If the sun comes out, wet loose will quickly become a problem.

Avoid being underneath slopes or cornices that are in the sun.

Confidence

Avalanche Summary

On Thursday, numerous small wet loose avalanches were reported. Both natural and rider-triggered.

Near Fernie, several large (size 2) storm slabs were triggered with explosives.

Snowpack Summary

A new surface crust has likely formed on slopes that face the sun. Around 10 to 20 cm of new snow fell on Thursday, which sits on a thin melt-freeze crust.

A thick crust is buried 30 to 40 cm deep, which makes it unlikely to trigger any weak layers that persist below it in the upper snowpack.

The mid and lower snowpack is strong in most areas. Snowpack depth tapers rapidly at lower elevations.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Make observations and continually assess conditions as you travel.

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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
