In sintesi

It will remain possible for you to trigger a Wind Slab today at upper elevations in steep terrain.  Look for fresh slabs that have been stiffened by the wind, especially in more open terrain features as signs of increased danger.  If you're approaching slopes >30 degrees and are finding 8" or more of recent snow (including wind-drifted) error on the side of caution.

    Wind slabs will most likely be found at upper elevations in the Blues, where the greatest snowfall has occurred.  If you observe drifting snow from the wind you can be assured new wind slabs are being formed.  Dune-like formations, pillows, and fresh cornices are all visual clues.  Look for small test slopes to observe signs of cracking as evidence that you should avoid steeper and more consequential terrain.  Use extra caution around slopes leading into terrain traps, which could injure or bury a rider.  

    A stout crust developed earlier this week, which is a good sliding surface for the new snow.  Freshly developed wind slabs will need time to bond to the old snow surface.  

Avalanche Discussion

New snow falling on???  Thanks to the recent observations we've received from the Northern Wallowas and Elkhorns.  It's good to keep in mind the changes that have occurred to the snow surface during the high pressure we've seen this week.  On more shaded aspects we've observed surface hoar and faceting, while on sunny slopes a crust has formed.  This will affect how well the new snow bonds or reacts to the new load of snow in the next 24 hours.  You will have to dig down to determine if the new snow is bonding to the old snow surfaces.  The next step is determining if you have stronger snow (slab) overlying weaker snow.  If this is the case look for safer terrain to recreate in.
