Avalanche Forecast

While no avalanche activity has been reported, we expect a natural avalanche cycle to be occurring, particularly in regions receiving higher snowfall amounts.

Observations remain very limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network

New snow continues to form reactive wind and storm slabs at the surface. The recent snow has buried a variety of surfaces, including old wind-affected surfaces, along with a chance of surface hoar in wind-sheltered terrain or lower elevations.

A crust formed in early November may be present in the mid-snowpack, with possible faceted crystals above or below it.

The lower snowpack is largely comprised of several old melt-freeze crusts and potentially large depth hoar crystals in some areas.

Snowpack depth at treeline is roughly 100 to 150 cm, with snow depths decreasing rapidly at lower elevations.

Friday Night

Cloudy with 2 to 10 cm of snow. 10 to 30 km/h west ridgetop wind. Treeline temperature -12 °C.

Saturday

Cloudy with 10 to 20 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -12 °C.

Sunday

Mostly cloudy with 2 to 5 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Monday

Mostly cloudy with some local areas to the north forecast to receive as much as 30 cm of snow, with only a trace elsewhere. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -1 °C.-

• Watch for fresh storm slabs building throughout the day.
• As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
• Closely monitor how the new snow is bonding to the old surface.
• Be cautious of buried obstacles, especially below treeline.
