There may be another light dusting of snow, with small wind slabs forming, but really there is little change to speak of.
Summary
Confidence
Good - The weather pattern is stable
Weather Forecast
Friday: A mix of sun and cloud with a slight chance of flurries. The freezing level is around 1800-2000 m and ridge winds are light or moderate from the W. Saturday: A mix of sun and cloud. The freezing level remains near 1800 m and winds ease to light. Sunday: Mainly sunny. The freezing level jumps to a little over 2000 m and wind could rise to moderate SW by the end of the day.
Avalanche Summary
Recent reports include several dry loose sluffs in steep terrain, and thin soft wind slabs reacting to slope cuts with minimal propagation. Explosive testing also resulted in one cornice fall that did not trigger a slab on the slope below.
Snowpack Summary
Roughly 5-10 cm of recent storm snow adds to the variable amounts of dry facetted snow on top of the mid-February crust with associated buried surface hoar in sheltered areas, or more recent melt-freeze crusts on sun-exposed slopes. The late-Jan crust/surface hoar layer can be found about a metre below the surface in deeper snowpack areas. The mid-January surface hoar, can be found below that. These layers have gained significant strength, and chances of triggering these weaknesses have decreased dramatically. However, triggering may be possible with a large input such as cornice fall, or an avalanche stepping down, especially on slopes that see a lot of sun.
Problems
Wind Slabs
Fresh touchy wind slabs may be lurking in a variety of places. Although not expected to be large, they could take you for a ride.
Be cautious as you transition into wind affected terrain.>Avoid travelling in areas that have been reverse loaded by winds.>Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.>
Aspects: All aspects.
Elevations: Alpine, Treeline.
