Avalanche danger will increase to HIGH as new snow and wind form fresh and reactive storm slabs.
20-40 cm of new snow is forecast to fall with strong wind in the White Pass area Tuesday. Fresh storm slabs are likely to run naturally during the storm.
Monday night: Snowfall 5-15 cm. Wind building to strong southeast. Alpine low around -6 °C.
Tuesday: Snowfall 10-30 cm. Strong southeast wind. Alpine high around -5 °C.
Wednesday: Snowfall 5-15 cm. Moderate to strong south wind. Alpine high around -7 °C.
Thursday: Snowfall 3-10 cm. Moderate to strong southeast wind. Alpine high around -5 °C.
Recent avalanche activity has been limited to loose dry sluffing around size 1. Looking forward, natural and rider-triggered storm slabs will be likely during the storm on Tuesday.
If you head out into the mountains, and you have photos to share, conditions to report on, or just some stoke about the good riding, consider making a post on the Mountain Information Network.
20-40 cm of new snow is forecast to fall amid strong wind Tuesday in the White Pass area. The new snow falls over settling snow from the previous storm, wind slabs in exposed areas and a sun crust on steep solar aspects.
A couple of sun crusts exist in the upper snowpack but none have been identified as layers of particular concern. The lower snowpack is thought to be well protected by the dense, wind-pressed layers above, and it is unlikely that avalanches will be triggered on weak, sugary crystals near the ground at this time.
