South Coast Inland

Avalanches are possible in wind-loaded areas at treeline and above. Winds have changed directions and built wind slabs on all aspects. Carefully evaluate wind loading as you move through terrain and investigate the bond of wind slabs to the crust below them before committing to a slope.

On Monday afternoon, search and rescue technicians responded to a fatal avalanche incident north of the Sea to Sky region. The avalanche is believed to have occurred on Saturday and was initiated in a shallow rocky area. See the MIN for more details.

A skier remote triggered, size 2 avalanche was reported on a cross-loaded morainal feature. The group reported the avalanche as a soft wind slab over a crust. The slope fractured 30 m above the group. See the MIN for more information.

A few small skier accidental storm slabs were reported, up to size 1. A few size 1 loose dry avalanches were observed in steep rocky terrain.

Please continue to share any observations or photos on the Mountain Information Network.

10-20 cm of recent storm snow overlies wind-affected surfaces at higher elevations and a crust at lower elevations. On solar steep slopes, a new sun crust has formed on the surface.

A melt-freeze crust from late January is found down 60-80 cm. At the moment this layer appears to be gaining strength though in isolated areas small facets are still found surrounding the crust.

The snowpack in this region is generally weak and shallow with sugary snow near the base. Avoid areas where snowpack depth varies rapidly like thin rocky start zones. Snowpack depths around treeline range between 150 to 250 cm.

• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Approach lee and cross-loaded slopes with caution.
• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
