Huntington Ravine has CONSIDERABLE AND HIGH avalanche danger. The Escape Hatch and South gully have Considerable avalanche danger. Natural avalanches are possible and human triggered avalanches are probable. Be increasingly cautious in steeper terrain. All other areas in Huntington Ravine have High avalanche danger. Natural and human triggered avalanches are likely. Unstable slabs are likely on a variety of aspects and slope angles. Travel in avalanche terrain is not recommended.

The summit received approximately 18 cm (7 in) of new snow in the past 24 hours. Hermit Lake picked up 42 cm (16.5 in) since late yesterday and has an average density of 8%. This new snow has come in with SE and E winds which has done little loading up to now. However, currently the center of the passing system is passing through southern NH which will wrap the winds quickly around as the day progresses. Winds should be out of the North by around noon and then out of the NW between 2 and 3 pm. As this occurs, with more new snow, loading will begin on South aspects which were loaded heavily by last week's storm. As winds continue around to the NW heavy loading should occur in most areas of the Ravines. Although we are not quite at High yet we will be by later in the day as the winds do the quick wrap around to our prevailing westerlys. So expect a rising avalanche danger as winds load new heavier density slabs on loose light densities from earlier in the storm.

This storm system will be followed by some clearing tomorrow then followed by another weather maker due to arrive on Wednesday. Temperature regimes are still a bit unclear so whether we get a mix of snow, freezing rain, and rain or not is still a question. We'll keep tabs on this and give more details as the storm continues to develop.

The John Sherburne ski trail is improving with this storm, but the deep new blanket should make it slow going till it becomes broken out. Expect abrupt waterbars, patches of water ice, and rocks under the new snow.

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.
