Regions

Jordan, Shuswap, Gold, North Okanagan, Whatshan.

Keep an eye on changing conditions and dial back your objectives.

We are confident that warming and solar will trigger avalanches, but we are uncertain in the that will occur.

Confidence

Moderate

  • We are confident that there are weak cornices, but uncertain about how likely they are to trigger.
  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

Over the past 4 days several small wet and dry loose avalanches in steep or extreme terrain were observed.

Observations are limited in this region this time of year.

Snowpack Summary

Surface conditions are highly variable:

·        In exposed alpine and treeline terrain recent variable wind has scoured ridge tops and formed small wind slabs in lee features.

·        Sheltered treeline features may hold dry snow.

·         Below treeline A firm crust is on or just below the surface on all aspects.

·        A crust exists on or near the surface on sun exposed slopes. This crust will break down with solar input and rising freezing level.

The melt freeze crust from the atmospheric river event is buried up to 50 cm. The snowpack below this crust is well consolidated.

Weather Summary

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Avoid travelling on slopes below cornices.
  • Be careful as you transition into wind-affected terrain.

Problems

Wet Slabs

Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive.

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.
