Watch for winslabs developing in open lee areas and near ridgecrests.

Weather Forecast

Up to 15 cm has been modeled for the system passing over tuesday night. Accompanying winds will create windslabs.

Snowpack Summary

Some wind and fresh snow will create new windslabs near ridge crests and in open lee areas. Dry snow is still found on high north aspects. Many areas exhibit a cohesive midpack over the basal facets, while other thin areas have weak facets to the ground.

Avalanche Summary

No new avalanches observed or reported.

Confidence

Intensity of incoming weather systems is uncertain

Avalanche Problems

Loose Wet

With reduced solar inputs and a cooling temperature trend forecasted this week, the loose wet problem will be less of a concern. Any unforseen increases in temps/solar or significant rain could quickly increase the likelihood of this problem.

Aspects: South East, South, South West.

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 1 - 2

Wind Slabs

Use caution in lee areas. Recent wind loading have created wind slabs.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
