Weather Forecast

Very cold temperatures continue for the forecast period. Although forecast winds are light, windchill is a big factor. Winds are forecast to pick up from the north on sunday.

Snowpack Summary

Little Prairie 63cm. Summit Lake = 100-120 cm . Cold temps have prevented slab development in the storm snow. Windslabs built during storm are present on reverse locations (northeast aspects) and could possibly be skier triggered. The facet/melt freeze interface from Dec 1 has also not settled out yet.

Avalanche Summary

Sluffng out of very steep terrain.

Confidence

Wind effect is extremely variable
