Flurries and recent snow continues to be redistributed by wind. Wind slabs will be most reactive around ridges and in leeward terrain.
Triggering wind slab avalanches is possible around ridge features and other steep alpine terrain.

THURSDAY NIGHT: Cloudy with isolated flurries bringing 5-10 cm of snow, 30-50 km/h wind from the southwest, alpine temperature drop to -10 C.
FRIDAY: Mix of sun and cloud with isolated flurries, 30-40 km/h wind from the west, alpine high temperatures around -4 C.
SATURDAY: Scattered flurries with 5-15 cm, 40-70 km/h wind from the southwest, alpine high temperatures around -2 C.
SUNDAY: Cloudy, 20-30 km/h wind from the south, alpine high temperatures around -6 C.
There have been no recent reports of avalanche activity.
Flurries and snow will add to the 10-20 cm low density snow around the region. In exposed areas, moderate south-southwesterly winds have redistributed snow and developed wind slabs around ridge features and into the alpine.
Reports suggest there are two buried layers of surface hoar in the upper snowpack, both 25-50 cm below the surface. In windward terrain the snow may be scoured down to a hard crust from November. In leeward terrain, this crust is 40-80 cm deep. Older crusts can be found deeper in the snowpack and are generally breaking down. In areas with a relatively thin snowpack, the base of the snowpack likely consists of weak faceted grains.
