Avalanche Forecast

Moderate

No avalanches have been reported in the past few days. Please consider filling out a MIN report if you are out in the backcountry.

Surface conditions are highly variable. In the alpine steep south facing terrain has a sun crust and all other aspects are wind effected. At treeline a crust can likely be found on all aspects, on sheltered features large surface hoar could exist. This surface hoar will be something to keep in mind after it is buried. Below treeline the snowpack tapers off quickly.

A crust buried on November 21 is down 10 to 30 cm.

Above about 1600 m, snowpack height ranges from 50 to 100 cm, increasing with elevation and deepest on the west side of Hwy 99. The base of the snowpack is well consolidated and bonded to the ground and glacial ice.

Monday Night

Mostly clear with no new snow expected, southwest  alpine wind 10 to 25 km/h, treeline temperature around -4°C, possible temperature inversion with alpine temperature around -1°C.

Tuesday

Sunny in the morning with increasing cloud in the afternoon, no new snow expected, southwest alpine wind 10 to 25 km/h, above freezing layer around 2000 m.

Wednesday

Mostly clear, no new snow expected, southeast alpine wind 5 to 15 km/h, treeline temperature around -5°C.

Thursday

Cloudy with trace amounts of new snow expected, southwest alpine wind 15 to 25 km/h, treeline temperature -5°C.

• Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
