Backcountry Avalanche Advisory


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

As of Wednesday, Feb. 11 at 7:07 a.m.
Avalanche Danger

Alpine: Moderate through Friday
Treeline: Moderate through Friday
Below Treeline: Low through Friday

Travel Advisory:
30 cm of fresh snow have blanketed a variable surface of wind and temperature crusts. Sunny skies and daytime warming will stress the surface layers through mid-week, especially on solar exposures. Below this old surface the very strong mid snowpack is bridging over the weak facetted base.

Avalanche Activity: Widespread avalanche activity was seen in the new snow layers on Monday in the alpine. These slabs were thin and were not stepping down into older layers although it may be possible in rocky, shallow areas.

The crust/facet combination that formed with prolonged cold temperatures in early December is now buried up to 200 cm below a stiff more coastal snowpack. Recent stability tests within the basal weakness are variable and inconsistent. The new snow is sitting over various old crust surfaces depending on aspect. The surface hoar that is buried below treeline now has an added load and may propagate.

A ridge of high pressure is expected to move in over the South Coast resulting in clear skies for the rest of the week.
