Cool temperatures are expected to preserve problems for a few days until the new snow has had time to settle.
Saturday night's strong N winds and snowfall (higher amounts in the front ranges) has built fresh slabs on S aspects. Older windslabs exist on N aspects, and may be bonded by now.
Sensitivity of this layer may have increased on slopes loaded by recent wind and snow. Crusts in upper snowpack and deeper facet layers warrant further investigation.
Activity could increase with presence of intense sun particularly on steep Southerly aspects.
Monday will be clouds, sun, and flurries, trace of snow, treeline -5C, light winds, and 1500m freezing level. Tuesday will be similar, low -8 and high -5C, light winds, and freezing level 1700m. Wednesday may bring 7cm of snow.
15cm of snow on Friday in the Icefields, the same Saturday at Maligne from an upslope storm. The snow was reverse loaded by Strong N-NE winds and overlies several crusts/facet layers in the upper snowpack. Stubborn windslabs can be expected on most aspects in the alpine and treeline. A faceted midpack layer on shady alpine slopes remains a concern.
Good visibility at Maligne range observed one recent size 2.5 persistent slab in an alpine bowl, E aspect, convex shaped terrain, likely initiated by morning sun. No other activity was noted but the patrol was before noon. No new activity was noted on an icefields parkway road patrol.
