Avalanche Forecast

Sporadic reports continue to provide evidence that buried surface hoar layers remain human-triggerable. Avalanches up to size 2.5 have mostly occurred in treeline and alpine terrain, but have been reported as low as 1950 m.

This Mountain Information Network (MIN) post from neighboring Glacier National Park is the most recent occurrence.

Roughly 30 cm of recent snow continues to settle and stabilize with mild temperatures and minimal wind. A layer of buried surface hoar may exist below the recent storm snow in wind-sheltered features. A crust exists down roughly 40 cm from the surface at treeline and below.

A problematic layer of surface hoar is now roughly 50-90 cm below the surface.

The lower snowpack is generally facetted with a hard crust found just above the ground. Generally, the snowpack remains shallow for this time of year, with average treeline snow depths around 80 to 120 cm.

Tuesday Night

Cloudy with 2 to 8 cm of snow, southwest alpine winds 20 to 40 km/h, treeline temperature -2 °C.

Wednesday

Cloudy with 2 to 8 cm of snow, southwest alpine winds 20 to 40 km/h, treeline temperature -2 °C.

Thursday

Cloudy with 2 to 8 cm of snow, southwest alpine winds 40 to 60 km/h, treeline temperature -2 °C.

Friday

Cloudy with 2 to 8 cm of snow, south alpine winds 40 to 60 km/h, treeline temperature -2 °C.

• Uncertainty is best managed through conservative terrain choices at this time.
• Avoid areas where the snow feels stiff and/or slabby.
• Use caution when approaching steep and rocky terrian.
