Strong SW winds blew and drifted snow with a vengeance yesterday. Slabs of wind drifted snow 1'-2' deep are the most widespread on slopes facing NW-N-NE-E above treeline, and these slopes should unequivocally be avoided today. With the strength of the winds, slabs have also developed far down slope, and it's splitting hairs trying to determine where " near treeline" ends and "above treeline" begins. Personally, I'd avoid all steep, mid and upper elevation, northerly facing slopes today. On all other aspects, remain on the lookout for recent deposits of wind drifted snow where terrain features can make all the difference. Look for fresh deposits on the leeward sides of gully walls, sub-ridges, and rocky outcrops. Look for signs of instability such as cracking in the snow surface and avoid steep slopes with recent deposits of wind drifted snow.
