Good morning, this is Bruce Tremper with the
I have issued a Special Avalanche Advisory today for
the mountains of northern
Strong northwest winds
at upper elevations yesterday and last night caused quite a bit of wind damage
but in wind sheltered areas about 10 inches of very light powder remained on
somewhat denser underlying snow. (VIDEO of yesterday’s
Winds died down quite a bit this morning and temperatures remain cold—around 5 degrees but all this will change in a hurry today because I’m expecting much warmer temperatures and strong winds and a foot of snow today.
Snow and Avalanche Discussion:
avalanches occurred yesterday because of the strong northwest winds. Two slides occurred in Little Cottonwood
Canyon on the south facing slopes and one occurred in Provo
Canyon in similar terrain. None of
these slides hit the road. This morning
at 1:30 am, White Pine in Little Cottonwood Canyon ran naturally, depositing up
to 10 feet of debris on the road. The
road was closed overnight and they will try to do avalanche control this
morning and reopen.
We have a vigorous storm arriving today with very strong westerly winds expected to blow 60 mph, gusting to 80, in the higher terrain, plus rapidly rising temperatures and denser snow, which will all slam down on top of the very light, foofy snow from yesterday morning. It doesn’t take an avalanche scientist to see that it adds up to trouble. Yesterday’s wind slabs existed on more localized terrain but today’s storm will create widespread areas of sensitive, soft slab avalanches at a variety of aspects and elevations.
Bottom Line for the
avalanche danger is CONSIDERABLE and will rise to HIGH by about mid day with the arrival of the
storm. Backcountry travelers should
avoid crossing, or crossing underneath, any slope approaching 35 degrees or
steeper. This danger may occur on most
all aspects and elevations including the foothills. Human triggered and natural avalanches,
especially in wind affected terrain are likely.
A strong storm will
