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.

Confidence

Moderate

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

Avalanche Summary

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

Snowpack Summary

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.

Terrain and Travel Advice

  • 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.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
