Strong SW winds blew and drifted snow with a vengeance on Sunday creating slabs 12"-18" deep on slopes facing NW-N-NE-E near treeline and above, with some cross-loading possible on upper elevation slopes facing the south side of the compass. In addition, blustery, NE winds will likely form some shallow, fresh slabs above treeline today. Look for fresh deposits on the leeward sides of gully walls, sub-ridges, and rocky outcrops. Deeper drifts that formed during Sunday will be more stubborn to trigger today and you may have to get further down slope before they release. The best policy is to continue to avoid steep, wind drifted northerly aspects, especially on the bigger, more consequential terrain above treeline. Time, and warm temperatures today should help stabilize this problem.
