Weather Forecast

A very weak system is expected to produce light precipitation on Thursday. The wind will be relatively light. These factors will have little effect on the danger rating. However, at the local level short bursts of solar energy will have an impact on the snow surface.

Snowpack Summary

Wind slabs up to 35cm deep are present in immediate lee areas of the alpine. The mid pack and base of the snowpack are well settled and well bonded overall. Expect isothermal conditions at low elevations.

Avalanche Summary

No avalanches observed or reported today.

Avalanche Problems

Wind Slabs

Windslabs are still sensitive to human triggering on lee features at treeline and above. Cornices will also be a concern with the new snow and wind.

Use caution in lee areas. Recent wind loading have created wind slabs.
Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

Watch locally for sun affect as lower elevation slopes may be isothermal Tuesday.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
