Avalanche Forecast

High

On Thursday, several natural wind slab avalanches were observed on solar aspects up to size 2.5. These were likely triggered by daytime warming.

We expect to see a widespread natural avalanche cycle over the next few days. Avoid avalanche terrain and exposure from overhead hazards (open slopes, cornices) as avalanches could run full path.

40 cm of recent storm snow is settling quickly with warm temperatures. At treeline and above, the storm snow has been redistributed by previous winds, leaving widespread wind-affected surfaces in exposed terrain. Moist snow surfaces will extend into the alpine with rising freezing levels.

A thick and hard widespread crust that formed in early February is buried about 50 to 110 cm deep. This crust has a layer of facets above it in many areas.

The eastern portion of this region is much shallower with a highly variable and wind-affected snowpack.

Friday Night

Mostly clear skies. 20 to 30 km/h west ridgetop wind. Alpine temperatures are around +2°C. Freezing level between 2500 and 2800 m.

Saturday

Sunny. 10 to 25 km/h southwest ridgetop wind. Alpine temperature high near +6°C. Freezing level continues rising to 3200 m.

Sunday

Sunny. 30 to 50 km/h southwest ridgetop wind. Alpine temperature high near +5°C. Freezing level around 2800 m.

Monday

Sunny. 20 to 30 km/h west ridgetop wind. Alpine temperatures high of +2°C. Freezing level around 2500 m.

• Avoid runout zones of avalanche paths on solar aspects, avalanches could run full-path if triggered.
• Choose gentle slopes without steep terrain above.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
• A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
