Watch for wind slabs at upper elevations and in extreme terrain.
Continue to verify conditions in your area and practice good travel habits.
Riders may still trigger slabs in extreme terrain, dry loose avalanches are possible if a slab isn't present.
No slab avalanches have been reported in the past 3 days. Skier triggered dry loose avalanches in steep terrain have been reported over the past 3 days.
Up to 5 cm of new snow may accumulate by Sunday morning. This new snow will be accompanied by moderate southerly winds forming wind slab on north aspects. In sheltered terrain this new snow may overlie soft, faceted snow or surface hoar. In exposed terrain it will overlie a sun crust or wind-affected snow.
30 to 50 cm overlies a weak layer from late January. In most areas, it is a hard slippery crust, however, on shady, upper-elevation slopes, it may be faceted grains or surface hoar. This layer hasn't been producing avalanches, but may become a problem when more snow arrives.
The mid and lower snowpack is strong and bonded.
