Avalanche danger will increase as an intense storm, with lots of wind and snow, moves through.
Avoid avalanche terrain while the storm snow settles.

• Avoid avalanche terrain during periods of heavy snowfall.
• Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
• Avoid lee and cross-loaded slopes in the alpine.

Numerous small, wet loose avalanches were reported on Monday and Tuesday.

Around 10 cm of snow sits over a widespread melt–freeze crust that extends to approximately 2400 m in the alpine. Beneath this crust, the snow remains moist due to the recent warm and wet weather. Lower elevations are rain soaked and likely have a surface crust, where there is snow.

The mid-snowpack is generally well-settled and well-bonded, sitting above a thick melt-freeze crust that makes up most of the lower snowpack.

Snowpack depths at treeline range from 80 to 150 cm and thin rapidly at lower elevations.
