Avalanche Advisory for Tuckerman and Huntington Ravines
Posted: 9:20 a.m., Friday, February 11, 2005

Tuckerman and Huntington Ravines have EXTREME AVALANCHE DANGER. Widespread natural or human triggered avalanches are CERTAIN!! Extremely unstable slabs are certain on most aspects and slope angles. Large destructive avalanches are possible. TRAVEL IN AVALANCHE TERRAIN SHOULD BE AVOIDED. THIS INCLUDES STAYING WELL AWAY FROM AVALANCHE PATH RUN-OUTS. TRAVEL BEYOND HERMIT LAKE AND THE HARVARD CABIN SHOULD BE AVOIDED.

Today is an absolute no brainer. Travel in avalanche terrain should be avoided! If you are considering this as an option make sure you have all your personal affairs in order and your executor has the proper instructions. We have picked up 60cm (24in) of snow and it's still snowing. Winds shifted around to the NW early this morning and are expected to gust to 145mph (90mph). We will have an unbelievable amount of loading at an unprecedented scale for this season. We are certain that widespread avalanche activity will occur. Just to say it one more time, travel in avalanche terrain and the associated run-out paths should be avoided. Expect near zero visibility above treeline. It is definitely a hot tub day. Anticipate an elevated avalanche danger rating through the weekend.

THE LION HEAD WINTER ROUTE IS OPEN. Mountaineering skills and equipment are required on this route. Crampons and an ice axe are a must for safe travel on Mount Washington. The John Sherburne Ski Trail will likely be slow going until enough brave souls sweat some tracks into it.

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:
•   Any new precipitation may increase the avalanche danger, this includes wind transported snow.
 
•   Obtain the latest weather forecast and review archived avalanche advisories at www.tuckerman.org for snowpack history before heading into the mountains.
 
•   For more information, contact the U.S. Forest Service Snow Rangers, the AMC at the Pinkham Notch Visitor Center or Hermit Lake Shelters or the HMC Caretaker at Harvard Cabin.
 
•   This advisory will expire at midnight.
