Variable winds are redistributing recent storm snow, keeping rider-triggered avalanches possible in wind-loaded terrain.

Moderate

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

No avalanche activity has been reported since last weekend. Over the weekend, numerous explosive and naturally triggered storm or wind slab avalanches occurred, up to 2.5 on various aspects and elevations.

While natural avalanche activity is becoming unlikely, rider-triggered avalanches will remain possible.

Recent storms have delivered 20 to 50 cm of snow, burying a thin melt-freeze crust at elevations around 2000 m and below. Variable winds have redistributed this snow, creating wind-affected surfaces in exposed, high-elevation terrain.

The mid and lower snowpack is characterized by multiple crust layers, with moist snow persisting near the base in some areas.

Snow depths at treeline generally range from approximately 100 to 200 cm.

Monday Night
Mostly clear skies. 40 km/h west ridgetop wind. Treeline temperature -7 °C.

Tuesday
Mostly sunny. 40 to 60 km/h west ridgetop wind. Treeline temperature -5 °C.

Wednesday
Sunny. 50 to 70 km/h west ridgetop wind. Treeline temperature -3 °C.

Thursday
Mostly sunny. 40 km/h southwest ridgetop wind. Treeline temperature -3 °C.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Avoid lee and cross-loaded slopes at alpine and treeline elevations.
• Recent wind has varied in direction, so watch for wind slabs on all aspects.
