Avalanche Forecast

Moderate

• We are uncertain due to a limited number of field observations.

We do not have any recent reports of avalanches, but suspect a natural cycle occurred over the weekend with rain, warm temperatures, and strong winds.

Despite the cooler temperatures, avalanches are likely with ongoing snow and wind forming slabs atop a widespread crust.

Around 40 cm of snow has accumulated along with southwesterly alpine winds. The snow overlies a crust from last weekend's rain that is likely present at most elevations, except possibly in isolated high alpine areas.

On north aspects, 80 to 150 cm below the surface, two persistent weak layers exist (buried in late January and early February) and contain facets over a crust. It remains uncertain whether the recent warm conditions had any stabilizing effect on the reactivity of these layers.

Monday Night
Mostly cloudy. 15 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Wednesday
Mostly cloudy. 15 to 25 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -8 °C.

• Watch for fresh storm slabs building throughout the day.
• Avoid freshly wind-loaded terrain features.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
