Description: 

The snowpack is currently stable and avalanches are unlikely. However, with a couple of possible weather systems early this week, the avalanche hazard may elevate:

  • 1-3" of snow are expected Monday afternoon creating possible shallow storm slab avalanches.  
  • Moderate to strong winds first from the south/southwest, and then shifting to the northwest on Monday afternoon may create fresh, sensitive wind drifts at the mid and upper elevations.

Although any storm slabs or wind drifts will be quite shallow, even a short ride on our thin snowpack will mean a ride over rocks and stumps.

Unopened ski area terrain has a backcountry snowpack, as avalanche mitigation work has not been done. Each resort has different uphill travel policies - please abide by signage and closures and check in with the local ski patrol.

Current Conditions: 

Conditions as of 3 pm Sunday afternoon feature very mild temperatures with increasingly strong south and southwest winds. Temperatures at 10,500' are in the mid 40's F with gusts over 50 mph from the south.

A rain event to 10,000' early last week, along with very warm temperatures over the Thanksgiving holiday, have crusted most snow surfaces. Southerly aspects have largely melted off, with patches of snow clinging to southeast and southwest aspects. In the Salt Lake mountains, northerly aspects > 9000' hold about 18-24" of snow (red arrows)

 

Recent Activity: 

There have been no observations received from the Provo mountains. Recent observations from the central Wasatch include:

Little Cottonwood Canyon (Alta) (Nov 26)

Big Cottonwood Canyon (Brighton) (Nov 25)

Little Cottonwood Canyon (Alta) (Nov 23)

Little Cottonwood Canyon (Alta) (Nov 23)

 

 

Mountain Weather: 

Cloudy, windy, and mild through early Monday afternoon when we can expect a quick-hitting storm that may bring 1-3" to the provo mountainson a northwest flow. Clearing Monday night followed by cool high pressure on Tuesday. Another quick-hitter is possible for Wednesday, with a few more inches of additional snowfall. Models are hinting at something more promising for late this coming weekend. 

Bottom Line: 

The avalanche hazard is LOW. With a couple of possible small storms early this coming week, the hazard may elevate due to fresh storm snow as well as possible wind drifting.  Remember - a low avalanche hazard doesn't mean no avalanches. 

We will continue with intermittent advisories until we begin to receive more snow.

Description: 

Despite the very warm weather over the past several days, the weak, faceted snow at the bottom of our snowpack on upper elevation northwest through northeast aspects remains. This video from Thursday highlights this very weak snow:

Currently, these weaknesses are mostly dormant, and the likelihood of triggering one of these persistent slab avalanches is quite low. But persistent weaknesses will show their hand once again with new loading such as storm snow and/or wind deposited snow.
