Weather Forecast
Cloudy overnight with developing northwest winds and alpine temperatures around -10. Overcast with snow starting late morning. Most areas should see 5-10 cm, and areas in the south and east may see enhanced precipitation as the arctic air dives south and collides with some warmer Pacific air. The snow should end by Tuesday morning when skies clear and the high pressure re-builds over the interior. Wednesday should be clear and cold with light winds.
Avalanche Summary
No new avalanches reported.
Snowpack Summary
Variable amounts of dry facetted surface snow and pockets of surface hoar can be found above the mid-February crust. New melt-freeze crusts can be found on solar aspects at all elevations. The mid-pack is well settled. 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.
