Avalanche Advisory for Wednesday 2-15-2012

Expires at midnight, Wednesday 2-15-2012

Tuckerman and Huntington Ravines have LOW avalanche danger.  Natural and human triggered avalanches are unlikely except in isolated terrain features. The Lower Snowfields and the Little Headwall are not posted due to an overall lack of snow. Forecasts for these locations will begin when conditions warrant.

 A foreboding sky over the mountains is a bit more bark than bite today as weather forecasts are only calling for some flurries and a potential brief snow shower.  A disorganized system will be shuffling along giving the mountains, clouds and fog across the higher landscape of the White’s through the day.  We aren’t anticipating enough snow to make a difference for snow stability to move any avalanche forecasts above ‘Low’.  As always be ready for the mountains to deliver some weather surprises, such as a shot of snow.  However, no weather information is pointing to getting more than a passing shower or two of light intensity.  As we move into tonight and tomorrow the chance of precipitation will increase.  Thursday night and Friday we have a 70% chance of moisture with the potential of 2-4” (5-10cm) to fall before a clearing weekend.  Overall, it will be a cloudy few days ahead with a bit of precipitation each day.  We are continuing to run the fine line between rain and snow due to temperature expectations near the freezing point at mid mountain elevations so stay tuned.

Expect foot travel to be a mixed bag of staying on top due to hard crusts and steel slab styrofoam, or breaking through the surface down in the trees or in protected lee areas that were protected from high winds earlier in the week.  As mentioned yesterday we are continuing to do some hauling on the Sherburne ski trail with our snowcat due to extremely thin coverage on the Tucks Trail.  Talking to two skiers yesterday the cat tracks are chewing up the ice which actually improved the rugged ski conditions.              

Please Remember:

  • 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.
  • Anticipate a changing avalanche danger when actual weather differs from the higher summits forecast.
  • For more information contact the Forest Service Snow Rangers, the AMC at the Pinkham Notch Visitor Center, or the caretakers at Hermit Lake Shelters or the Harvard Cabin.  
  • Posted 8:10a.m. A new advisory will be issued tomorrow.
