Avalanche Summary
We continue to receive observations of isolated small soft slabs in the alpine that are sensitive to skier triggering.
Snowpack Summary
Relatively small pockets of wind slab which exist at higher elevations are expected to be mostly unreactive. but may be triggered by skiers in isolated pieces of terrain near ridge crest. In shaded areas at treeline and below the new snow may overlie surface hoar which is reported to be reactive in the Meager Group (upper Lillooet). Several crusts can be found in the snowpack, especially on solar aspects; however, reports indicate these interfaces have settled out fairly rapidly in most areas. The mid and lower snowpack layers are generally strong and well settled.Total snow depths vary from around 400 cm in the south to around 180 cm in the north.
