Highlights

Give the new storm snow time to settle out before venturing into steep terrain, as this represents a significant new load on the snowpack.

    New windslabs will have formed in the storm and will sit on old windslabs from extreme winds earlier in the week. Beware of lee features and steep gullies.

    New snow (30–50 cm) will form a slab that will remain triggerable by skiers/riders even after the storm has passed. Cooling temperatures may help reduce sensitivity to triggering, but that depends on how quickly the snowpack bonds to underlying layers. It's best to give the new snow time to settle.

Weather Summary

Over the weekend, we are expecting a relatively stable weather with seasonal temperatures, cloudy skies and light southwesterly ridge top winds. Parker Ridge area may receive a trace to a few centimeters of snow.
