for the Wasatch Plateau/Manti Skyline Region, including, but not limited to

January 22nd, 2005 at 7:30 a.m.

register.
Current Conditions:
With no end in sight to our high pressure system, make sure you do
not forget your sunscreen and sunglasses if you are heading out on the
skyline. Good settled powder conditions
can still be found on shady northerly aspects, while the southerly slopes will
have a mixed bag of crust and supportable snow before the sun hits them and
some soft glop later on in the day-great corn conditions can be found with the
right timing. The roads are in great
shape, just make sure you park with in the white lines off of the travel lanes.
The Mammoth/Cottonwood SNOTEL site has 42” of snow on the stake. The Miller Flat Reservoir Trailhead has 42”
of snow on the ground. It is currently
17 degrees out on the Skyline.
Mountain Weather:
Sunny and warm as far as the eye can see…
Today...Mostly sunny. Highs at 8000 feet
in the upper 40s.
Tonight...Mostly clear. Lows at 8000 feet in the lower 30s.
Sunday...Mostly sunny. Highs at 8000 feet in the upper 40s.
Avalanche Conditions:
Our last recorded snowfall and observed avalanche activity is now
about 10 to 12 days in the past. Since
then temperatures have skyrocketed, with highs yesterday into the mid
50’s! What does this mean for our
snowpack stability? We have three
concerns right now. The first, although
diminishing in probability is still the SCARY possibility of triggered a large
slab on steep and shady slopes that have not avalanched recently. The second concern is for wet snow slides on
sunny aspects, and especially lower elevations, as the day heats up-watch your
consequences, make sure these heavy, slow and concrete like avalanches don’t
take you into any objects. Once you
start to see rollerballs it is time to leave that terrain. Finally, don’t venture out too far onto the
monster cornices that are lingering everywhere on the skyline, keep back
further than you think! This means an
overall avalanche danger of MODERATE on the
aforementioned terrain.
Thanks for calling…this advisory will be updated by Sunday
morning.
