Avalanche Advisory for Tuckerman and Huntington Ravines
Posted: 8:32 a.m., Wednesday, February 1, 2006

Tuckerman Ravine currently has CONSIDERABLE and MODERATE avalanche danger. The Headwall, Lip, Bowl and Right Gully have CONSIDERABLE avalanche danger. Natural avalanches are possible and human triggered avalanches are probable. Be increasingly cautious in steeper terrain. All other forecast areas in Tuckerman have Moderate avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain. We have temporarily stopped forecasting for the Little Headwall due to a lack of snow but are close to resuming forecasts for this area.

All forecast areas in Huntington Ravine have MODERATE avalanche danger. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain.

Let's all welcome February with open arms as we give January a kick out the door. The last month provided a measly 33"(84cm) of snow at Hermit Lake and even a few uncalled for soakings of winter rain. Today we greet the new month and the winter weather it brings. During the last couple days of January the Summit picked up 5.2"(13.2cm) of snow while lower down we got a little bit more. Winds have been fairly light and only last night did they make their way around to our favorite location, the NW. They're currently blowing pretty steady in the mid to upper 40's mph(70's kph) though they are forecasted to die down by the afternoon. As with many things in life, timing is everything. We are currently at the posted ratings with active loading occurring for the first time since much of this snow has fallen. The winds that we first saw with recent snowfall were out of the S & W with speeds just slightly slower than those currently occurring. SE aspects are now getting their first significant dose of wind transported snow since Saturday night. Any snow that is being blown onto these slopes is potentially falling on unconsolidated snow, thereby creating another red flag for snowpack instability. The areas in Huntington that have S & SE aspects are currently on the upper end of the Moderate rating. If the winds steadily die down to 5-15mph(8-24kph) by early afternoon as expected then we will see the chance for natural avalanches fall off. At this point some areas will move toward the lower end of their current rating or even jump down to the upper end of the next lowest rating. If winds continue to blow at the current speeds for more than a few hours then you can expect areas to climb toward the next higher rating.

The Lion Head Winter Route is open. Mountaineering skills and equipment are required for safe travel on this route.

The Sherburne Ski Trail is open with recent snow concealing dirt, long sections of water ice, deep waterbars and eroded water channels that can grab a ski tip very quickly. Expect variable conditions as the new snow conceals all types of buried treasure.

Please Remember:
•   • It is impossible to accurately predict natural events, such as avalanches, in every instance. This Advisory is one tool to help you make your own decisions in avalanche terrain. It should be used along with safe travel techniques, snow stability assessments, an understanding of weather's effect on the snowpack, and proficiency in avalanche rescue.
 
•   • You should obtain the latest weather forecast before heading into the mountains. Anticipate a changing avalanche danger when actual weather differs from the National Weather Service forecast.
 
•   • For more information, contact the U.S. Forest Service Snow Rangers, the AMC at Pinkham Notch Visitor Center or Hermit Lake Shelters, or the HMC caretaker at the Harvard Cabin. This avalanche advisory expires at midnight.
