AVALANCHE ADVISORY
Thursday, December 15, 2005 7:30am
Good morning,
this is Brett Kobernik with the
UDOT will be sighting in the howitzer in
The beacon locator park at Snowbird is now open and
free to the public. It’s sponsored by
Wasatch Backcountry Rescue and Snowbird and located just off the bypass road in
upper Little Cottonwood Canyon.
Current Conditions:
Current temperatures at most mountain locations are around 10 degrees and wind
speeds are generally less then 10 mph from the northwest.
Avalanche Conditions:
You have to be pretty cagey to find decent snow and untracked terrain in the Wasatch but it is still possible. Unfortunately, it is not very abundant since
the winds from Tuesday really did a number on the snow surface. These winds also contributed to some wind
drifts which may still be sensitive to the weight of a person. While most of these drifts seem to stay in
place, I don’t trust all of them and I’m giving them some more time before I
get on them especially in areas where I am exposed to rocks or trees below.
Since there is not a lot going on avalanche wise,
our attention shifts to the snow surface and what it will be like when we start
adding snow on top of it. Lots of areas
have recrystalized snow on the surface which can make for a weak layer once it
is buried. Also, the recent skiff of
light density snow that we received could be prone to quick faceting which
would also add weakness once buried. If
you’re getting out in the mountains, it would be wise to mentally inventory the
pattern where this weakness is for future storms. Look for sugary snow or “loud powder” forming
on the surface. Also, keep in mind that
there are a variety of crusts that could provide a good bed surface for
avalanches to slide on. Give us a call
or e-mail us and let us know where you are finding these conditions.
Bottom
Line:
For today most
slopes have a LOW
danger. Since isolated sensitive wind
drifts might still be found today, a MODERATE danger exists on slopes steeper then
35 degrees along the upper ridgelines and generally on north through southeast
facing slopes.
Mountain Weather:
Today we’ll see
mostly clear skies with ridgetop temperatures in the upper teens. Ridgetop winds will be from a northerly direction
generally less then 10 mph.
On Friday we’ll see increasing clouds in front of another storm that will
brush by the area bringing another small chance of minor snow
accumulation. Wind speeds will not be as
strong with this storm as they were with the last.
A series of weak systems will affect the area into next week with a
larger system shaping up for late in the week.
