Winds have varied throughout this region, with recent avalanches on north and south facing slopes.

Stick to conservative terrain - human triggering of large avalanches is likely

Moderate

• We are uncertain due to how buried persistent weak layers will react with the forecast weather.
• We are uncertain due to the variability of wind effect on the snowpack.

Wind slabs up to size 2.5 continue to be observed, likely occurring throughout rapid wind transport. These have occurred in north and south facing terrain features, indicating variability in wind patterns.

Please post any photos or observations to the MIN if you head out.

Up to 30 cm of recent snow has been redistributed into deeper deposits on north and east facing slopes. Windward slopes may be scoured back to an old crust.

Two notable layers exist in the snowpack. A layer of facets from early February, up to 40 cm deep. A thick crust from late January, 50-100 cm deep. Both of these layers are a concern in wind affected terrain.

The remainder of the snowpack is well settled.

Sunday Night
Partly cloudy. 1 to 2 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -3 °C.

Monday
Mostly cloudy. 1 to 4 cm of snow. 60 km/h west ridgetop wind. Treeline temperature -2 °C.

Tuesday
Mostly cloudy. 4 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Wednesday
Mix of sun and clouds. 2 to 3 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Recent wind has varied in direction, so watch for wind slabs on all aspects.
• Be aware of the potential for large avalanches due to buried weak layers.
