Avalanche Forecast

Moderate

Last week there were continued reports of large natural and explosive controlled avalanches to size 3 in the alpine and treeline. These reports have started to tapper off and there have been no new avalanches reported this weekend.

Keep in mind as natural activity tapers off rider triggered avalanches remain possible.

Roughly 50-80 cm of soft snow is on the surface in sheltered areas and is wind affected in the alpine and open treeline. This snow overlies a variety of old surfaces, but sheltered terrain where it may overlie preserved surface hoar, is the most concerning. Below 1600m a crust is present beneath the storm snow.

Two additional surface hoar layers in the top 2 m of the snowpack are diminishing in importance. The deeper of the two likely has a robust crust above it, below treeline. The depth of the snowpack varies greatly throughout the region and weak basal facets are present at the base of the snowpack.

Sunday Night

Clear with no new snow, north alpine wind 10-40 km/h, treeline temperature -30 °C.

Monday

Mostly sunny, variable alpine wind 10-50 km/h, treeline temperature -23 °C.

Tuesday

Mostly cloudy with 5-10 cm of snow, variable alpine wind 10-30 km/h, treeline temperature -20 °C.

Wednesday

Mostly cloudy with 5-10 cm of snow, southeast alpine wind 10-40 km/h, treeline temperature -16 °C.

• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
• Overhead hazard may not be obvious, evaluate prior to commiting to terrain.
