Avalanche Advisory for Tuckerman and Huntington Ravines
Posted: 7:52 a.m., Friday, January 30, 2004

Tuckerman Ravine has LOW and MODERATE avalanche danger. Hillman's Highway, the Little Headwall, the Lower Snowfields, Left Gully and Right Gully have Low avalanche danger. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets. Normal caution is advised. All other areas in Tuckerman Ravine have Moderate avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Unstable slabs are possible in steep terrain. Use caution in steeper terrain.

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.

Snow showers are in the forecast for the higher summits today with little accumulation expected. Winds on the summit have been out of the WNW for the past 35 hours and have managed to move some snow around. Loading has occured in strong lee areas, pimarily on ESE and SE aspects. These aspects are still the areas of greatest concern due to previous loading on the northern side of Tuckerman, namely the Headwall, Lip and Sluice. 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. Be prepared for the potential of 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.

Please Remember:
