Regions: Cariboos.

Storm slabs may be reactive to human triggering, especially in wind loaded areas at upper elevations. Watch for signs of instability such as whumphing, cracking and recent avalanches.

Weather Forecast

SATURDAY NIGHT - Cloudy with clear periods and isolated flurries / southwest winds, 35-60 km/h / alpine low temperature near -8SUNDAY - Mainly cloudy with scattered flurries, up to 5 cm / south winds, 20-40 km/h / alpine high temperature near -5 / freezing level 1700 mMONDAY - A mix of sun and cloud / southeast winds, 10-20 km/h / alpine high temperature near -4 / freezing level 1800 mTUESDAY - Cloudy with sunny periods / north winds, 10-20 km/h / alpine high temperature near -2 / freezing level 1900 m

Avalanche Summary

On Thursday, there were reports of a few human triggered size 1 loose wet avalanches at treeline within the new snow.There has been three cornice failures observed in the region since Monday. One triggered a large avalanche that scrubbed down to the base of the snowpack, one triggered a thin slab avalanche and one did not trigger a slab.

Snowpack Summary

15-25 cm of new snow in the alpine and at treeline sits on a melt-freeze crust on all aspects except for north slopes above 1800 m, where it sits on dry snow. Snow is disappearing rapidly at lower elevations.

Avalanche Problems

Wind Slabs

Up to 25 cm of recent storm snow sits on a crust in most locations, and on dry snow on north facing alpine terrain. Strong southwest winds will have formed wind slabs at upper elevations.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
