Avalanche Summary

Small wet and dry loose avalanches continue to be triggered by skiers in steep terrain.

Snowpack Summary

During the day on Friday the snow surface will become moist on all aspects and elevations except for high north facing terrain, where up to 30 cm overlies a crust from late March. Below these crusts, the upper snowpack is moist.

Several weak layers from early March, mid February and late January can be found in the mid and lower snowpack.

The remainder of the snowpack is generally well settled.

Terrain and Travel Advice

Back off slopes as the surface becomes moist or wet with rising temperatures.
Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Make observations and continually assess conditions as you travel.
Avoid travelling on slopes below cornices.

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.
