Avalanche Forecast

Moderate

Recent explosive avalanche control and natural cornice fall has produced numerous slab avalanches up to size 2 in north through east facing alpine terrain.

Looking forward: Avalanches on buried weak layers may be difficult to trigger, but if one is triggered, it is likely to be large and destructive.

New snow falls on a variety of surfaces.

Below 1900 m and on solar aspects, a surface crust overlays up to 25 cm of snow that sits on a widespread melt-freeze crust.

Above this and on north aspects, the new snow falls on wind redistributed snow from predominantly southwest wind.

A weak layer of preserved surface hoar or facets from late January is buried 80 to 130 cm. This weak layer remains a concern where there is no thick, supportive crust under the recent snow.

The lower snowpack is generally well-settled and strong.

Sunday Night

Mainly cloudy, with up to 20 cm of snow. 30 to 60 km/h southwest ridgetop wind. Treeline temperature around 0 °C.

Monday

Mainly cloudy, with possible flurries. 20 to 40 km/h southwest ridgetop wind. Treeline temperature around 0 °C.

Tuesday

Mainly cloudy, with up to 5 cm of snow. 15 to 25 km/h southwest ridgetop wind. Treeline temperature around 0 °C.

Wednesday

Mainly cloudy, with up to 5 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature +1 °C.

• Be aware of the potential for large avalanches due to buried weak layers.
• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
