Avalanche Forecast

Fair - Timing, track, or intensity of incoming weather is uncertain on Monday

Overnight Saturday: Another 5-10cm should bring storm snow amounts to 20-30cm.Sunday: Flurries. Cold temperatures, with the freezing level near valley floor. Northerly winds.Monday/Tuesday: Two main influences will battle for control of the region's weather: cold arctic air and a low pressure centre near Vancouver Island with an associated westerly flow. Expect some flurries, cold temperatures and the chance of strong outflow (northerly or easterly) winds if the arctic air dominates.

No new avalanches have been reported, but I'd expect some sluffing of the dry new snow in steep terrain and possibly wind slab avalanches near ridge top to be occurring today.

20-40cm of dry new snow has landed on a hard supportive crust in the Coquihalla area and dry facets in the Duffey Lake area. Initial reports from the Coquihalla area on Saturday indicated that the snow is bonding well to the crust. At ridgetop, south-westerly winds are likely to be creating wind slabs which may fail on the dry storm snow and/or the icy crust. Deeper in the snowpack, two persistent weak layers remain a concern only in thin snowpack areas (perhaps wind-scoured zones or relatively dry eastern ranges) and particularly in steep rocky terrain or sheltered, low-snowpack terrain. The two layers are surface hoar and/or facets associated with a crust from mid-December and/or sugary facets at the base of the snowpack.
