In sintesi

Avalanche conditions are expected to remain touchy. Weak basal snow and a deep storm layer should be given time to settle. Watch for windslabs in exposed locations. Conservative route selection is advised through the weekend. JPK

Weather Forecast

Cold arctic air has become established in the forecast area with temperatures expected to dip to -27C. Overnight cooling may wring a centimeter or two more snow out of the previous air mass, but the clearing trend should be firmly established on Saturday.

Snowpack Summary

40 to 60 cm of storm snow on facets, surface hoar, and rain crust have produced a touchy snow pack at all elevations. Shooting cracks and whoomphing are common throughout the forecast area. Windslabs can be expected on all exposed aspects.

Avalanche Summary

Poor visibility limited avalanche sightings today, but the ski areas are reporting widespread natural activity to size 2.5.
