Points saillants

The potential remains to trigger deep slabs on steeper terrain especially in thinner snowpack areas. Lots of good riding can be found on moderate angled terrain. JBW

    These slabs are fairly isolated now, but could cause a deep step down avalanche if triggered.

    Thin areas and steep terrain that has not  yet avalanched should be avoided. Thicker moderate angled terrain  with low consequences would be a good choice.

Weather Forecast

The upper warm ridge will continue to deflect any major precipitation and keep temperatures moderate at least through the weekend. This will give a slowly stabilizing trend to the snowpack.

Snowpack Summary

Surface hoar growing. Midpack pencil with no significant shears. Sudden collapse at base in old DH and on top of Crust in the very hard range. Potential for human triggering in thin areas.

Avalanche Summary

No new avalanches observed.
