bottom line

Good morning! It's a chilly one out there! Plan on staying bundled up for a while. This cold front looks like it will stick around through the weekend. The snowpack doesn't like the cold either. I expect we'll see the snowpack develop some weaknessess, as a result of this weather.

The longer this cold snap goes, the more stiff and brittle the wind slabs will become. be aware on the edges of slopes, near rock outcroppings or approaching a slope from the bottom. The colder it gets the more trigger-prone the old wind slabs will become. Keep an eye out for signs of instability like...cracking and whomphing.

It's not everywhere, but it's out there! A buried surface hoar layer 12-18'' down in the snowpack won't go away! We are still finding the late Dec layer buried on protected slpopes. Open areas on N facing slopes, near treeline, are the most likely places to find it. Don't get summit fever and blast through the sub alpine to get to the big terrain without analyzing the snow under your feet. The buried SH is alive and well in places it's intact. Don't let it get you by suprise!

Deep intabilities will become a bigger issue during the next warm front. Right now, most of the deep snowpack is protected from influence by a really firm and frozen crust that is bridging the upper portions of the pack. Always keep deep snowpack instabilities in your brain, but there are other concerns that are more pressing at this time.

Disclaimer

Avalanche conditions change for better or worse continually. Backcountry travelers should be prepared to assess current conditions for themselves, plan their routes of travel accordingly, and never travel alone. Backcountry travelers can reduce their exposure to avalanche hazards by utilizing timbered trails and ridge routes and by avoiding open and exposed terrain with slope angles of 30 degrees or more. Backcountry travelers should carry the necessary avalanche rescue equipment such as a shovel, avalanche probe or probe ski poles, a rescue beacon and a well-equipped first aid kit.  For a recorded version of the Avalanche Advisory call (208)765-7323.
