Good Morning. This is Evelyn Lees with the
Our wonderful return to winter continues, with cold temperatures preserving the delightful dry snow on shady slopes. This morning, light snow is falling once again in the mountains, and most areas picked up an inch or two of snow in the last 24 hours. Temperatures are near 20 at 7,000’ and in the mid teens at 10,000’. Winds are from the southeast, in the 10 to 20 mph range, with gusts 25 to 30.
This week’s snow has settled

Yesterday, the snow was mostly stable, and the only activity reported was loose snow sluffs triggered with slope cuts on steep slopes - those approaching 40 degrees or so. While the sluffs were generally narrow, a few were running long distances on the old hard, icy surface.
Today, the increasing winds will be creating sensitive drifts of wind blown snow, so it will be possible to trigger a few wind slabs in addition to the sluffs. Overnight, the winds have picked up just enough to start to drift the snow. The new sensitive wind drifts will be along the highest ridges, mostly on north through east aspects. This morning, I expect these new drifts to be shallow and pockety. If the winds increase today as predicted, the drifts will become more widespread and deeper this afternoon. New snow instabilities tend to break at your feet instead of above you. A good defensive technique is to do several good slope cuts across any steep slope before skiing or boarding it, especially those with wind drifts.
Bottom Line (SLC,
Today, the avalanche danger is mostly LOW. But there is a MODERATE danger of triggering loose snow sluffs and fresh wind drifts on any slope approaching 40 degrees or steeper. The areas of sensitive wind drifts will become more widespread this afternoon as winds increase and snow cotinues.

Tom Kimbrough is retiring, and will issue his last forecast tomorrow. We are extremely sorry to see him go, and I am hoping for a few guest appearances next season. Bruce has posted a retrospective of his life and career on the web in an attempt to do justice to his 40 years spent in the mountains.
