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 FOR THE REST OF THE SPRING.

TUCKERMAN RAVINE HAS MODERATE AVALANCHE DANGER. Natural avalanches are unlikely and human triggered avalanches are possible. Use caution in steeper terrain and be prepared for an

increasing avalanche danger today. Variable conditions will be found in the Ravine today. Expect some areas to be covered with only a thin coating of snow while stong lee areas protected from winds may have deep new pockets.

The summit received 4.4 inches (11 cm) of snow in the past 24 hours with variable winds and temperatures. Temps started in the teens Sunday morning when the snow began with winds flexing back and forth between SE and S peaking around 50-55 mph. Temperatures rose to 36 degrees with a short period of light rain in the ealy morning hours before temperatures dropped again into the lower twenties where they are currently. Winds are now out of the west hovering around 20 mph with temperatures expected to drop into the low teens through the day. Snow showers are predicted for the day so EXPECT AN INCREASING AVALANCHE DANGER WITH THE POSSIBILITY OF THE AVALANCHE RATING GOING TO 'CONSIDERABLE' IF WE RECEIVE ENOUGH PRECIPITATION. MORE SNOW IS FORECASTED TONIGHT AND ON AND OFF THROUGH THE WEEK SO 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. As Brad mentioned in Sundays advisory avalanche conditions could be like riding on a see-saw this week with changing conditions. Be prepared for the avalanche danger danger to go up and down so 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. 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! 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. 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.
