Avalanche Forecast

Poor - Due to the number of field observations

An Arctic high pressure system dominates the forecast for the next few days.  Clear, cold, and dry conditions are expected until at least Thursday.Sunday: Sunny, treeline temperature around -30, light-moderate NW alpine wind Monday: A mix of sun and cloud, treeline temperature around -25, light W alpine wind Tuesday: Mostly sunny, treeline temperature around -20, moderate-strong NW alpine wind

We haven't had any new reports since last weekend. If you have any observations, please send them to forecaster@avalanche.ca. Recent observations from the Rogers Pass area where the conditions are expected to be similar include widespread natural activity up to size 3.5 on Thursday and Friday. A natural size 3 was also reported on Saturday.

The storm produced a slab up to 1 m thick which sits on the mid-November weak layer (facets, surface hoar, and/or a sun crust on steep southerly slopes). 20-30cm below this layer is a thick rain crust with weak facets on top. Snowpack data from the Cariboo region is very limited at the moment but I expect these layers are reacting similarly to the North Selkirk/Monashees because the formation conditions were generally the same.  Recent strong and variable winds have probably created dense wind slabs in exposed terrain and resulted in variable snow distribution in the alpine.
