Many small storm slab avalanches were triggered on Sunday within the recent storm snow. A similar trend likely occurred as the storm continued on Monday.

We'd appreciate any observations while you are out travelling on the Mountain Information Network.

A substantial amount of snow has accumulated in the region since January 1, with storm totals over 100 cm for much of the region. More snow is forecast into Tuesday. All this snow has formed a touchy storm slab in sheltered areas and wind slabs in exposed terrain at higher elevations.

The storm snow overlies a weak layer formed during the cold spell in late December. The weak layer consists of sugary faceted grains as well as potentially feathery surface hoar found in areas sheltered from the wind. In high-elevation terrain exposed to the wind, the snow likely overlies a hard wind-affected surface.

The middle and base of the snowpack are strong, consisting of well-bonded snow and a few hard melt-freeze crusts.

• Travel in alpine terrain is not recommended.
• Use increased caution at all elevations. Storm snow is forming touchy slabs.
• Avoid all avalanche terrain during periods of heavy loading from new snow and wind.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Stick to simple terrain and be aware of what is above you at all times.
• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
