Very good ski quality can be found. Pay attention to recent wind loading, and the effects of the sun during the day.

Summary

Weather Forecast

Variable cloudiness with high temperatures at valley bottom locations. Good over night freezing is and very little for precipitation is expected.

Snowpack Summary

The recent storm snow has settled into a soft slab condition, especially in the alpine where the wind has gusted into the moderate to strong range over the past 36 hours. Below tree line, warm temperatures have created moist surface conditions especially on solar aspects.

Avalanche Summary

Several slabs have been observed on lee slopes in the alpine. This seem to have run in the past 24-36 hrs. Below tree line there has been a number of moist loose snow avalanches on solar aspects.

Confidence

Timing or intensity of solar radiation is uncertain

Problems

Storm Slabs

There has been several avalanches observed running in the recent storm snow. Avalanche control produced 30 - 70 cm thick slab results on NE aspects.

Caution in lee and cross-loaded terrain near ridge crests.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

1 - 3

Loose Wet

This problem will start to become a regular occurrence as the intensity of the sun increases and valley bottom temperatures climb.

Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.Avoid ice climbs that are exposed to steep rocky terrain on solar aspects.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood

Possible

Expected Size

1 - 2
