Sea To Sky

New snow and strong wind will build touchy storm slabs.

Make conservative choices and be very wary of exposure to overhead hazard.

New snow falls on a variety of surfaces, including old wind slab on all aspects, facets, and exposed crust.

The early February crust/facet layer is down 30 to 75 cm.

Another widespread crust and facet layer from late January is buried 40 to 100 cm deep.

The mid and lower snowpack is well settled and strong.

On Thursday and Friday, several skier triggered, remote triggered, and natural size 1 to 1.5 wind slab avalanches were reported in the region. These all occured in alpine terrain.

On Tuesday, several size 1 to 1.5 wind slab avalanches were reported in the region. These avalanches were triggered naturally, by explosives, and by skiers.

Moderate

• We are uncertain about forecast precipitation amounts.
• We are confident the likelihood of avalanches will increase with the forecast weather.
• We are confident a natural avalanche cycle will begin shortly after the arrival of the incoming weather.

• Watch for fresh storm slabs building throughout the day.
• Storm slab size and sensitivity to triggering will likely increase through the day.
• As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
