Good morning, this is Brett Kobernik with the
The last small storm
produced a well needed refresher and most mountain locations from
Snowpack and Avalanche Conditions:
The light density snow
that fell produced a fairly wide spread natural dry loose snow avalanche cycle
Thursday night which didn’t pose a real great threat. (PHOTO) Many people were able to initiate sluffing on
Friday from slope cuts or from just disturbing the new snow on steeper
slopes. (PHOTO: skier initiated) The slopes needed to be over 35 degrees in
steepness. A few slab avalanches were
triggered as well including one on southeast facing Mt Superior which
reportedly broke 40 feet wide and propagated 50’ above the person who was not
caught. It ran around 800 feet vertical
before going out of sight. I also was
able to initiate a couple of soft slabs in the
The winds are forecast to pick up today which will easily transport this light density snow and form sensitive drifts. The new snow does contain some weakness so I’d expect that the new slabs will be quite sensitive once they start forming. You may also find a few of these that already formed yesterday along the ridges which were demonstrated by a few folks who triggered them as I described. Also keep in mind that sluffing will be likely again today on the steeper slopes but should be manageable for experienced users.
I’d like to remind
everyone that we do have a generally weak deeper snowpack structure that’s
formed so far this year. This latest
storm did not overload it enough to break into deeper layers but today’s
forecast wind event may push it over the edge in many places. Areas around
Bottom Line for the
Today, the avalanche danger is MODERATE on slopes steeper than about 35 degrees which includes sluffing on all aspects and potential for slab avalanches in the wind affected terrain which is mainly higher in elevation. As the wind speeds increase the avalanche danger will rise to CONSIDERABLE on steep, wind drifted slopes. These may break into deeper weak layers which would produce a much more serious avalanche. The avalanche danger is not as great on slopes less then 35 degrees in non wind affected terrain.
Today we’ll see increasing clouds and wind with a chance for snow today and a better chance in the afternoon. 2 to 4 inches is possible. Temperatures will remain cold in the single digits to mid teens and ridgetop winds will be from the northwest gradually increasing through the day until they reach into the 40 to 50mph range this evening. Snow showers will end later this evening.
Yesterday, the Wasatch Powderbird Guides did not fly, and if they can fly
today, they will be in Mineral,
