Tuckerman and Huntington Ravine currently have
CONSIDERABLE avalanche danger. Natural avalanches
are possible and human triggered avalanches are
probable. Be increasingly cautious in steeper terrain.
The Lower Snowfields and the Little Headwall in
Tuckerman both have Low avalanche danger. Avalanches
are unlikey except in isolated pockets. Normal caution
is advised.
The summit reported 10.4 inches of snow over the
past 24 hours. This began at roughly 7 am Saturday
morning with very light winds. Winds stayed in the
single numbers till about noon when they shifted
out of the NW-WNW and within several hours were
blowing over 100 mph with a peak of 112 mph. We
received a couple of inches of loose unconsolidated
snow before the winds began to pick up, this created
a slab over the now weak uncosolidated layer. An
enormous amount of snow blew into lee areas during
the peak precipatation period between noon and midnight
due to high NW-WNW winds this generated avalanche
activity in Hillmans Highway, Left gully, the Chute,
the Bowl, the Lip and most likely to NE in the Sluice
and the Right gully. Crown lines are still crisp
on the Left, or South side, of the Ravine but as
you move towards the center they become filled in
and "muted". On the right side fracture lines are
not visible. Due to the NW winds they have likely
been filled back in with new snow after sliding.
So be aware the Lip, Sluice and Right gully have
been reloaded with significant amounts of new snow.
THE LION'S HEAD WINTER TRAIL IS NOW 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 improving
but expect some rocks, waterbars, and brush hidden
just below the snow.
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 at midnight and the next avalanche
bulletin will be issued tomorrow.
