backcountry Avalanche Advisory

As of Wednesday, March 10


Alpine: Considerable Thursday, High Friday

Treeline: Considerable through Friday

Below Treeline: Moderate through Friday

(Please note that "Backcountry" refers to any areas outside the Ski Area Boundary)

Travel Advisory: Heavy precipitation and strong winds will build deep soft slabs by Thursday morning. These wind-affected slabs will be sitting over small surface hoar and areas of hard crust and are expected to be easily- triggered. This trend of precipitation, wind and easily-triggered size 2 slab avalanches is expected to continue through the weekend.

Avalanche Activity: Soft slabs were developing in the alpine on Sunday to 10 cm. Expect slabs to size 1 today on most alpine aspects, easily triggered with the weight of a skier. These slabs are likely to grow to over 30 cm by Thursday morning.

Snowpack: A melt-freeze crust on sun-affected slopes was initially buried on Sunday, while north aspects remain winter-like. Surface hoar of three-five mm is protected below the March 7th new snow and is expected to be an excellent sliding layer for the forecast storm snow.

Weather: A cool series of storms will bring significant precipitation and strong winds through Saturday. Another system is expected late on Sunday after a weak break on the weekend.
