Weather Forecast

Today will be a break in the weather between storm fronts. Expect a mix of sun and cloud with isolated flurries that won't produce significant snowfall. Freezing levels will remain low(400m) giving an alpine high of -11deg. Wind will be from the Southwest 15-25kph. Incoming storms Sunday night and Tuesday could produce 15-25cms of new snow.

Snowpack Summary

10cm of new snow fell in the last 24 hrs burying the Dec15th interface. This layer is the one to watch develop. It is widespread surface hoar found at all elevations and is LARGE (30-40mm) in sheltered areas at treeline. The new snow also buries crusts on S & W aspects and windslab in the alpine. So far the Nov crusts (down 60-90cm)are bonding well

Avalanche Summary

No new avalanches observed.

Confidence

Forecast snowfall amounts are uncertain

Avalanche Problems

Loose Dry

After a long dry spell, 10cm of new snow has fallen on a crust on solar aspects and widespread surface hoar. Small skier triggered slides are very likely today and will run fast & far!
Be cautious of sluffing in steep terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Likely - Very Likely

Expected Size: 1 - 2
