Avalanche Forecast

A naturally triggered, size 2 storm slab avalanche was reported on Thursday, occurring on a steep, west-facing moraine feature in the alpine.

A cornice failure observed on Thursday did not propagate any weak layers on the north-facing, alpine slope below.

Despite the low danger rating, the likelihood of triggering an avalanche will increase throughout the day with warming and strong solar radiation expected.

A melt-freeze crust has likely formed on the surface in all but north-facing alpine terrain. This crust will weaken and transition to wet snow with daytime warming and solar radiation.

Wind-affected dry snow remains in north-facing, alpine terrain.

Friday Night

Sunny. 10 to 30 km/h east ridgetop wind. Treeline temperature -5 °C. Freezing level 1300 m.

Saturday

Sunny. 10 to 30 km/h southeast ridgetop wind. Treeline temperature +1 °C. Freezing level 2200 m.

Sunday

Cloudy with 0 to 10 cm of snow at higher elevations. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 1700 m.

Monday

Mostly cloudy. 10 to 30 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1900m.

• Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
• Be alert to conditions that change with aspect and elevation.
• Be alert to conditions that change throughout the day.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
