Weather Forecast

Mix of sun and cloud Friday with a chance of showers in the afternoon. Moderate winds from the west will make it feel cooler. Stronger winds in the alpine to 50km. Clearing for the weekend and back to seasonal norms.

Snowpack Summary

Strong Southwesterly winds have created pockets of windslab and obliterated exposed areas at upper elevations. Weak basal facets are bridged by a strong mid-pack in most areas at treeline and above.

Avalanche Summary

Natural cornice failures continue and many more are waiting their turn to fall.

Confidence

The weather pattern is stable on Saturday
