    Lingering wind slabs are likely becoming challenging to trigger, but may still exist in steep terrain below ridgecrests.

Avalanche Summary

No recent avalanches have been reported, but observations are limited this time of year. If you do head into the backcountry please submit a MIN report!

Moderate

Snowpack Summary

The upper snowpack has been heavily wind affected, with hard wind slabs found on all aspects. Sustained cold temperatures have likely softened the snow surface in wind-sheltered terrain. Roughly 70 to 90 cm can be found at treeline in White Pass. Upwards of 100 cm may exist in wind-loaded areas. The lower snowpack consists of soft, sugary facets and a crust near ground level.

Weather Summary

Sunday night

Partly cloudy, no precipitation, 20 km/h wind from the northwest, alpine temperatures around -6 °C.

Monday

Mostly cloudy, no precipitation, 20 to 30 km/h wind from the northwest, mild inversion with alpine temperatures around -2 °C.

Tuesday

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
