Field observations over the last two days have reported variable wind directions and notable transport above treeline and along high-elevation ridgetops. Wind velocities are expected to drop significantly today, limiting the potential for continued slab development. Isolated wind slabs may be possible to find near and above treeline, particularly in high-elevation catchment zones and in extreme terrain. Remember that even a small avalanche can have significant consequences in more complex terrain. Large drifts, recent cornice growth, stiff, hollow-feeling snow, and uneven snow surfaces are all clues that indicate nearby wind deposits. Conduct your own localized assessments and be suspicious of terrain features that encourage drifting, such as the leeward sides of ridgelines, alpine couloirs, gully features, and cross-loaded depressions.
Freshly loaded terrain features in the high alpine like this are areas that may be problematic today.
