Avalanche Advisory for Saturday, 4-27-2013

This advisory expires tonight at 12:00 midnight.

Tuckerman Ravine has Low avalanche danger. Natural and human triggered avalanches are unlikely. Huntington Ravine is not posted. We are no longer monitoring conditions in Huntington this season. You will need to do your own snow stability assessments. A danger of falling ice exists and will persist until it all comes down.

Today and for the foreseeable future, the weather seems to be cooperating enough to make for enjoyable skiing and riding conditions. We’ll see an increase in the cloud cover today, with a slight chance for afternoon showers. On the positive side of the weather forecast, light winds and warm temperatures should allow snow surfaces to soften up during the day before refreezing this afternoon. Tomorrow the weather looks even better,with sunnier skies and slightly warmer temps. All this good weather might lull you into thinking you don’t need to pack so heavy. Conditions today are starting the day frozen and will freeze up again at the end of today. We recommend bringing an ice axe and crampons for travel in steep terrain. You may never even pull them out of your pack, but it’s easy to find yourself in a situation where they would be very helpful, if not critical to getting up or down a route safely.

Falling ice is an increasingly common occurrence at this point in the season. Over the years many people have been severely injured or killed by icefall in Tuckerman, while countless others have had close calls. It’s hard to truly appreciate the seemingly random, unpredictable power of this hazard until you’ve seen it firsthand. Take our advice: Minimize the time you spend in areas where ice may fall from above you, such as under the headwall or at Lunch Rocks. DESPITE ITS POPULARITY, LUNCH ROCKS IS NOT A SAFE PLACE FOR WATCHING THE ACTION. 

Crevasses are opening up in many areas. The worst of these can be found in the Lip area and Center Bowl. The smallest ones may just trip you up a little, but others are far more dangerous. Some are quite deep, others have icy water splashing through them, and some are hidden from view by rollovers or a thin bridge of snow. Hillman’s Highway has some undermined snow and an open hole to watch out for. The best way to avoid this hazard is to know where the holes are located, and avoid these areas. You can do this by climbing up what you plan to descend.

The Sherburne Ski Trail is closed about 1 mile uphill of Pinkham Notch. At the rope, you will need to cross over to the hiking trail and walk down to the parking lot. Do not walk or attempt to ski down this muddy trail below the rope.

The Lion Head Winter Route remains open and offers the most direct access to the summit of Mt. Washington from the east. This is a very steep route and is often more challenging in spring conditions. An ice axe and crampons are highly recommended for this route. The Lion Head summer trail is still closed.

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 Mount Washington Volunteer Ski Patrol, or the AMC at Pinkham Notch Visitor Center.
  • Posted at 7:45 a.m., April 27, 2013. A new advisory will be issued tomorrow.
