Avalanche Forecast

Stormy conditions are increasing the likelihood of a natural avalanche cycle. Riders reported touchy storm slab and loose wet avalanches on Sunday, which may also occur during Tuesday's storm.

Stormy conditions continue on Tuesday, bringing periods of strong snowfall that could trigger a natural avalanche cycle. The snow will build over 40 to 60 cm of snow that accumulated since Sunday. All of this snow overlies a hard melt-freeze crust up to at least 1000 m and to ridgetop on sun-exposed slopes and perhaps small surface hoar crystals on shaded slopes sheltered from the wind.

The remainder of the snowpack is well-bonded.

Monday Night

Cloudy with snowfall, accumulation 10 to 15 cm, 30 to 40 km/h southeast wind, treeline temperature -3 °C, freezing level 800 m.
