1 size 2 and numerous size 1 explosives-controlled avalanches were observed in the Whistler area on Monday.

The region saw variable amounts of snow with moderate to strong winds and warmer temperatures on Sunday. The variable and cohesive windslabs that formed at treeline and in the alpine have strengthened somewhat, but could become reactive on unsupported features below ridgecrests. These new windslabs are resting on impressive amount of storm snow that fell last week. By now last week's storm snow should be well settled.About a metre down there are a variety of older snow surfaces that formed throughout January. These surfaces include facets, old wind slabs, and crusts. These interfaces have also gained considerable strength, but triggering may be possible with a heavy load in isolated terrain. Previous concerns about deeper persistent weak layers appear to have diminished.Snowpack depths at treeline are in the region of 260 cm.
