Avalanche Forecast
Regions: Cascades - South East.
Areas of shallow wind slab will linger on steep wind loaded slopes near and above treeline Monday. North of I-90 and where the snowpack is shallower, a dangerous snowpack structure of strong over old weak snow exists. If you suspect this is the case in this zone, put an extra buffer between you and terrain where large avalanches can run, start and stop.

Avalanche and Snowpack Discussion
Light rain, potentially with areas of freezing rain in protected valleys, and high alpine winds buffeted the East Slopes South zone Saturday. Strong west winds and a few inches of fresh snow late Saturday night through Sunday morning likely formed thin wind slabs on steep lee slopes near and above treeline. We have no direct snowpack or avalanche observations from this area. Take the time to evaluate conditions for yourself before entering avalanche terrain.
Forecast Schedule and No Rating
At this time, we do not have enough specific snowpack information to issue an avalanche hazard rating for the East Slopes South zone. However, even when No Rating is applied, applicable avalanche conditions and backcountry travel advice will be provided throughout the season. When weather systems produce very dangerous avalanche conditions in adjacent zones, NWAC will issue an avalanche warning for this zone as well.
