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.
Brisk weather conditions will prevail today in the higher mountains with snow showers likely to bring a bit of precipitation. At 7am the summit had a temperature of -23C (-9F)with winds from the WNW at 120kph (76mph). The forecast expects the temperatures to rise a bit with winds anticipated from the NW at 80-160kph (50 to 100mph). With this broad wind forecast you should look forward to quite gusty conditions. Snow showers may bring a 5cm (2in) of low density snow to the mountains. As long as high winds remain I think most areas will be blown clean to old surfaces except strong lee areas protected by WNW and NW winds. These lee areas would be predominately ESE and SE aspects, but pay attention to cross loading potentials. These aspects are still the areas of greatest concern due to previous loading on the northern side of the Tuckerman, namely the Headwall, Lip, Sluice, and Right Gully, have the most instability. New snow may increase the avalanche danger later in the day so watch precipitation amounts closely and change your plans accordingly. Snow showers are expected to occur on and off into the middle of the weekend before clear skies are expected to return. So be prepared for some changing avalanche conditions over the next few days.
The John Sherburne ski trail has variable conditions. Expect areas of water ice, emerging rocks and abrupt water bars. Be prepared for sudden changes in the trail.
THE LION HEAD WINTER ROUTE IS OPEN. This is a steep and challenging route. Ice axe, crampons, and the skill to use them well are necessary for safe travel. Remember, it is always easier to go up than come down.
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.
