Sea To Sky

Any surface crust that forms overnight will break down quickly. Start and finish your day early.

Wet loose avalanches are possible on steep slopes when the snow surface is wet.

• We have a good understanding of the snowpack structure and confidence in the weather forecast.

Over the past few days numerous wet loose avalanches up to size 2 were reported. These avalanches occurred predominantly on solar aspects.

A thin crust may exist early in the morning on most terrain but it will break down quickly. The snow below is likely moist or wet. The exception to this is high north facing terrain where dry snow could still exist.

A thick crust, with facets above it, can be found down 10 to 50 cm at treeline and above. Previous wind may have scoured exposed features back to this crust.

The mid and lower snowpack is well settled and strong. At low elevations the snowpack is disappearing quickly.

• Loose avalanches may start small, but they can grow and push you into dangerous terrain.
• Back off slopes as the surface becomes moist or wet with rising temperatures.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
