Avalanche Advisory
Advisory: Skyline Area Mountains Issued by Brett Kobernik for Sunday - January 1, 2017 - 6:53am
bottom line

The avalanche danger is generally LOW in the majority of the terrain. There is a "pockety" MODERATE avalanche danger along the higher more east facing steep terrain where isolated wind drifts could be triggered by a person. If you are getting into steep terrain, only put one person on the slope at a time and make sure everyone is clear of the avalanche run-out zone at the bottom.




current conditions

It was another great day up in the hills on Saturday with light wind and plenty of sun. Snow conditions are a mixed bag but there is still great snow for riding out of the wind and sun effected terrain.

During my travels over the last few days I've been finding more weak snow that has formed on the snow surface than I like to see. This is not an avalanche concern for today but could be once we add more snow with the upcoming anticipated storms early next week. I'm not 100% sure this weak surface snow will cause problems once it's buried but it's something to have on your radar. Check the observation below for more details on this weak layer:

description

Wind slabs that formed during the past week seem very stubborn at this point and it is unlikely that a person will trigger them. However, in the very steepest terrain there is still a remote chance that one of these could release on you. They are most likely on the lee sides of the ridges that face north through east.

weather

It looks like not too bad of a day ahead today with partly cloudy skies, ridgetop temperatures in the mid 20s and light to moderate speed southwest wind. The wind will probably increase a bit later today. The long range looks rather stormy. We'll see the first in a series of storms start late Sunday night and we could see 6 to 10" by mid day Tuesday. Temperatures are going to drop into the low teens and perhaps single digits and remain cold for much of the week. It looks like wind will be moderate to strong from the west southwest for much of the week. We should see continued periods of snow from Wednesday on through the weekend.

general announcements

We will publish full detailed advisories Saturday and Sunday mornings by 7am. We will also be publishing basic avalanche danger ratings & info during the week.
