Choose conservative, low consequence terrain.
Storm slabs will remain reactive due to the underlying layer of surface hoar and a crust.
Small storm slabs are expected to be reactive due to the large surface hoar beneath them.
Dry loose avalanches are likely where new snow doesn't form a slab.
Several small storm slabs were triggered by skiers in the region on Thursday. These avalanches were triggered on the late January surface hoar layer mentioned in the snowpack summary.
Dry loose avalanches were also triggered by skiers in steep terrain.
By Saturday morning up to 30 cm of snow could overlie the late January surface hoar/crust layer. This new snow has been accompanied by moderate to strong south and west wind, meaning that the crust will likely remain on the surface on southerly aspects and deeper deposits will be found on north and east aspects
The late January surface hoar is largest on sheltered treeline and below treeline features and may not exist on exposed terrain in the alpine.
The snow surface will likely become moist at low elevations and on south aspects as the freezing level rises and the sun comes out.
The mid and lower snowpack is well settled.
