The issue is simple today, as the snowfall totals increases, the avalanche danger is going to increase as well. Roughly 5"-12" inches of new snow has fallen throughout the Wasatch range by 5 AM this morning, and the cold front is predicted to have multiple periods of high snowfall rates and overall high snowfall totals (20-28" of snow by Wednesday). All of this new snow is going to have a variety of excellent bed surfaces to slide on and I expect to see shallow new snow avalanches in the backcountry today.
With the generally cold temperatures, and so many supportable bed surfaces in the backcountry, I would expect to see the new snow primarily failing as fast running sluffs, but this doesn't mean that shallow soft slab avalanches are out of the picture, particularly in sheltered terrain features. Look for both types of new snow instabilities today.
The type of avalanche will come down to how quickly the new snow bonds, versus how quickly the snow is falling from the sky.
During any periods of higher rates of snowfall (greater than 1 inch per hour) avalanches will be easier to trigger. Pay attention to changing weather and increased snowfall rates. Watch for signs of instability such as cracking and sluffing. Even a small slide can have serious consequences in big, steep terrain or if you’re above cliffs.
The good news - this new snow issue should be generally simple to get a handle on how stable or unstable the snow is today. Use small test slopes to see how the new snow is behaving, take your shovel out, and perform a shovel tilt test or an extended column test to see if there is any propagation within the new snow.
