In sintesi

The avalanche danger is LOW and normal caution is advised. On northerly-facing slopes at the upper elevations, triggering an avalanche 1–2 feet deep on our PWL (persistent weak layer) is unlikely but not impossible. Take advantage of the beautiful weather to practice your companion rescue (beacon/probe/shoveling) techniques.

There is 1-2 feet of snow on slopes facing northwest through east at the upper elevations. Clear skies over the past week have weakened the snowpack and on many northerly slopes, the entire snowpack has become faceted and unsupportable. But in some spots, there remains a stronger, more cohesive slab on top of weak facets near the ground and it is on these slopes where the possibility of triggering an avalanche - although unlikely - remains.

For now, the weak snow found on northerly aspects is not an issue, but it will become a problem once we receive a large enough load of new snow. Read more on this faceting process below.

Special Announcement

The 17th Annual Utah Snow and Avalanche Workshop (USAW) is on Saturday, December 7th at the University of Utah, with an amazing lineup of speakers. Information and tickets are available here . We'll see you there!

Recent Activity

No avalanches were reported from the backcountry, but we continue to receive several excellent observations.

Snow and Weather

Nikki Champion's Week in Review - which summarizes significant snow and avalanche events over the past week - is now available. Although this is mostly specific to the Salt Lake mountains, this will be an indispensable resource for your planning this season.

This Morning: Skies are clear and temperatures are in the upper 20's and low 30's F. Winds are from the north and light, gusting near 20 mph along the highest ridges.

Today: Sunny with temperatures rising between 35 - 45 F. Winds will be from the north and remain light.

This Weekend: Sunny on Saturday with a cold front for Sunday. Snow (am I really saying that?) will develop Sunday night into Monday, with a few inches possible by late Monday.

Current Snowpack Coverage: There is 1- 2 feet of snow on northerly aspects at the mid and upper elevations, with slopes facing east and west appearing moth-eaten. South-facing slopes are turning bare. Dave Kelly was traveling along the North Ogden Divide on Tuesday and has several excellent photos showing the not-so-excellent snow coverage, including the photo below of the surface hoar that is appearing on sun-sheltered slopes.

I encourage you to read a few essays from Drew - they are well worth your time!

Additional Info

Clear, cold conditions can be tough on the snowpack, and high pressure only makes things worse. The strong temperature and vapor pressure gradient transforms new snow crystals into sharp, angular, faceted grains. This is especially noticeable on shady aspects, where the snow feels almost like skiing or riding through sugar. But today’s snow surface will soon become tomorrow’s weak layer—our next Persistent Weak Layer. Read and watch more on the faceting process.
