The Hermit Lake snow scale and 24hour storm-board agreed with around 4 inches of new snow at 9:30am and it had been snowing for over 3 hours. For most of the morning it was mid 20F degrees, blowing snow, and summit winds gusted over 100mph. A moderate rate of snowfall was observed with around 1 inch/hour. Much of the falling accumulation was in the form of decomposing and fragmented particles with sporadic graupel. Around 13:45 the winds became light from the east and the skies lightened so I looked into Tuckerman Ravine. Extreme east winds had transported much of the new snow out of the ravines ski terrain leaving behind isolated 4 to 10 inch drifts. Smooth slabs of fist to 4 finger soft snow can be found on leeward features that were protected by the wind. No new avalanches were observed on this east facing terrain.
