The snowpack tends to remember weather events better than we do. So when we look back in time, it's easy to forget that as yesterday's storm began materializing, southerly winds were cranking in the 40's and 50's along the high ridges whipping up a batch of shallow, yet predictably sensitive drifts. Problem is... a few inches of snow overnight, covers over yesterday's slabs, making them hard to detect. The good news is... both new and older slabs are isolated to steep, leeward terrain in the wind zone and it's a straight-forward avalanche problem which is easy to detect and easy to avoid. Simply look for and steer clear of fat, rounded pieces of snow, especially those on the north half of the compass and particularly if they feel or sound hollow like a drum.
