Avalanche Forecast

Moderate

Thursday The field team reported a size 1 (small) wind slab avalanche in the Ground Hog area by Barkerville out of steep north-facing alpine terrain. Check out this MIN for more details.

Wednesday A few size 1 (small) skier-triggered slabs were reported in the Cariboos near Quesnel Lake. They were 55 cm deep and failed on a weak layer of surface hoar.

Tuesday A natural size 2.5 (large) wind slab was reported on a southwest face at treeline north of Powder King.

Previous strong winds have created wind slabs in exposed areas at treeline and above on south and westerly faces.

10-20 cm of new snow fell in the region earlier this week, adding to about 20-30 cm of older storm snow. Collectively, this snow sits on a crust up to 1400 m in the north and 1900 m in the south. In parts of the Cariboos, this snow may also overlie a weak layer of surface hoar.

Two more layers of surface hoar may be found buried between 90 and 150 cm at treeline. The likelihood of triggering these layers is low, with the possible exception being shallow, rocky areas at upper treeline.

The current snowpack has considerable variation in structure and depths across the region and is shallow for this time of year.

Friday night

Mostly clear with no new snow, northwesterly wind 20-30 km/h, treeline temperature low of -37°C

Saturday

Partly cloudy with no new snow, southwest wind 15-20 km/h. treeline temperature high of -24°C.

Sunday

Mix of sun and cloud with no new snow, northwest wind 20-30 km/h, treeline temperature high -21°C.

Monday

Cloudy with no new snow, northwest wind 30-50 km/h, treeline temperature high -15°C.

• Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
• The best and safest riding will be on slopes that have soft snow without any slab properties.
