Avalanche Forecast

Poor - Due to limited field observations

Monday:  Freezing Level: 500m Wind: Mod S/SW, No significant precip.Tuesday: Freezing Level: 500m rising to 750m, Wind: Light W, No significant precip.Wednesday: Freezing Level: 500m Wind: SW, initially moderate increasing to strong by sundown.  10cm of snow expected.

No recent avalanche observations have been reported.

Depending on the location, light to moderate amounts of new snow have been shifted into wind slabs and overlie older wind slabs that formed earlier in the week. Below treeline, light rain and warm temps have saturated the surface which has left a crust below around 1000m. In general, between 30-60cm of storm snow sits over a variety of old surfaces which include facets, crusts and isolated pockets of surface hoar (sheltered treeline and below treeline). There is very limited information about the nature of this interface, with the only results suggesting reactivity in sheltered, shady treeline and below treeline slopes (preserved surface hoar). I would stress the importance of digging down to find and test weak layers.A strong mid-pack currently overlies a weak base layer of facets/depth hoar. It is worth noting that the snowpack in general is quite shallow compared to averages; triggering the basal weakness may still be possible from thin spots, rocky outcrops or under the weight of larger triggers such as cornice fall.
