Northwest Inland.
Strong northeast winds have created wind slabs in exposed terrain. Use added caution, particularly if you notice the snow stiffening during your travels.

Weather Forecast
SUNDAY NIGHT: Clear skies, strong northeast wind, alpine temperature -21 C.MONDAY: Mostly clear skies, light to moderate northeast wind, alpine temperature -16 C.TUESDAY: Mostly clear skies, light north wind, alpine temperature -8 C.WEDNESDAY: Mostly cloudy with light snowfall, light northwest wind, alpine temperature -7 C.
Strong northeast winds have redistributed the recent 20 to 40 cm of storm snow in exposed terrain, forming wind slabs. This snow overlies previously wind-affected snow in the high alpine and a widespread melt-freeze crust elsewhere. In the central and northern parts of the region, the storm snow may sit on feathery surface hoar crystals in sheltered terrain at all elevations.In the south of the region, the remainder of the snowpack has been reported as well-settled.Around and north of Hazelton, 50 to 100 cm of snow may overly two weak layers of surface hoar or sugary faceted grains.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
