A weak layer from late January is a concern in shallow north facing terrain in the alpine. Be especially leary of slopes that match this description and have a cornice above.
Storm and wind slabs will be most reactive on sun exposed slopes.
Wet loose avalanches are possible on sun exposed slopes and at lower elevations.
Dry loose avalanches are possible where new snow hasn’t formed a slab or become moist.
On Thursday several small storm and dry loose avalanches were reported in the region. The storm slabs were generally in wind-affected terrain.
Up to 25 cm of new snow has fallen, this new snow will become moist on all aspects and elevation throughout the day on Friday, the exception will be high north facing terrain. Below this new snow is a crust from late March.
A weak layer of facets from late January can still be found down around 1 meter. This layer remains a concern on high north facing terrain where the late March layer isn't present.
The snowpack is quickly disappearing below treeline.
