TUCKERMAN AND HUNTINGTON RAVINES HAVE LOW (FAIBLE) AVALANCHE
DANGER TODAY. Natural avalanches are very unlikely
and human triggered avalanches are unlikely. There
may be isolated pockets of unstable slabs on steep
snow covered open slopes and gullies. Normal caution
is advised.
Yesterday's weather didn't pan out quite as we thought,
the rain ended sooner than forecasted so we never
reached the high avalanche danger we were anticipating.
The water percolated into the snowpack with temperatures
into the 40s. This warm water brought heat down
into the snowpack. A cold front moved in early last
evening bringing very cold temperatures, freezing
up the free water in the snowpack. Snow showers
are forecasted on and off this week. Any new snow
will be sitting on top of the frozen snowpack. As
you travel in the ravines you'll want to pay attention
to areas of new snow.
Some small ICE DAMS and multiple water gushers were
witnessed Saturday in Huntington Ravine by several
climbers. With colder weather forecasted after this
warm spell with rain, you should once again anticipate
ice dams this week. This has been a common theme
this winter due to our extreme temperature swings.
There have been numerous close calls this winter
so be prepared for this climbing hazard.
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. Use caution
on the trail a s there are areas where the rocks
are showing. Please stay on route to minimize climber
impacts to the area. Consider it good practice to
move slow and thoughtfully with crampons on rock.
This is a difficult steep route so crampons, ice
axe, and mountaineering skills are essential.
The ski trail has good coverage but is pretty firm
after the rain yesterday and the current cold temperatures.
There are a couple of areas of water ice lower on
the 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 expires today at midnight and the
next avalanche bulletin will be issued tomorrow.
