Freezing levels on Thursday are uncertain. As a result, forecast precipitation may come in as a combination of rain (low elevation), snow (high alpine) and/or freezing rain (between 1000-1300m).

Recent avalanche activity has been reported as small loose dry avalanches in steep terrain on all aspects along with isolated wind slab avalanches on east aspects in the alpine and at tree line.

Up to 10cm of new snow has fallen in some parts of the region so far in the new year. Cold temperatures and strong winds (from a wide range of directions) have affected the surface snow over the past week, scouring some slopes down to an old crust and forming hard deposits in many other areas. There are some lingering wind slabs, found on a variety of old surfaces including a thick melt-freeze crust that formed in mid-December. Cornices have also been noted at ridge tops, lee (downwind) to strong north east winds last week. In non-wind affected terrain, 20-40 cm of faceted (sugary) snow overlies the mid-December crust layer. This snow has been sluffing in steep terrain.Beneath the mid-December crust the snowpack is reported to be generally strong with the possible exception of areas around Stewart and northern parts of the region where the late-October, basal crust can be found near the base of the snowpack. Weak sugary faceted snow may exist around this deeply buried crust and could be triggered from shallow snowpack areas.
