Avalanche Forecast

Good

Friday: Expect mostly sunny skies, with a chance of high, thin cloud. Winds should be light from the north and alpine temperatures should reach -4.Saturday & Sunday: Expect the ridge to settle in. Sunny skies, light northerly winds and alpine temperatures reaching -1 each afternoon.

We have reports of natural, explosive and rider triggered windslabs up to size 2.5 failing on northwest through east facing terrain. These are failing predominantly at treeline and in the alpine. Remote and accidental triggering have been observed. The south end of the region has seen the larger releases with wider propagation; at times linking terrain around ridge features. These areas have also seen storm slab events on open, convex features below treeline.

A final pulse of new snow has fallen bringing storm totals to between 30cm (north end of the region) and 90cm (south end of the region). Consistent southerly winds during the storm period has built windslabs in lee terrain. Warm temperatures have consolidated storm slabs on open convex features where the new snow is deepest. Newly buried surfaces include old windslabs, temperature and sun crusts. The new snow is bonding reasonably well at this interface in most locations with the highest concern being the bond to crusts on south and west facing terrain. The January 23rd interface (crusts, facets and surface hoar crystals) lingers in isolated locations. This layer seems to be rounding and bonding under current conditions, but we have reports of a recent size 2.0 releasing on this layer at the north end of the region. The mid pack is generally well settled with the average snowpack depth at treeline around 180 cm.
