Recent snowfall and southwest winds have formed wind slabs in north and east facing terrain features in the alpine and treeline.
Take care around ridgelines where wind slabs may linger.
Minimize your exposure to sun affected slopes. Sunshine and rising temperatures will increase the potential for wet avalanches.
Recent snowfall and southwest winds have formed wind slabs in north and east facing terrain features in the alpine and treeline.
Expect wet slab and wet loose avalanches on steep, sun affected slopes as temperatures rise. Avalanches are expected to initiate easily on the crust below.
No new avalanche activity was reported on Thursday. Earlier in the weak cornice falls triggered slabs on the slopes below, on north facing alpine slopes.
5-10 cm of settling storm snow sits over old snow surfaces, and a crust on sun affected slopes. On north facing slopes near ridgelines, deeper deposits of snow can be found - while south facing slopes may hold hard, wind pressed surfaces or a crust.
Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.
