A report from Monday indicates a size 2.5 explosives controlled cornice failure stepping down to what was suspected to be a mid-February persistent weak layer in the Duffy Lake area. Another report from the same area indicates a size 3 large explosives triggered avalanche stepping down to what was suspected to be a November persistent weak layer. There was also a social media report from Sunday that describes two skier triggered wind slab avalanches in the Heart Strings area. Click here for details and photos. There have been no new avalanche reports from the Coquihalla area or south of the region in the past several days.On Wednesday, recently formed wind slabs are expected to remain reactive to human triggering. These slabs are expected to be particularly touchy where they overlie a melt-freeze crust.

5-15cm of new snow falling at upper elevations Tuesday night into Wednesday is sitting on a widespread melt-freeze crust on all aspects and elevations except for high elevation north facing terrain. Recent strong winds from the south have formed new wind slabs in the alpine and have added load to cornices. On sun exposed slopes and at lower elevations, several crusts likely exist in the upper snowpack which are generally well bonded.
