Summary
Weather Forecast
Tuesday: 10cm of snow expected overnight, partially cloudy. Moderate winds at ridgetop . Alpine temps High -3. FL valley bottom.
Wednesday: Partially cloudy no precip expected today. Alpine temps High - 8. Moderate W winds. FL valley bottom.
Thursday: Partially cloudy with PM flurries. Alpine temps High - 6. Moderate SW winds. FL valley bottom
Snowpack Summary
5-15cm unconsolidated snow overlies a 20-40cm windslab ALP/TL atop a 10cm Dec 4 rain crust with facets below. A 20-60 cm thick Nov melt freeze crust complex completes the snowpack to ground. BTL has just reached threshold in some places. HS at TL is 100 - 170 cm deep.
Avalanche Summary
No new avalanches observed with good visibility. Observations in this area are still limited, if you go out into the mountains please share your observations on the Mountain Information Network.
Confidence
Due to the number of field observations
Problems
Wind Slabs
A 20 to 40cm windslab sits on the Dec rain crust.
- Use caution in lee areas. Recent wind loading have created wind slabs.
- Use caution on steep lee and cross-loaded slopes
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
No avalanches observed on this layer today, however the potential still exists with a large enough trigger.
- If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: All aspects.
Elevations: Alpine, Treeline.
