Avalanche Summary

Earlier this week a small wet loose cycle occurred in the new surface snow. Avalanches to size 2 were observed on all aspects.

Snowpack Summary

Very warm daytime temps and limited overnight refreezes will keep the snowpack isothermal on all aspects at all elevations. The January melt-freeze crust is buried up to 100cm. Alpine and Treeline midpack is well settled and overlies basal facets and depth hoar. Most places the snowpack is now moist to ground.

Weather Summary

Friday-Sunday

Temps are forecast to get un-seasonably hot over the weekend. Alpine temps up to +15 will be possible. Skies are forecast mostly clear with no precip expected. Winds will be light to moderate.
