The avalanche hazard has bumped up slightly in the alpine from the sustained north and easterly winds.
Summary
Weather Forecast
Continuing clear and cold for the next couple of days. Winds should remain light from the North and East at ridge-top, occasionally gusting moderate.
Snowpack Summary
5-10cm of soft snow overlies hard snow surfaces of sun crust on steep solar aspects and wind slab at higher elevations. This new snow has seen some wind affect and has bonded poorly to the layers beneath. A new surface hoar layer is down 5cm at lower elevations. The mid pack is well settled. Cold weather has begun faceting the snowpack.
Avalanche Summary
No new avalanches observed yesterday.
Confidence
Due to the number and quality of field observations
Problems
Wind Slabs
Expect to see some thin slabs on S and W aspects in the alpine and exposed tree-line elevations, due to cold Arctic winds blowing from the N and E. These slabs will be stiffer with the cold weather, and have not bonded well to the older surfaces.
Caution in lee and cross-loaded terrain near ridge crests.Be cautious as you transition into wind affected terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
