Avalanche Forecast

High

No new avalanches have been reported.

A small (size 1) slab avalanche was reported near White Pass last weekend.

Cornice falls were observed to have triggered large avalanches last weekend and are expected to remain weak.

A skiff of new snow may overlie a widespread crust that exists up to roughly 1300 m. Daytime warming may soften this crust at low elevations.

At higher elevations, the snow is likely to be wind-affected. Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.

Soft dry snow may still be found on north-facing alpine slopes.

In some areas, particularly in the Haines Summit, a weak layer of facets or surface hoar is buried 50-80 cm. This layer is unlikely to trigger from the weight of a rider, but concern exists with very large loads like cornice falls.

• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
