Weather Forecast
Monday night: Flurries, up to 10 cm by Tuesday morning. Alpine temperature -10 C, southwest wind 35-50 km/hr
Tuesday: Snow and flurries, 10-30 cm accumulating through the day. Alpine temperature -5 C, southwest wind, 30-55 km/hr.

Avalanche Summary
The likelihood of triggering storm slab avalanches will increase through the day as new snow accumulates and is impacted by wind.
Snowpack Summary
Snow and flurries have fallen on a faceted upper snowpack and previously wind-affected surfaces. Below the old wind-affected snow, a layer of surface hoar (feathery crystals) may be found in sheltered areas around treeline. In these areas old, stubborn wind slabs may still be reactive where they overly the weak surface hoar on a crust.
A variety of crusts from late October are buried deeper in the snowpack (down 50-100 cm).
Problems
Storm Slabs
Avalanche danger will rise through the day as new snow accumulates. With increasing winds, expect to find more reactive deposits of storm snow around ridge lines and in wind-loaded areas.
