The wind has switched from mostly southerly to northerly, so expect to see windslabs on a variety of aspects.
Recent new snow combined with moderate to strong winds from a variety of directions have promoted new wind slab formation on a variety of aspects.
Two weak layers consisting of a crust with small facets above buried between 50 and 180cm deep, have been responsible for several large avalanches in the past two weeks. This problem seems to be more of an issue west of the Sea to Sky highway corridor.
Most recent avalanche activity has been reported as size 1-1.5 wind slabs in the alpine.
There was a report of a natural size 3 persistent slab avalanche in the Brandywine area last Saturday evening. This was on a northeast aspect at 1750m. More details can be found here.
Recent new snow is being redistributed by moderate to strong winds blowing primarily from the southwest then switching to north and northeast.
A crust that formed in late January with small facets above it, can be found at all elevations down 40-100 cm. This crust has been reactive to rider traffic in the Rhododendron and Pemberton Icefield area. Additionally, a crust with facets above, found 80-200 cm deep and 1900m and below in elevation has recently been reactive in the Brandywine area.
