Yesterday the forecast wind and snow did not materialize. However, winds on Sunday and Sunday night were strong enough to blow the light surface snow around and winds may be gusty at times today at upper elevations. Winds have already bumped up a bit this morning. Today it will be important to watch for blowing snow and wind slabs in steep wind exposed terrain near ridgetops, on convex rollovers, or in cross-loaded gullies. Look for stiff wind affected snow and cracking in the snow around you. Even a small wind slab triggered in high consequence zones can be quite dangerous if you get knocked off your feet. As always, keep a close eye on the surface conditions and know your escape routes if a small slab happens to break under you.
Cornices: Give cornices plenty of room and limit your time traveling below them.
Sluffs: Be aware of loose snow avalanches moving in steeper terrain wherever there is soft snow at the surface. With enough volume these can pick up momentum, enough to carry a person, and can be particularly dangerous if you are caught above terrain traps like cliffs, rocks, or gullies.
