Moderate
Avalanche Summary
There have been a few reports of small (size 1-1.5) loose dry avalanches from steep terrain over the past few days.
Otherwise, no avalanche activity has been reported since last weekend.
With more snow, wind, and warm temperatures in the forecast, we anticipate natural avalanche activity in the coming days.
Snowpack Summary
New snow is accumulating across the region, burying various surfaces, including old wind-affected snow in exposed terrain, sun crusts on south-facing slopes, and weak surface hoar or faceted grains in sheltered areas.
Layers from dry conditions in January are found at varying depths within the upper 100 cm of snow. These include weak faceted snow, sun crusts on south-facing slopes, and surface hoar in shaded terrain.
The mid and lower snowpack is generally well-settled and strong.

Terrain and Travel Advice
- Pay attention to the wind; once it starts to blow, sensitive wind slabs are likely to form.
- Avalanche danger is expected to increase throughout the day.
- Be aware of the potential for large avalanches due to buried weak layers.
Problems
Wind Slabs
New snow and moderate southwest wind will build fresh slabs on lee slopes.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
Weak layers from recent dry, clear, and cold conditions persist within the upper 100 cm of snow. These layers could become more reactive with the added stress of new snow and warming temperatures.
Aspects: All aspects.
Elevations: All elevations.
