Avalanche Forecast

Check out this MIN for photos of sled triggered avalanches in Allan Creek and this one for a skier triggered avalanche.

Human and naturally triggered avalanche activity continues throughout the region with avalanches ranging in size from 1.5 to 3.5. Some avalanches have  run full path to valley bottom. Many human triggered avalanches have been remotely triggered and also resulted in sympathetics.

We expect this type of avalanche activity to continue.

The wind has come from a variety of directions, wind effect could be found on all exposed terrain at higher elevations. A new crust or moist snow will be found on south and west facing slopes.

40 to 80 cm overlies a layer of surface hoar in wind-sheltered terrain, weak facets, or a hard melt-freeze crust on south and west-facing slopes.

A thick and hard widespread crust that formed in early February is buried about 60 to 120 cm deep. This crust may have a layer of facets above it. The snowpack below this crust is generally not concerning except in shallow alpine terrain.

Monday Night

Mostly clear skies with trace amounts of new snow. 15 to 35 km/h southwest alpine wind. Treeline temperature  -15°C.

Tuesday

A mix of sun and cloud. 15 to 35 km/h southwest alpine wind. Treeline temperature -13°C.

Wednesday

Sunny. 5 to 20 km/h southwest alpine wind. Treeline temperature -11°C.

Thursday

A mix of sun and cloud. 15 to 35 km/h south alpine wind. Treeline temperature -7°C.

• Conservative terrain selection is critical, choose only well supported, low consequence lines.
• Remote triggering is a concern, watch out for adjacent and overhead slopes.
• Be aware of the potential for surprisingly large avalanches due to deeply buried weak layers.
• If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Avoid exposure to steep sun exposed slopes.
