Continuously assess conditions as you move through terrain.

Where the snow surface is dry small wind slabs may exist , where it’s wet loose avalanches are possible.

Moderate

• Uncertainty is due to rapidly fluctuating freezing levels.
• Uncertainty is due to limitations in the field data.

No new avalanches were reported in the region on Monday.

Several human triggered avalanches size 1 to 1.5 were reported on Sunday off the Coquihalla in the Zoa area. A larger size 2 wind slab was also reported. This avalanche was human triggered on a cross loaded feature at treeline.

Dry, wind affected snow can still be found in the alpine on north aspects. Early in the morning a new surface crust could be found on south aspects at treeline but it’s expected to break down quickly.

The Mid December crust is found down 50 to 150 cm. In general the snowpack is right-side up and well settled.
