Avalanche Summary
Several skier triggered and some natural windslab avalanches have been reported since Friday. Several loose dry avalanches have been reported in steep terrain since Thursday. Windslabs will continue to be reactive to rider triggers.
Snowpack Summary
In some areas, there's a thin crust over 30 to 50 cm of soft snow. Below that, in sheltered spots, you might find surface hoar (feathery crystals). On south-facing slopes, a crust can be found under the soft snow. Windslabs are present in exposed areas at alpine and treeline elevations.
The surface hoar on the crust/facet layer, found 90 to 160 cm down, is hard to find and likely not a concern north of Highway 5. South of Highway 5 it may linger on north through east aspects between 1700 to 2300 m.
Snow depth at treeline is between 120 and 250 cm.

Terrain and Travel Advice
- Wind slabs are most reactive during their formation.
- Stay off recently wind loaded slopes until they have had a chance to stabilize.
- Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.
