Alpine: LOW, watch for daytime warming
Treeline: LOW
Below Treeline: LOW
Travel Advisory: A variable and increasingly dense sandwich of weak crusts and soft to hard slabs are sitting on the April 9 crust. Daytime heating will continue to soften and settle these layers, while overnight cooling will rebuild the surface crust. Any direct solar exposure is likely to result in loose wet avalanche activity.
Avalanche Activity: Any sunny breaks will cause moistening on solar aspects and sluffing is likely to occur from steep start zones.
Snowpack: The April 9 melt freeze crust is sitting about 50 cm below the surface. Above this crust the snowpack is variable – north aspects in the alpine remain somewhat winter like, while solar aspects are harbouring an assortment of weak crusts within the storm snow. The bond between the storm snow and the latest melt freeze crust is good and shears above the crust have tightened in.
Weather: Clouds and flurries are expected to be with us for the remainder of the week. Temperatures are forecast to gradually moderate toward the weekend.
