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.

Yesterday was a pleasant day on the mountain with long periods of sunshine with a bit of intermittent clouds and light to moderate winds. South facing aspects went through periods of absorbing solar heat during the brief lulls of cold wind which kept surface temperatures low. But, in protected areas high in southern aspects snow balled up under crampons so pockets of new slab did consolidate slightly. This is particularly true in locations near the top of Right gully and the Sluice. Although it appeared that very little snow moved around, many ski tracks and boot packs made yesterday have filled in with snow. Once again the biggest concern is the area around and under the Lip on the northern, or climbers right, side of the Tuckerman. Therefore, we still have a bit of Moderate danger. Time has allowed for some bonding to occur and we do feel that the slabs have gained strength. However, January's record cold temperatures have been a large contributing factor to these persistent lingering weak interfaces to resist bonding. Avalanche activity that has occured on these slopes during precipitation events earlier this month has occassionally stepped down into deeper slabs and resulted in large direct action avalanches. While currently we are not as concerned with natural activity, we do have concerns that if a person were to ski or climb in the areas posted at Moderate it is possible they could trigger an avalanche in newer wind slab that may step down to deeper weak layers.

Today and tomorrow mornings beautiful weather will begin to deteriorate Tuesday afternoon as a classic New England "wintery mix" decends on the area. Sleet, and maybe worse, is expected to mix with snow during the initial pulse of precipitation. It is anticipated to move to all snow during the overnight and into Wednesday morning. It will move in from the south before west winds take over on Wednesday. Although most of the moisture is expected to come during the overnight hours expect western winds to have a strong influence on loading eastern aspects on Wednesday. The current models are producing water equivalents of between .75 and 3.2 cm (.3"-1.25"). How much snow this produces will rely greatly on the amount of sleet and "wintery mix" we start with tomorrow. Once again cross all your digits.

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.
