Travel in avalanche terrain is not recommended. Avalanches in the new snow are very likely.

New storm slabs will form on Friday and Saturday. Human-triggered avalanches will be very likely on steep slopes, and natural avalanches are expected anywhere with more than 30 cm of new snow.

Ongoing snow and wind will build reactive storm slabs over the weekend, with storm totals reaching 30 to 50 cm by Saturday afternoon. The new snow will bond poorly to the old snow surfaces, which includes melt-freeze crusts on sun-exposed slopes, large surface hoar or facets on shaded slopes, and wind-affected snow in exposed terrain at ridgelines. The lower snowpack is strong and bonded.

Friday Night

Cloudy with 15 to 25 cm of snow. 50 to 70 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Saturday

Cloudy with 5 to 15 cm of snow. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Sunday

Cloudy with 5 to 15 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Monday

Mix of sun and cloud 2 to 5 cm of snow. 10 km/h east ridgetop wind. Treeline temperature -20 °C.

• Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Only the most simple non-avalanche terrain with no overhead hazard is appropriate at this time.
• Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
