The avalanche danger is LOW and avalanches are unlikely. The main hazard now isn't avalanches, it's hitting rocks and other obstacles or sliding on a hard ice crust found on most slopes.

If you missed the 13th Annual Utah Snow and Avalanche Workshop, the recordings are available for purchase from the UAC Store.
Weather and Snow
This morning temperatures are in the mid to low teens F although some warmer air raised temperatures at upper elevations into the mid 20s F. Ridgetop winds are blowing 10-15 mph gusting to 20 mph from the SW.
Today will start clear and sunny with temperatures warming into the upper 20s and low 30s F. Winds will increase some this afternoon and bring clouds as a cold front approaches.
Tonight, temperatures will drop back into the teens F. Some snow will fall late tonight into tomorrow morning bringing 2-4 inches of low density snow although a few places could get 4-6 inches.
Most slopes have a firm crust near the snow surface underneath 1-3 inches of snow that fell Monday night.
Recent Avalanches
No new avalanches were reported from the backcountry yesterday.

Description
It will be very hard to trigger an avalanche today. The main hazard is hitting rocks or other obstacles because the snowpack is thin. Above 9000 feet snow depths range from 11-21 inches.
This thin snow is mainly an avalanche problem for the future. Why? Clear, cold nights are weakening and faceting this fledgling snowpack. Read more below.
Additional Information
Forecaster's Corner:
With clear skies and cold temperatures, the snow is becoming weak and faceted (see Mark White video below). In the short term, this means you can buy a soft turn here or there, but in the long term it becomes a very real sliding surface for future avalanches whenever we see the next significant storms. At this point, the snow surfaces are quite variable, but it will be something to keep an eye on in the coming days (or weeks).
For the layperson, remember that ingredients for an avalanche often involve strong cohesive snow (the slab) sitting above weak, sugary snow (the weak layer). Currently, the weak layer is forming and what's lacking is the slab. Sugary faceted (angular) snow below.
