A new advisory will be issued when conditions warrant or within 72 hours.
A General Advisory is in effect for Tuckerman Ravine. You will need to do your own snow stability assessments. A general advisory for Tuckerman will be in effect until complete melt out later this spring/summer. We are no longer monitoring conditions in Huntington Ravine.
Rain showers and periods of fog will continue for Sunday as one weather system exits and another cold front arrives. In between these we may see a brief period of clearing skies, albeit short lived. As rain returns into Sunday afternoon and early evening, expect to see dropping temperatures which should turn rain to snow overnight into Monday. Snow showers are anticipated for Monday before a high pressure system slides in bringing some nicer weather for Tuesday and Wednesday. With cold temperatures on the way expect hard snow surfaces, particularly in the morning. Be sure to look at the Mount Washington Observatory summit forecast at Pinkham Notch before heading up the mountain.
FALLING ICE. Over the years many people have been severely injured or killed by falling ice in Tuckerman. The most hazardous locations are in the center and right side of the ravine, including Lunch Rocks, the Sluice, and under the Lip-Center Bowl area. Warm weather and rain increase the potential for icefall to occur. Avoid spending time in high risk areas such as under the headwall or at Lunch Rocks.
CREVASSES AND WATERFALL HOLES. These are growing larger in many locations, the most dangerous locations are in the Lip and Center Bowl. Give them plenty of room, since they are often much larger beneath the surface than what you can see from above and can be much deeper than you might expect. Breaking through weak snow into one of these could be fatal for you or someone in your group. Give these areas plenty of room when hiking up or skiing down.
UNDERMINED SNOW. As the snowpack continues to get thinner, this problem gets worse. It is most prominent in places where there is flowing water beneath the snowpack, which includes most of the gullies. While the snow may appear thick and strong on top beware that the snow may be bridging this hazard. When in doubt probe aggressively with a ski pole or ice axe. If you see small holes in the snow or near large rocks, realize there may be large open spaces under the surface.
A SECTION OF THE TUCKERMAN RAVINE TRAIL IS NOW CLOSED TO ALL USE. This section extends from Lunch Rocks at the floor of the Ravine to the top of the Headwall where it meets the Alpine Garden Trail. This includes no skiing or riding through the Lip area. Only this section of the trail is closed. This annual closure is due to the magnitude of the crevasses and undermining, and the severe consequences of a fall in this area.
Attention aux randonneurs! Une section du sentier du Tuckerman Ravine est présentement fermé à toutes les activités. Cette section est située entre Lunch Rocks et le sommet du Headwall jusqu’où ce dernier rejoint le sentier du Alpine Garden. Cette fermeture inclut également toute activité de descente dans le secteur du Lip. Seulement cette section du sentier est fermé. Cette fermeture annuelle est due à l’ampleur des crevasses et à la gravité qu’occasionnerait une chute dans ce secteur.
The John Sherburne Ski Trail is closed for the season. Plan to hike down from Hermit Lake.
Safe travel in avalanche terrain requires training and experience. This advisory is just one tool to help you make your own decisions in avalanche terrain. You control your own risk by choosing where, when, and how you travel.
For more information contact the Forest Service Snow Rangers or the AMC at Pinkham Notch Visitor Center or Hermit Lake Shelters. Issued Sunday May 12 2013. A new advisory will be issued when conditions warrant.
