Avalanche Forecast

An arctic high persists in the forecast region with no precipitation in the forecast for the next 4 days. An above freezing layer (AFL) is forecast to move into the region Friday with temperatures up to +5c between 1500 and 3000m. Skies should be sunny and clear at upper elevations with valley temperatures below freezing and the possibility of valley fog in the mornings dissipating in the afternoon.

Reports from operators speak of low density size 1's failing on the Nov.23rd surface hoar layer now buried by 10 to 20cm of storm snow

Monday's storm snow fell on a variety of old surfaces including crust, surface hoar and old settled snow. Arctic air moving into the region has resulted in northerly winds forming small wind slabs on south facing features near ridge top and t tree line. Warm temps and strong solar input formed a crust on south facing features which can be found underneath Monday's storm snow. There are at least three surface hoar layers in the snowpack buried on: Nov. 5th, Nov. 11th and Nov. 23rd. The first two have been largely unreactive. Facets may exist just above the ground on shaded slopes in the alpine. Rapid rising temperatures forecast for the next few days may change the snowpack dramatically.
