Avalanche Forecast

Today, we expect new snow and south winds will form triggerable slabs. Watch for building slabs, especially on lee terrain features, and in the west of the region where storm totals are expected to be greater.

On Saturday, several size 1 slab and loose dry avalanches were triggered by skiers in steep terrain. Check out this MIN report from Saturday.

Up to 30 cm of new snow will likely be blown around by south winds today. Expect to find deeper and more reactive deposits in the west of the region.

This snow overlies previously wind-affected surfaces at upper elevations. Below 1100 m expect that it falls on a crust.

The remainder of the snowpack is strong, with numerous hard melt-freeze crusts.

Treeline snow depths generally range from 50 to 150 cm. Snow depth diminishes rapidly below 1000 m, these elevations received more heavy rainfall and a crust has likely formed. Traveling on skis is almost impossible below treeline.

Sunday Night

Cloudy with up to 5 cm snow, west alpine wind 30 to 50 km/h, freezing level around 600 m.

Monday

Cloudy with 15 to 30 cm snow, greatest in the west, south alpine winds 40 to 60 km/h, freezing level rises to 1000 m by 4 pm.

Tuesday

Cloudy with up to 20 cm snow, south alpine winds 80 to 100 km/h, freezing level 1200 m.

Wednesday

Partly cloudy with no precipitation, north alpine winds 20 to 40 km/h, freezing level drops to 700 m.

• Watch for fresh storm slabs building throughout the day.
• Storm slab size and sensitivity to triggering will likely increase through the day.
• Seek out sheltered terrain where new snow hasn't been wind-affected.
