Weather Forecast

The general weather pattern is forecast to continue: warm days & cold nights, little to no precipitation, little significant wind. The exception to this may be Thursday with a small disturbance moving through bringing some cloud and a dusting of snow.

Avalanche Summary

Surface snow has been sluffing readily with rider traffic on steep shady slopes (northerly facing) and strong solar radiation has resulted in afternoon snowballing and isolated small wet loose avalanches. Deep persistent slab avalanches remain possible with heavy triggers (like cornices) in shallow rocky snowpack areas on unsupported slopes.

Snowpack Summary

5-15cm of fresh snow is sitting on the major surface hoar created at the beginning of the month. This interface will be one to watch as it receives more snow load and/or the slab settles. Below that 30cm of near-surface facets can be found on shady slopes while a sun crust can be found on southerly aspects. Moist snow reported to near treeeline. In shallow snowpack areas concerns remain for the mid-December persistent weakness down around 80-100cm and for basal facets.

Problems

Deep Persistent Slabs
