Wintery conditions continue through Monday. The following days will gradually be warming up with sun and less overnight freezes. WATCH OUT if the sun pokes out increasing trigger-ability particularly on steep solar aspects.
Maligne valley received 10cm with gusting moderate winds whipping the snow around. Be suspicious of pockets of wind slab resting on a slippery crust at ridgetops or alpine features. Small slides can have nasty consequences if it involves terrain traps. The Icefields received less snow.
Avoid direct exposure to cornices as the temperatures rise. Cornice failures are a bad situation anytime.
This problem is unreactive in the morning and increases sensitivity with afternoon warmth and sun. It is critical to evaluate the degree of overnight freeze and relate it to how quickly this problem can activate during the day.
Sunday's Maligne-Bald Hills patrol noted no new avalanches but visibility was limited to below mountain tops. No patrol occurred to the Icefields' area.
Up to 10cm of snow with variable wind effect overlies a strong mid-pack above 2400m on shaded aspects. Sunny aspects, and everywhere below 2400m, starts in the morning as a supportive surface crust that breaks down with solar input and rising daytime temperatures.
