Avalanche Forecast
Regions: Corner Brook, Gros Morne, Long Range Mountains, Northern Peninsula.
Fresh wind slabs are likely to build as snow accumulates Sunday through Tuesday. Size and likelihood of triggering a wind slab will progressively increase as snow gradually accumulates.
Confidence
Moderate
Avalanche Summary
No recent avalanches have been reported.
Snowpack Summary
Fresh snow will be accumulating above hard and wind affected snow in exposed areas Sunday through Tuesday. Primarily southwest wind will likely redistribute the new snow into north and east facing slopes.
Snow depths in the Long Range Mountains average about 80 cm in wind-sheltered areas and are much more variable in wind-exposed areas. The snowpack structure is strong and bonded.
Cornices have been forming along northeast-facing ridges.
