Avalanche Forecast

Friday Night: Clear skies, moderate wind from the northeast, alpine temperatures -12 C.

Saturday: Mix of sun and cloud, light wind switching to SE, alpine high -8 C.

Sunday: Increasing cloud in the afternoon, moderate wind from the southwest, alpine high -8 C.

Monday: Cloudy with isolated flurries, wind increasing to strong from the southwest, alpine high -5 C. Freezing level 700 m.

Ridge tops and slopes where previous wind has deposited blowing snow are places where avalanches could most likely be triggered right now. Early season avalanches can most easily propagate and run in areas where the underlying ground is smooth, such as on glaciers, rock slabs, scree, or grassy slopes.

Observations are limited this time of year, so there is a fair bit of uncertainty about the extent of current avalanche activity. If you see anything while out in the field, please consider sharing that information with us and fellow recreationists via the Mountain Information Network (MIN).

Recent reports describe scoured windward aspects, hard wind slabs and variable snow depths due to wind transport in the alpine and treeline. Up to 50 cm overlies the rain crust at these elevations. Soft snow may still be found below treeline but the snow pack is quite thin at this elevation. Underneath the surface snow at higher elevations lies a lower snow pack largely characterized by sandwiches of crusts and large, weak snow crystals (facets), as observed in another recent MIN report. We're also keeping an eye on a potential surface hoar layer (see video here). With few field observations, uncertainty remains on the distribution and reactivity of these layers.
