Avalanche Forecast

High

There were a few skier-triggered size 1 wind slab and dry loose avalanches reported from steep terrain on Tuesday. This MIN post is a great example of where the wind slab can still be triggered by riders.

Brief periods of sun, triggered natural and skier-controlled wet loose up to size 1.5 on Tuesday.

Roughly 20 to 30 cm of recent snow has been incrementally building over a crust at treeline and alpine elevations. Lower elevation surface snow is likely moist or wet depending on recent freezing levels.

A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets sitting on a crust is buried 80-100 cm deep. While previous warming and subsequent cooling have likely helped to strengthen these layers, we will continue to monitor them for signs of reactivity.

Wednesday Night

Mainly cloudy with 2 to 3 cm accumulation. Alpine wind northwest 5 to 10 km/h. Treeline temperature -5 °C.

• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
