A top up of snow and decent refreeze tonight will mean for good travel in the morning. Expect to find fresh windslab in exposed areas in the alpine and treeline. Pay attention to signs of instability, dig down and be patient for proper spring to arrive.
Up to 10cm of new snow has been redistributed by moderate to strong winds from the southwest, building new windslabs in the lees of ridgecrest and into open treeline features.
A cornucopia of persistent weak layers in the midpack can be found as facets on polar aspects and sun crusts on solar aspects.
Explosives control in a permanently closed area at Marmot Basin on Sunday reported triggering a size 2 persistent slab, stepping down to basal weaknesses.
MIN report from Sunday at Hilda observed whumpfing in multiple locations above treeline.
No recent reports of natural avalanche activity but still be vigilant and make careful assessments.
Don't forget to post avalanche observations to the MIN.
Up to 5-10cm of new snow around the Icefields area sits on top of a variety of surfaces - crusts on solar aspects & BTL and old wind pressed/ slab on exposed northerly aspects.
The snowpack below 1800m is in a daily melt-freeze cycle. The mid-pack above this elevation consists of multiple layers of sun crusts or facets. Depth hoar and basal facets make up the base of the snowpack.
Tuesday will be another day of clouds with some isolated flurries. Alpine temperatures are forecasted to be a high of -3 °C. Ridge winds will be from the southwest (10-25 km/h) and freezing level rising to 1800 metres during the day. Tuesday evening will see freezing levels drop back down to valley bottom.
Wednesday will see similar conditions of clouds and chance of isolated flurries and an alpine high of -4°C.
