Good Morning. This is Evelyn Lees with the
Current Conditions:
A few light snow flurries
have been reported in the mountains this morning. While no measurable snow fell over night, most
areas received 1 to 3 of thick snow from the last disturbance. Yesterday, the rain/snow line was near 7,500 at
times, and what was falling at the higher elevations was generally over 10%
density. Winds are from the west-northwest
and quite light, in the 5 to 15 mph range.
Temperatures are slightly cooler than yesterday morning, near 20 at
10,000, and near 30 at 8,000. Turning conditions
are surprisingly good in the thick powder on shady slopes, and the dense snow is
making the crusts more friendly.
Avalanche Conditions:
It takes unreasonably warm
temperatures have us worrying about wet snow sluffs and slabs in the month of
January. Yet yesterday, the few inches
of dense new snow were sluffing easily on steep slopes. And today,
the expected 1 to 3 of dense snow could just be enough to tip the balance on some
steep slopes.
At mid and low elevations, where
there is a shallow punchy snowpack, once a sluff gets moving, it could gouge to
the ground or even trigger a damp slab. A
few natural sluffs are possible at lower elevations. So be especially careful to avoid terrain
traps such as gullies where even a small sluff can pile the snow up deeply.
At the upper elevations, it
will be possible to trigger both sluffs and the shallow wind slabs that have
been forming along the ridges. Once
triggered, they have the potential to break into the weak snow below the thin
sun and wind crusts, creating a larger wider slide.
So today, be alert for an
increasing avalanche danger. If you are
in an area that receives more new snow than expected - 3 or more inches - or in
an area where the winds pick up and start drifting the snow, the danger will
rise rapidly.
Bottom Line (SLC,
If we get more than a couple
inches of snow today, the danger will rise to MODERATE on slopes steeper than about 35 degrees,
especially with recent wind drifts. There is a mostly LOW avalanche danger on slopes less steep than
35 degrees.
Mountain Weather:
Another weak weather system is
moving into the northern mountains this morning. Storm totals should be about 1 to 3 today,
of about 10% density snow. High
temperatures will be in the low to mid 30s at 8,000and in the low to mid 20s
at 10,000. The rain/snow line should be
a bit lower than yesterday, around 6,000.
Winds will be from the northwest, and increase into the 10 to 20 mph
range. Tonight, skies will start to
clear as the atmosphere dries out and a ridge builds over us for Sunday. Another weak system is expected for Monday
into Tuesday.
