| Advisory: Skyline Area Mountains | Issued by Craig Gordon for Friday - February 28, 2014 - 5:28am |
|---|
|
bottom line A CONSIDERABLE avalanche danger exists and human triggered avalanches are probable on steep wind drifted slopes, especially those facing the north half of the compass.
|
 |
avalanche watch An AVALANCHE WATCH has been issued for the mountains of northern Utah and that includes the Manti-Skyline. Both natural and human triggered avalanches are likely on upper elevation, wind drifted slopes. Dangerous avalanche conditions will materialize this weekend as a powerful storm is expected to slam into the region tonight with strong winds and heavy snow. |
 |
current conditions The Skyline picked up 6" of new snow yesterday and west-southwest winds bumped up in the afternoon, gusting to 40 mph along the high ridges. Temperatures are in the mid to upper 20's. |
 |
recent activity No new avalanches have been reported since We continue to get views into different areas which unveil the very impressive avalanche cycle that occurred during the big storm two weeks ago. There were many large slides that snapped trees as well as numerous in odd locations such as thicker trees and lower elevations. Here is the avalanche list that hardly covers a sliver of the terrain that avalanched over the last few weeks:

description
Strong winds and heavy snow will stress weak layers buried deep in the snowpack. As the weekend storm materializes avalanches have the possibility to break to the ground. Steep, upper elevation, wind drifted slopes facing the north half of the compass should be avoided. There are more thoughts, photos and videos on the deep slab issue HERE. Darce Trotter also submitted some thoughts HERE |

description
Fresh drifts will be sensitive to the additional weight of a rider today. These should be mostly manageable in depth and width and breaking at or below our skis, board, or sled. However, in steep, rocky terrain a fresh drift has the possibility to break into weaker layers of snow, buried deeper in the snowpack, creating a slide that gets quickly out of hand. As always, look for and avoid any fat, rounded pillow of snow, especially if it sounds hollow like a drum. |
 |
weather A moist Pacific storm system moves through the region beginning today, with precipitation likely beginning this evening. West and southwest winds increase significantly for the latter half of today, and remain strong into Saturday morning. The region should fair pretty well with periods of snow through Saturday night. |

last week's close call when a snowmobiler triggered a very large slide near the Skyline Summit. (photo- Cade Beck) The rider tirggered the slide at the apex of his high mark and was able to ride it most of the way before getting thrown but not buried or injured.
