Sea To Sky

Cornice and wet loose avalanches are possible in steep terrain.

Use caution on sun-exposed slopes and always practice good travel habits.

Observations since the weekend have been limited to explosive-triggered cornices (size 2 to 2.5) and small wet loose avalanches.

Following last week's widespread avalanche cycle, there were still some notable events over the weekend, including a size 2.5 slab triggered by a cornice fall on Tremor Mountain (see photo). The persistent slab problem is currently dormant and likely requires a very large cornice fall on isolated slopes to trigger.

Expect wet and moist surfaces on sun-exposed slopes. 10 to 20 cm of wind-affected dry snow exists at high elevations, sitting over a melt-freeze crust. Below this, the upper snowpack remains moist or wet.

Several persistent weak layers from January, February, and March can be found between 1 and 3 m deep in the Sea to Sky area.

At lower elevations, the rain-saturated snowpack tapers quickly with elevation.

• Be alert to conditions that change with elevation, aspect, and exposure to wind.
• Carefully evaluate big and steep terrain features before committing to them.
• Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
