Be aware of cracking around your skis as you approach tree line. This is a good indicator of wind slabs.

Any avalanche has the potential to trigger the basal facets, resulting in large avalanches.

Weather Forecast
The winds are expected to be 30km/hr from the SW on Friday with mostly a cloudy sky and a temperature of -6c. For Saturday, winds will be light with a mix of sun and cloud and warming up to -1c in the alpine. No snow in the horizon for the weekend.
Avalanche Summary
One natural size 1 was observed in the Commonwealth area. Another size 1 below treeline (gully side wall feature) skier controlled that failed on the basal facets.
Snowpack Summary
Wind and basal facets are the themes this year so far... Another windy day today has added to the wind slabs in the alpine and open areas at tree line. Northerly and Easterly aspects and lee feature are most likely to have more snow and soft slabs because of the winds. Some whumphing was felt in the trees in the Commonwealth area today. This is a reminder that the bottom half of the snowpack is weak and consists mostly of facets. Good skiing can be found on moderate angles and the forecasters are staying off of the steeper lines and away from large slopes. Any avalanche that occurs has the potential to step down to the basal facets creating an even larger avalanche.
