Huntington Ravine has LOW avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised.
The summit received 6 cm (2.4 in) of new snow in the past 24 hours and expect snow showers to continue during the first half of the day. High W, WNW, and NW winds loaded many areas in Tuckerman with new snow and a few locations in Huntington. This loading will continue with any new snow today. Some examples of new loading can be found in the Lip and pockets in the bowl of Tuckerman as well as the lower half of Central gully in Huntington. These areas are both E and SE facing aspects.
Wednesday's 10.9 cm (4.2") rain caused several wet loose and slush avalanches in Huntington Ravine. O'Dells, Pinnacle, The Harvard Bulge, Yale, and Damnation all presented evidence of wet debris this morning. With the falling temperatures, ice dams should be expected throughout both ravines.
The John Sherburne ski trail was hit hard by the rain, but still has good coverage. However, expect very icy and hard conditions, some blowouts, abrupt water bars, open holes, and running water in places.
THE LION HEAD SUMMER TRAIL IS CLOSED AND THE WINTER ROUTE IS OPEN.
AS ALWAYS, THIS ADVISORY IS ONE MORE TOOL TO HELP YOU MAKE YOUR OWN DECISIONS IN AVALANCHE TERRAIN. It should be used along with your own snow stability assessments, knowledge of safe travel techniques, skill in reading mountain weather's effect on the snowpack, and avalanche rescue.
