Avalanche Forecast

High

• We are confident due to a stable weather pattern.

Cornice failures were observed on Tuesday along the highway corridor and by neighbours. Cornices have been weakened by temperature fluctuations and solar inputs.

Dry, loose avalanches up to size 1 were noted from steeper Alpine terrain on all aspects.

A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river. Check out pics from this exceptional avalanche cycle in the MIN Reports. Watch for huge debris piles in valley bottom.

Expect widespread sun crusts. Sheltered features hold dry, loose snow lying on a firm crust. Wind slabs might be lingering in exposed terrain.

A series of crusts formed in March are present down 50-150 cm.

Below the storm snow, a strong crust exists up into treeline. Another crust from early March is down 70-150cm.

Travel can be challenging below treeline with frozen tree bombs and huge avalanche debris from last week's super storm.

Spring weather is forecast with sun, cloud and flurries.

Tonight Cloudy. Alpine low -3°C. Ridge wind SE 15km/h. Freezing level (FZL) 1800m

Thurs Cloudy, isolated flurries, trace amounts. Alp High -2°C. Wind NW 20km/h. FZL 1900m

Fri Cloudy with sun, isolated flurries, trace amounts. Alp High -4°C. Wind SW 25-35km/h. FZL 1800m

Sat Cloudy, scattered flurries, trace amounts. High -3°C. Wind SW 15-35km/h. FZL 1900m

• Loose avalanches may start small, but they can grow and push you into dangerous terrain.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
