Confidence

Poor - Forecast snowfall amounts are uncertain on Saturday

Overnight and Saturday: 3-5 cms overnight with moderate Westerly winds and freezing levels going back to the valley bottoms. Another 5 cms during the day (mostly in the South of the region) combined with light Westerly winds and alpine temperatures about -7.0.Sunday: Unsettled weather with overcast skies and strengthening Westerly winds and strong gusts.Monday: Continued unsettled weather.

Avalanche Summary

No new avalanches reported.

Snowpack Summary

There is a lot of variability in the recent storm snow amounts and the amount of wind effect across the region. The Harvey Pass area has seen a lot of wind. Thin stiff wind slabs have formed, and fetch areas have been stripped. The Crossing Creek area has seen less wind and about 20 cms of new snow. It was snowing all day Friday, so we expect the storm snow to continue to accumulate. The storm snow has not been reported to be reacting as a cohesive slab.
