A size 2 slab avalanche occurred on Friday in the north of the region and resulted in a fatality. The avalanche occurred on a northeast aspect at treeline, More details will follow as they are released by the RCMP.

Up to 50cm of new snow and wind have created potent new storm slabs which are likely to be most reactive in wind-exposed terrain. These heavy accumulations add to the 25 to 55cm of snow which overlie the weak surface hoar layer which was buried on February 12th. The additional weight of the new snow and wind affect is expected to add reactivity to this persistent weakness which remains a primary concern for professionals in the region. This interface has also shown reactivity on southerly aspects where a sun crust formed during the period from February 8th-11th. There are older weak layers (surface hoar, crusts on solar aspects, facets) that are now buried down around 60-80 cms and also at about 110 cms. These layers have been unlikely to trigger by skiers, but they may still be sensitive to large loads like avalanches in motion or cornice fall.
