December 11, 2006 - 6:19 am The avalanche danger is MODERATE for loose and storm snow avalanches at the mid upper areas of the Salt Lake and Park City mountains. Along the periphery where storm totals were less than 5, the danger remains generally LOW.

The overnight and expected water weights through the week probably wont be enough to get things going until the weekend. As the steeper slopes on all aspects will sluff easily today, watch for how much snow they entrain and move across the fall line from sub-ridge to sub-ridge to avoid the loose snow. If we get any sun this afternoon, the sunnier aspects may remain active with this issue. Only the highest, most exposed ridgelines will likely have some very soft, sensitive wind drifts. A cornice drop or slope cut moving into safe terrain should be an effective tool for these.
The good news is that it will be excellent in the backcountry, if not a little scratchy underneath. If we get a bit more snow or wind than expected this morning before it clears out, watch for cracking and collapsing in the weaker snowpack areas and anticipate that buried weak layers of this nature allow avalanches to be triggered from a distance.
None The Cottonwoods picked up about 8-10 of cold smoke overnight, with the Park City, Ogden, and Provo mountains receiving 3-5. Densities cashed in at 6-7%, rolling in right side up as temperatures dropped during the storm. After the cold front passed through, the winds shifted northwest and remained on good behavior blowing just 10-15mph. A few of the highest anemometers showing an hour or two in the 20mph range. Temps are now in the mid teens at most locations.
