Avalanche Forecast
Regions: Cascades - South East.
Deep new snow combined with windy periods and warming has created dangerous avalanche conditions requiring conservative terrain choices Wednesday. Avoid steep slopes greater than 35 degrees, especially higher terrain that received wind deposited snow where you are likely to trigger avalanches. Avalanches could be large and run far and fast.

Snow and Avalanche Discussion
The Cascades East-South zone is receiving significant and incremental loading of weak and likely faceted snow layers from a late January dry spell. Continued moderate snowfall Tuesday night into early Wednesday at warmer temperatures will maintain dangerous avalanche conditions.
Denser wind-driven and warmer snow will load and stress the significant amount of recent cold low-density snow that fell at the beginning of this extended storm cycle, making natural or triggered avalanches likely. We are recommending backcountry travelers use extra caution and choose conservative terrain Wednesday, avoiding steep open slopes greater than 35 degrees, especially near ridges where wind transported snow exists.
Forecast Schedule and No Rating
NWAC has issued an avalanche warning for this zone. At this time, we do not have specific snowpack information from the East Slopes South zone. However, similar weather systems and snowpack structure in adjacent zones will produce very dangerous avalanche conditions. See East-Central zone forecast for the most complete information
