Avalanche Forecast

Moderate

Small to large (size 1 to 2) storm slab avalanches were triggered by riders, explosives, and naturally over the past couple days. Some of them were triggered by small pieces of cornices failing.

We anticipate similar avalanches will be likely for Tuesday.

More snow is forecast for Tuesday, which will build on the 30 to 40 cm of snow from the weekend. Recent strong to extreme southerly wind made deeper deposits in lee terrain features. All this snow may sit on a weak layer of surface hoar crystals on sheltered and shaded treeline and alpine slopes. The snow overlies a hard melt-freeze crust on sun-exposed slopes and on all aspects below 1500 m.

The remainder of the snowpack is well-bonded.

Monday Night

Cloudy with snowfall, accumulation 2 to 5 cm with local amounts to 10 cm possible, 20 to 40 km/h southeast wind, treeline temperature -7 °C.

Tuesday

Cloudy with snowfall, accumulation 5 to 15 cm, 20 to 40 km/h south wind, treeline temperature -7 °C, freezing level 1000 m.

Cloudy with snowfall, accumulation 5 to 10 cm, 20 km/h south wind, treeline temperature -6 °C, freezing level 1300 m.

Partly cloudy with isolated flurries, 10 km/h southwest wind, treeline temperature -4 °C, freezing level 1500 m.

• Carefully monitor the bond between the new snow and old surface.
• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Be especially cautious as you transition into wind affected terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
