Hello and good morning, this is Toby Weed of the
Current Conditions:
You’ll find a nice dusting of cold
powder in the mountains today, with the Franklin Basin Snotel picking up around
4 inches overnight. The total snow stake up at the Tony Grove site shows around
23 inches on the ground, with 3 new inches of cold smoke. It’s a bitter 2 degrees at the
It’s a good idea in the early
season to practice with all your rescue equipment. I recommend putting a transmitting beacon in
your pack and burying it for you partners to find using their probes. Now is a good time to work out any bugs in
your party’s rescue preparedness.
Avalanche
Conditions:
The weak faceted snow from the early
season is slow to heal. Two people took
nasty rides and sustained injuries in separate avalanches in the backcountry
near
The possibility of persistent slab
avalanches still looms. This problem is limited to upper elevation shady slopes
that had snowcover before Thanksgiving. Many slopes are plagued by large
grained depth hoar to the ground, while others sport crust-facet sandwiches
with crusts varying in strength and thin very weak layers made up of sugary
snow above and in between them. The slab depths where I dug test pits yesterday
were in the 16 to 20” range. Watch for
obvious signs of instability like collapsing or woomphing
noises, hollow sounding snow, and shooting cracks. Reassess your route if any of these signs of
unstable snow are present.
Bottom Line:
The danger is MODERATE
on shady upper elevation slopes steeper than about 35 degrees. Dangerous human triggered avalanches are possible
on some slopes with weak preexisting snow.
Mountain Weather:
Very cold temperatures and a few
snow showers will persist over the region today as an active weather pattern
continues. A weak ridge will build over
the region today and valley inversions will start to build. A storm system will pass well to our north on
Saturday night, bringing a few clouds and a minor threat for a few snow flakes. The next chance for significant snowfall
comes late Tuesday into Wednesday.
