Regions

Little Yoho.

Another sunny day is expected Friday, with freezing levels reaching 2800 m. Avalanche hazard will start as Low, but the alpine rating reflects the highest expected over the day —start and finish early.

Avalanche Summary

No avalanches besides minor wet loose slides out of steep solar terrain were observed Thursday, and no other avalanches in the past few days. There have been fewer field observations n this area recently.

Snowpack Summary

Hard surface crusts exist to ridgetops in the AM on solar aspects, and at treeline and below on northerly aspects. The top 10-20cm was moistening at the ski hills in the afternoon on Thursday.

On north-facing alpine slopes, 5-15 cm of dry snow over firmer surfaces.

A settled mid-pack sits over the Jan facets down 90 to 150cm, with a well-settled lower snowpack below.

Weather Summary

Friday: The day should start with an overnight freeze, but freezing levels should rise to 2800m in the PM, with light winds and plenty of solar input.

Saturday: There will likely be a weaker freeze in the morning, and freezing levels could possibly go above 3000m in the PM, with light winds and sun.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.

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.
