Forecast for the Skyline Area Mountains

DANGEROUS AVALANCHE CONDITIONS EXIST!!
The avalanche danger is rated at CONSIDERABLE today. Human triggered avalanches are likely on steep slopes on many aspects in the mid and upper elevations.
Your only defense is to avoid avalanche terrain. Stay off slopes steeper than 30˚ and make sure there are not steep slopes above you. These avalanches can be triggered from a distance.

Special Announcements
Avalanche Awareness Week continues!
Stop by Big Pine Sports in Fairview or Snow Big Deal in Mt Pleasant to get free batteries for your avalanche beacons and get registered for a drawing for free avalanche gear.
Weather and Snow
Current Conditions: The Manti Skyline picked up about 4 to 5 inches of new snow in the last 24 hours. Total snow depths in the upper elevations are averaging around 3 feet. Temperatures are in the teens and westerly wind has increased with moderate speeds along the higher terrain.
Mountain Weather: We should see skies clearing later this morning. High temperatures will get into the low 20s. Southwest wind will be light to moderate in speed. We should see another small shot of snow Friday into Saturday but only an inch or two is expected. Another storm will move in early next week that should bring a better amount of snow. The weather pattern remains active with numerous storms over the next few weeks.
Recent Avalanches
I received a second hand report of a small snowmobile triggered avalanche in Ephraim Canyon on Wednesday. This is not surprising given that we have a buried Persistent Weak Layer of loose sugary snow. We will continue to see avalanches breaking into this layer for a while.

Description
A Persistent Weak Layer of sugary facets that formed in mid November continues to demonstrate that our snowpack structure is unstable and dangerous. The snowmobile triggered avalanche described above is the most obvious clue. During fieldwork on Wednesday my partner and I continued to find signs of that the Persistent Weak Layer is unstable. This layer is going to continue to cause problems for a while still. Continue to stay off slopes steeper than 30˚ and make sure there is nothing steep above you.
