Avalanche Forecast

Good

Mainly sunny for Thursday then cloudy with sunny periods on Friday and Saturday, with isolated light flurries possible in the northern part of the region. Freezing as high as 1600 m on Thursday then up to 2100 m for Friday and Saturday, but down to valley bottoms overnight. Light southwesterly winds are expected for Thursday before increasing to moderate westerlies on Friday.

Reports from Tuesday include several dry loose sluffs in steep terrain and thin soft wind slabs reacting to slope cuts with minimal propagation.

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.
