Summary
Weather Forecast
Sun: Periods of wet snow mixed with rain in the townsite. 10-15 cm snowfall at Cameron Lake. Alpine high of +4 with freezing level at 1800m. Moderate SW wind with extreme gusts up to 120km/h
Mon: Mainly cloudy with scattered flurries. 2-5cm of snow with freezing level at valley bottom. Moderate SW wind with strong gusts
Tues: A mix of sun and cloud
Snowpack Summary
10-20cm of new snow is expected on Sunday with strong- extreme SW wind. This will create fresh wind slabs over a variety of old surfaces including a thick crust that exists to ridgetop (except on high N aspects) or old wind slab on N-E alpine slopes. Mid snowpack is well consolidated with the lower half composed of dense facets & decomposing crusts
Avalanche Summary
No recent avalanche activity reported.
Confidence
Intensity of incoming weather systems is uncertain on Sunday
Problems
Wind Slabs
Fresh wind slabs will be most reactive during the storm on Sunday / Monday. Periods of intense wind transport may cause wind slabs to form low in start zones.
- Use caution in lee areas. New snowfall mixed with wind loading is creating Wind Slabs.
Aspects: North, North East, East, South East, West, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
This problem is specific to lower elevations on Sunday as rainfall will stress the snowpack below freezing level. Be mindful of your overhead hazard and avoid travel through large avalanche paths.
- Use extra caution on solar slopes or if the snow is moist or wet.
Aspects: All aspects.
Elevations: Below Treeline.
