Avalanche Forecast

On Wednesday, skiers controlled triggered two wet loose avalanches. There was also a report of an accidentally triggered storm slab avalanche with no involvement.

A large storm slab avalanche was reported on the 5th in the Tetrahedron. We anticipate more of these types of avalanches are likely to occur due to this last storm.

There is potential for deep storm slabs and wind slabs to slide on a buried crust, producing large and destructive avalanches.

Moderate southerly winds will have redistributed the up to 70 cm that has fallen this week. Southerly winds have redistributed this snow into wind slabs at higher elevations. Expect to see moist or wet snow

A hard crust can now be found in sheltered, approximately 60 to 80 cm deep. The rest of the mid and lower snowpack seems strong and consolidated.

Snowpack depths are reaching 230 cm at treeline.

Thursday Night

Cloudy with late-day sunny periods, up to 5 cm accumulation in the morning, and more snow starting later in the evening at higher elevations, winds southerly 65 km/h, treeline temperatures at 2 C, and cooling.

Friday

Cloudy, up to 25 cm accumulation at a higher elevation throughout the 24-hour period, winds southerly 40 km/h, treeline temperatures -3 C.

Saturday

Cloudy, trace accumulation, winds southwest 25 to 30 km/h, treeline temperatures - 5 C.

Sunday

Cloudy, up to 8 cm accumulation with rain at lower elevations, winds southwest 40 to 50 km/h, treeline temperatures -2 C.

• Good day to make conservative terrain choices.
• Use increased caution at all elevations. Storm snow is forming touchy slabs.
• Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
• As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
