Regions

Clearwater, South Okanagan, Shuswap, North Okanagan.

Until cold temperatures lock in this warm and wet snowpack, dangerous avalanche conditions and poor riding quality will exist.

Confidence

Moderate

Avalanche Summary

Several wet loose and wet slabs up to size 2 have been reported in the region. These avalanches were reported from 2000 m.

Snowpack Summary

Wet snow exists in the upper snowpack to mountain top.

A layer of facets formed during the mid January cold snap sits 30-50 cm deep. Another weak layer consisting of a crust and facets is down 50 to 100 cm.

Weather Summary

Tuesday Night

Partly cloudy with light rain expected, south alpine wind 20km/h, freezing level around 2000 m.

Wednesday

Mostly cloudy with light rain/snow expected, southwest alpine wind 15 to 20 km/h, freezing level around 2000 m.

Thursday

Cloudy with light rain/rain possible, southeast alpine wind km/h, freezing level rising to 1900 m.

Friday

Mostly cloudy, southeast alpine wind 10 to 20 km/h, freezing level rising to 1900 m.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Keep in mind that wet avalanches can be destructive due to their high density.

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.
