Avalanche Forecast

High

No new avalanche was reported or observed in the last 24 hours. Old evidence of small loose wet avalanches (size 1) was observed on steep southwest-facing slopes at Mines Madeleine.

A melt/freeze cycle occurred on Thursday night above 500 m of elevation. Icy surfaces (with a supportive crust up to 5 cm) are found on all alpine slopes, except perhaps the steep south-facing slopes. At treeline, conditions were classic corn snow with soft surfaces. Below treeline, the warm weather of the last 3 days and lack of significant refreeze at night is keeping the snow wet and making conditions rather sticky and slow (mashed potatoes snow). Melting is happening fast and the height of snow varies from 50 cm (valley) to 130 cm (mid-mountain).

Forecast for the Chic-Chocs ridges and summits.

Synopsis: A high-pressure ridge will keep supporting sunny skies and warming temperatures until Tuesday.

Friday evening and night: Clear. No precipitation. Moderate northwest wind at 35 km/h. Alpine low of -6 C. Freezing level at valley bottom.

Saturday: Sunny with cloudy periods. No precipitation. Light southwest at 20 km/h. Alpine high of +2 C. Freezing level rises to 1250 m.

Sunday: Sunny with cloudy periods. No precipitation. Light southwest wind at 25 km/h. Alpine high of +6 C. Freezing level steady at 2500 m.

Monday: Cloudy with sunny periods. No precipitation. Light southwest wind at 25 km/h. Alpine high of +8 C. Freezing level rises to 3000 m.

• Be alert to conditions that change with elevation and sun exposure.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
• The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
• Cornices become weak with daytime heating or solar exposure.
