Avalanche Forecast

Several storm slab and wind slab avalanches up to size 2 were reported on Monday and Tuesday, both natural and rider-triggered. While recent explosive control work has produced a few storm slab avalanches up to size 3.

Moderate to strong north to east winds continue to redistribute recent snow into wind slabs in exposed terrain on all aspects.

Down roughly 30 to 60 cm from the surface are a layer of surface hoar in wind-sheltered terrain and a sun crust on steep south-facing slopes.

A slightly older layer of large surface hoar may be found down roughly 50-80 cm below the surface. Otherwise, the snowpack is generally well consolidated and bonding.

The lower snowpack consists of a layer of weak, sugary crystals that is slowly gaining strength and doesn't currently appear to present the same problem as neighboring regions to the north and east. However, we continue to track the layer and watch for any signs that it could wake up and produce very large avalanches.

Thursday night

Mostly clear / Moderate northeast ridgetop winds / Treeline temperatures around -20 C.

Friday

Sunny / Light northerly ridgetop winds, shifting to the southwest by end of the day / Treeline temperatures -15 to -20 C.

Saturday

A mix of sun and clouds, snow beginning at end of the day / Light to moderate southwest ridgetop winds / Treeline temperatures -10 to -15 C.

Sunday

Snowfall, 10 to 20 cm / Moderate southwest ridgetop winds / Treeline temperatures -5 to -10 C.

• Be especially cautious as you transition into wind affected terrain.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
• Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.
