    New snow and wind may form reactive wind slabs in pockets of high elevation terrain. At treeline and below, the snowpack is below threshold for avalanche activity. Use extra caution as many early-season hazards exist.

Confidence

Poor - Due to the number of field observations

Weather Forecast

Overview: Light flurries may persist on Saturday. By Sunday, a weak ridge will develop bringing mainly sunny skies and a cool northwesterly flow.Friday night and Saturday: Up to 10 cm of new snow on Friday night tapering to light flurries on Saturday / Moderate to strong southwest winds overnight Friday becoming light on Saturday / Freezing level at about 1100mSunday: A mix of sun and cloud / Freezing level at valley bottom / Light northwest windsMonday: Light snowfall / Moderate to strong southwest winds / Freezing level at about 1100m

Avalanche Summary

No avalanches have been reported. With snowfall and wind forecast for Friday night, we may see a round of wind slab activity in pockets of high elevation terrain.

Snowpack Summary

Welcome to winter! As we begin our forecasting season we are working with very limited field data. If you`ve been playing in the snow, please tell us what you`ve seen by sending your observations to [email protected] reports indicate there is currently not enough snow to ski or ride at treeline and below. Pockets of skiable terrain exist in the alpine, although access to these areas will likely be a challenge and many early season hazards exist. These pockets of high elevation terrain are the areas most likely to have an avalanche problem, especially as the new slab deepens with ongoing snowfall. Any new snow, which may exist as a wind slab, may have a poor bond with old surfaces (crusts, facets) which formed during the recent dry spell.
