Avalanche Forecast

Moderate - Uncertainty is due to the speed, direction, or duration of the wind and its effect on the snowpack.

Sunday night: Cloudy. Possible trace of snow. Light to moderate southeast wind. Alpine low around -8 °C.

Monday: Snowfall 3-10 cm. Light wind building to strong south in the afternoon. Alpine high around -6 °C.

Tuesday: Snowfall 5-20 cm. Strong south wind. Alpine high around -5 °C. Freezing level 800 m. Freezing level 800 m.

Wednesday: Snowfall 5-15 cm. Strong south wind. Alpine high around -6 °C. Freezing level 800 m.

Recent avalanche activity has been limited to loose dry sluffing around size 1.

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. 

A surface crust may exist on steep solar aspects. As winds start to pick up on Monday, any remaining soft snow of the recent 30-40 cm in the White Pass area will likely be redistributed into wind slabs in wind exposed terrain. This snow sits over a wind pressed snowpack, or an older crust on steep, south facing slopes. 

The lower snowpack is thought to be well protected by the dense layers above, and it is unlikely that avalanches will be triggered on weak, sugary crystals near the ground at this time.

• Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
• Wind slabs are most reactive during their formation.
• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
