Avalanche Forecast

Moderate - Uncertainty is due to the limited number of field observations.

Monday Night: Cloudy with isolated flurries, trace to 5 cm. Alpine temperature -6 C. South-southwest wind, 35 km/hr gusting to 70 km/hr.

Tuesday: Cloudy with isolated flurries, 5-10 cm. Alpine temperature -6 C. West wind, 25-45 km/hr.

Wednesday: Mainly cloudy. Alpine temperature -7 C. Southwest wind, 30-50 km/hr.

Thursday: Snow, 10-35 cm. Alpine temperature -4 C. Southwest wind 50-85 km/hr.

There have been no recent reports of avalanche activity.

15-30 cm of snow fell in the region early last week and flurries continue to contribute to totals. Moderate south-southwesterly winds have since developed wind slabs, especially around ridge features and into the alpine. 

Reports suggest there are 2 buried layers of surface hoar in the upper snowpack - one down 15-25 cm below the new snow, and another down 25-40. Where wind has scoured the snowpack, a crust from November is at or near the surface. In leeward terrain, this crust is 40-80 cm deep, and may include surface hoar in sheltered openings up to treeline.

Older crusts can be found deeper in the snowpack and are generally breaking down. In areas with a relatively thin snowpack, the base of the snowpack likely consists of weak faceted grains.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
• Make observations and assess conditions continually as you travel.
