Avoid areas where the wind has created deep deposits.

The new snow could be sitting on a touchy layer of surface hoar.

Summary

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported since the 25th of Nov.

Snowpack Summary

5 to 10 cm of new snow or wind loading may hide large surface hoar crystals in sheltered areas. This could be shallow, but easy to trigger.

Thin melt-freeze crusts may be found on sun-exposed slopes under the 5 cm of new snow.

The most prominent of several melt-freeze crusts in the lower snowpack is 100 - 150 cm deep in the Whistler area and decomposing.

Snowpack depth is around 130 cm at treeline and decreases rapidly below about 1500 m.
