New wind slabs will remain easy to trigger for the next day or so until the winds ease and the new snow has a chance to bond. Sunday and Monday should allow for good travel and ski conditions but pay attention to daytime heating as the skies clear.
Summary
Weather Forecast
Moderate to strong west winds with light snowfall will continue through Saturday night before easing up on Sunday morning. Freezing levels will creep higher Sunday and higher still Monday with increasing solar influence as a ridge and clearing skies arrives on Sunday afternoon.
Snowpack Summary
5cm of new snow over a melt freeze crust on all aspects at tree line, and up to 2900m on solar aspects. 20-50cm of snow over the last week in the alpine with moderate west winds creating soft slabs and rapid cornice growth. At tree line and above the mid-pack is a 120cm+ firm slab overlying weaker basal facets in much of the region.
Avalanche Summary
Reports of a couple skier triggered wind slabs in the alpine at Bow Summit and Cathedral Peak on Friday as the winds increased. Propagation up to 100m was reported. On Saturday local ski areas were seeing rapid cornice growth and were able to ski cut small wind slabs in lee areas throughout the day. No new naturals observed but visibility was poor.
