Avalanche Advisory
Advisory: Skyline Area Mountains Issued by Brett Kobernik for Saturday - January 21, 2017 - 6:59am
bottom line

The avalanche danger is MODERATE in the mid and upper elevation terrain on slopes steeper than 35 degrees. Human triggered avalanches are possible. The danger may rise to CONSIDERABLE if we receive more snow than I'm anticipating. Watch for cracking during your travel and avoid bigger steep slopes if you are seeing lots of shooting cracks.
special announcement

If you sign up for AmazonSmile and designate the Utah Avalanche Center as your favorite charity, they will donate a portion of everything you spend to the UAC. It doesn't cost you a penny and we'd really appreciate the help.
current conditions

2 to 4 inches of snow fell Thursday afternoon and night. There was some riming that occurred during the day on Thursday which we noted while it was coating our glasses and goggles during the ride. You will notice a thin rime crust under the new snow. Overall, the snowpack is well consolidated and stable. At the end of the day on Friday the wind increased a bit and was starting to transport snow into drifts. We noted slight cracking in the wind drifted areas. Steve and Darce noted similar conditions on their travels which can be found HERE.

Not much snow accumulated overnight. Ridgetop wind is from the southeast in the light to moderate speed category. Temperatures are in the low 20s.

The main concern today is the potential for human triggered avalanches within the newer snow. We may see some failure around the buried rime crust from Thursday. We may also see some weakness under freshly formed wind drifts. These problems most likely will not be long lasting concerns but we will want to pay close attention during the current storm and the next storm expected on Sunday night.

As the wind shifts to the northwest mid day and increases in speed, we will probably see some fresh sensitive drifts form. Avoid areas where wind is rapidly depositing snow along the upper ridgelines.
weather

We should see snow during the day today. I'm anticipating 4 to 6 inches of snow. Ridgetop wind is going to shift to the northwest mid day and increase in speed somewhat. Temperatures will remain in the low 20s. We'll see cloudy skies on Sunday with light southerly wind and high temperatures in the mid 20s. A larger storm starts moving in late Sunday and will last into Tuesday with stronger wind. This could produce a foot of snow or so along the Manti Skyline.
