Location: 1 inch new in Tuckerman’s

Warm overnight temperatures allowed continuous melting of the snowpack up to 4300 feet. The morning low elevation precipitation was in the form of rain changing to snow around 3000 feet. One inch of new snow had accumulated by 1:00PM with the consistency of cream cheese at Hermit Lake. West winds were light gusting to moderate with blowing snow. Temperatures reached 34F degrees by 2:00PM in the mid elevations. A superficial refreeze of the previous days melting snow has created variable crusts. The wind drifted new snow had begun to build slabs up to 4 inches thick and of 4 Finger hardness. The rough texture of the refrozen surface snow has created good bonding with the newly developed wind-drifted slabs. In sun and wind protected areas, such as the trees below Raymond Cataract, you may still find soft wind-drifted slabs from the previous storm cycle. Visibility and the avalanche danger was low with no new avalanches to report.
