In sintesi

A CONSIDERABLE avalanche danger exists on steep northwest to east facing slopes at the mid and upper elevations. Human triggered avalanches 1-3' deep and up to 200' wide are likely...and may be triggered at a distance.

A MODERATE avalanche danger exists on all southwest-south-southeast facing slopes and in the low elevation bands.

Great skiing can be had on low angle terrain not attached to steeper slopes.

The mid-November drought created a very weak layer of facets and patches of buried surface hoar on all aspects and elevations throughout the Wasatch Range. Avalanches have been triggered at this weak interface as well as collapsing and whoomphing. These signs are clear red flags that avalanches could occur today.

Northwest through east facing aspects harbor a layer of weak faceted snow and have also seen the most wind loading and this is why the danger remains considerable on these aspects. On southwest-south-southeast aspects the danger remains moderate because there is less snow on top of the weak faceted layer and there is a lower likelihood of triggering an avalanche on these aspects. Mark Staples explains more about southerly slopes in the video below.

Additional Info

MOST ACCIDENTS AND FATALITIES OCCUR DURING A CONSIDERABLE AVALANCHE DANGER THAT INVOLVES A PERSISTENT WEAK LAYER.

A word to the wise: Don't get fooled.

As avalanches become more stubborn and cracking and cracking become less commonplace, there can be a tendency to believe that conditions are improving faster than they are.

The GOOD NEWS is that riding conditions are 5 STAR on shady low angle slopes. Choose low angle terrain with nothing steep above you.
