Avalanche Forecast

High

A natural avalanche cycle is expected to occur throughout the day on Saturday with the incoming intense snow and wind.

Observations are limited at this time of year, please consider sharing any information or photos you have on the Mountain Information Network to help guide our forecasts.

Forecast intense snow and wind are expected to form large and reactive storm slabs on Saturday.

Below the new snow, a melt-freeze crust likely exists on all aspects below 1400 m.

The middle and lower snowpack are strong and well-bonded.

At lower elevations, the snowpack was recently rain soaked.

Friday Night

Snow; 5-20 cm (rain below 800 m) / 60 km/h south ridgetop wind / Temperature at treeline around 0 C / Freezing level 1100 m

Saturday

Snow; 15-35 cm (rain below 900 m), then another 20-40 cm overnight / 50 km/h south ridgetop wind / Temperature at treeline around 2 C / Freezing level 1200 m

Sunday

Mix of sun and cloud with flurries; 5-15 cm / 40 km/h southwest ridgetop wind / Temperature at treeline around -1 C / Freezing level 1000 m

• Avoid all avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Avoid exposure to overhead avalanche terrain, avalanches may run surprisingly far.
• Storm slab size and sensitivity to triggering will likely increase through the day.
