Sea To Sky

Be cautious in alpine and ridgeline features of lingering wind slabs.

Continue to assess conditions as you transition into wind-affected terrain.

Moderate

• We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

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.

Over the previous 3 days several, small  wind slab and dry loose avalanches have been observed in the region. These avalanches were triggered naturally and by skiers in steep terrain.

10 to 25 cm of recent snow with moderate to strong southerly wind has buried a variety of surfaces including a layer of surface hoar in sheltered treeline features and a sun crust on east through west aspects. The surface is expected to become moist on sun exposed slopes during the day.

The early February crust/facet layer is down 30 to 60 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.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
• Recent strong wind means wind slabs may be found farther downslope than expected.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
