WE ARE NOW POSTING BULLETINS ON AN AS NEEDED BASIS AS CONDITIONS CHANGE SO YOU MAY NOT SEE A NEW BULLETIN EVERY DAY. WE ARE THROUGH FORECASTING FOR HUNTINGTON RAVINE FOR THE SEASON. YOU WILL NEED DO YOUR OWN STABILITY ASSESSMENT WHEN ENTERING THE AREA. THERE WILL BE A DANGER OF FALLING ICE (GLACE EN CHUTE) FOR THE REST OF THE SPRING.

TUCKERMAN RAVINE HAS CONSIDERABLE AVALANCHE DANGER. Natural avalanches are possible and human triggered avalanches are probable. Be increasingly cautious in steeper terrain and be prepared for

an increasing avalanche danger today. Variable conditions will be found in the Ravine.

The summit received 4 inches (10 cm) of snow in the past 24 hours from 6am to 6am with only an inch (2.5 cm) here at Hermit Lake. The models are expecting a few more inches today possibly changing to sleet, freezing rain, and perhaps rain at lower elevations. Snow overnight into this morning has pushed the danger from Moderate to Considerable. But if we do receive a few inches today with increasing winds followed by rain be ready for the rating to go to High. Rain on top of an already unstable snowpack can make for very unstable conditions potentially triggering a natural avalanche cycle. On the other hand if we receive a small amount of freezing rain or sleet, but not quite enough for wide spread natural activity we may see a icy glaze form over the existing snow. Precipatation is expected to change back to snow after the freezing rain/rain event and may possibly become loaded on top of new icy surface. This will be followed by increasing NW winds which the models predict to go over 100 mph tomorrow. THERE ARE MANY POTENTIAL REASONS FOR AVALANCHE ACTIVITY ALL OF WHICH POINT TO AN INCREASING AVALANCHE DANGER. ALTHOUGH IT IS ALMOST MAY, PAY ATTENTION FOR AVALANCHE POTENTIAL IN YOUR MOUNTAIN TRAVELS. THIS INCLUDES MANY AREAS OUTSIDE OUR FORECAST AREA LIKE THE SNOW FIELD TRAVERSES ON THE LION HEAD SUMMER TRAIL. WE COULD HAVE A TOUCHY SITUATION HEADING INTO WHAT IS PREDICTED AS A DECENT WEEKEND WEATHER WISE. WHEN THE WEATHER IS GOOD, THE CROWDS WILL COME. REALIZE WE MAY VERY WELL BE IN A FULL WINTER AVALANCHE SCENARIO. REMEMBER WHEN SOMEONE HEADS UP A SLOPE IT DOESN'T MEAN IT'S SAFE. IT MAY JUST MEAN THEY DON'T KNOW WHAT THEY'RE DOING. THINK TWICE BEFORE FOLLOWING. We had three people get caught in two avalanches yesterday. None of those involved had any avalanche equipment, Ie. beacon, probe or shovel. Up to 11 people were in the area at the time so I believe we were lucky more weren't caught. One slide ran 800 feet before settling midslope and the other ran about 600 feet stopping at the transition with the flats.

MORE PEOPLE IN THIS COUNTRY GET CAUGHT UNDER A MODERATE FORECAST THAN ANY OTHER BECAUSE OF THE HUMAN FACTOR. "WELL MODERATE ISN'T TO BAD" IS A COMMON THOUGHT FOR MANY WHO ARE LITERALLY... DYING TO SKI. REMEMBER, PEOPLE DO GET CAUGHT IN MODERATE AVALANCHE DANGER. Use all your avalanche skills when venturing into the mountains.

The lip area is nearing the point where it will need to be closed with the narrow snowband and the many open and some hidden crevasses. New snow is also hiding numerous holes here and around the Ravine. It is best to avoid this area. CLIMB UP WHAT YOU PLAN ON COMING DOWN TO AVOID ANY SURPRISES. PLEASE take off your skis to walk 40 yards rather than ski over fragile alpine vegetation when leaving areas like Hillmans Highway and the Lower Snowfields. Many of those little trees are over 100 years old.

BE AWARE OF FALLING ICE (GLACE EN CHUTE)! Each year over 1000 tons of ice forms on the headwall in Tuckerman Ravine and the gullies of Huntington Ravine. In the spring it all comes down, often in pieces larger than cars. Many folks have been injured and even killed by falling ice (glace en chute). Pay attention to where you are, do not linger under ice. Have a plan in mind about what you will do if ice comes down. Station yourself near a large rock to duck behind in the event of ice fall. BE ICE SMART!

THE LION HEAD SUMMER TRAIL IS OPEN. Realize the summer trail still has large steep snow traverses. A fall here may see you going over a cliff band so you will need crampons and an ice axe to travel safely in this area. These snowfields may also be an excellent sliding surface for avalanche activity in the event we get more snow. This is always a possibility during April and May at 5000 ft. MOUNTAINEERING BOOTS, CRAMPONS, AND AN ICE AXE ARE NEEDED!

THE JOHN SHERBURNE SKI TRAIL IS NOW CLOSED TO ALL USE. Just because you see snow in back of the rope it is only continious for the first 200 feet. After that you are in mud most of the time. This is the truth. TO PREVENT EROSION TO THE SKI TRAIL PLEASE USE THE TUCKERMAN RAVINE TRAIL FOR HIKING BOTH UP AND DOWN FROM PINKHAM NOTCH. There is no skiing or riding allowed on the Tuckerman ravine trail.

 
PLEASE REMEMBER:
 
• Any new precipitation may increase the avalanche danger, this includes wind transported snow.
 
• Obtain latest weather forecast before starting out.
 
• For more information, contact the U.S. Forest Service Snow Rangers: AMC at Pinkham Notch Visitor Center or Hermit Lake Shelters.
 
• This bulletin will be updated on an as needed basis as conditions change.
