Avalanche Forecast

Moderate

On Sunday, numerous natural, size 1, wet loose avalanches were observed below treeline.

With forecasted new snow and wind, storm slabs will likely be reactive on Tuesday.

If you are headed to the backcountry, please consider sharing your photos and observations from your day on the Mountain Information Network.

20 to 40 cm of new snow is expected by Tuesday afternoon, forming touchy storm slabs. This could bring storm snow totals in the alpine near 100 cm since the weekend. High north-facing slopes may see deeper deposits of wind-transported snow.

At treeline and below, the new snow will sit above a crust on all aspects. This crust has approximately 30 cm of dense, saturated storm snow below, with the upper snowpack generally seeing moist throughout.

The mid and lower snowpack contain several crusts that are not concerning.
