Avalanche Forecast
Regions: Cascades - South East.
The snowpack is stabilizing, but you can still trigger an avalanche on lee slopes at upper elevations, especially near the Cascade crest. Look for signs of wind transported snow such as cornices and pillow-like snow features. Avoid lee slopes above 35 degrees where you see these signs.
Discussion
Heavy new snow and wind, combined with a warming trend created widespread natural and skier triggered avalanche activity at nearby White Pass Ski Area on Monday. Similar avalanche activity is most likely to linger at upper elevations and on lee slopes. You may be able to trigger 6-8†slabs where you find wind affected snow above lower density snow or sitting above a firm crust.
At lower elevations, snow turned to rain on Monday and many weather stations in the zone were above freezing all day Tuesday. As temperatures lower again Tuesday night, challenging travel conditions will likely be the biggest concern.
Forecast Schedule and No Rating definition
We do not have enough specific snowpack information to issue an avalanche hazard rating for the East South zone. However, even when No Rating is applied, applicable avalanche conditions and backcountry travel advice will be provided throughout the season - this forecast is updated every day, all winter long! When weather systems produce very dangerous avalanche conditions in adjacent zones, NWAC will issue an avalanche warning for this zone as well.
