Snowpack Summary
The south of the region has seen impressive storm snow totals (50-70cm) since Sunday night, compared to the north of the region, which received 15-25cm. This new snow sits on crusts of variable thickness that formed on almost all aspects in early December. On steep southerly aspects the crust is supportive, whereas on northerly aspects the crust is quite thin and variable. Moderate to strong (north) westerly winds have redistributed the new snow, creating deep drifts on down wind (lee) features. Lower down, the snowpack is well settled and has not been showing any signs of activity on the late November rain crust.Treeline snow depths are approximately 1.4 m throughout the region.
