TUCKERMAN AND HUNTINGTON RAVINES HAVE LOW AVALANCHE DANGER. Natural avalanches are very unlikely and human triggered avalanches are unlikely except in isolated pockets on steep snow covered open slopes and gullies. There is generally stable snow, but these pockets do exist so pay attention as you move through avalanche terrain. Normal caution is advised.

The North or right side of Tuckerman Ravine has more instability than the southern side though still staying within the Low rating. Because of the strong lee nature and our prevailing winds, areas under the Lip, Sluice, and Right gully may have pockets of softer hard slab than the southern side of the ravine. Areas under the Sluice and left of center have wind pack dominating the snowpack. Also be aware that ice crust is interspersed through some areas of the bowl and with the current flat lighting may be hard to ascertain.

Snow showers are forecasted for the morning hours so watch the weather and anticipate an increase in the avalanche danger. If it increases it will depend on the amount, intensity, density, wind speed and direction, and a few other contributing factors.

With the warm weather last week followed by cold temperatures you should anticipate ice dams. Over the past week and a half large dams were witnessed in both Yale and North gullys. We have received reports of water running from ice tool placements in numerous locations so be cautious for hydrolic pressure in commonly found areas such as over the top of bulges and steep columns.

THE LION'S HEAD WINTER ROUTE IS OPEN. Follow the orange Lion Head signs off of the Tuckerman Ravine trail about 1.75 miles up from Pinkham. This is a difficult steep route so crampons, ice axe, and mountaineering skills are essential.

Coverage on the John Sherburne ski trail is fairly good.

 
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 expires today at midnight and the next avalanche bulletin will be issued tomorrow.
