Points saillants

Strong north winds and cooler temperatures will create poorly bonded windslabs on south facing features.

    Strong north winds at higher elevations will continue to rearrange the windslab pattern from NE to more south facing slopes. Recent additional snow in the Icefields area will be moved to lee features.

    Large avalanches could occur where smaller avalanches or cornice failures trigger a collapse in deep basal facets. A strong midpack is bridging this layer, except near wind exposed terrain.
