This morning the old snow surface is covered by some very nice and low density new snow and reports from the backcountry indicate that the turning conditions are dreamy.
Yesterday was a classic
Today it will still be easy to trigger sluff and some soft slab avalanches on all aspects, and I expect to see natural avalanche activity on the steep sun exposed slopes. Most of these avalanches will limited to the loose surface snow, but remember we still have several buried weak layers in the snowpack. Although loose snow avalanche are most dangerous in areas where they could push you off a cliff or into a gulley, these slides could become large enough to trigger a more dangerous deep slab avalanche. The surface snow will be quite active on sun exposed aspects, so the danger will rise as the day heats up. Avalanche breaking into the deeper weak layers are possible on all aspects but most likely on steep northwest through east facing terrain that has a thin weak snowpack or that has avalanched previously in the season.
Bottom Line (SLC,
Today there is a MODERATE danger of triggering a loose snow avalanche on any slope steeper than about 35 degrees. On sun exposed slopes the danger may rise to CONSIDERABLE with day time heating. In the afternoon, traveling under steep sun exposed slopes is not advised. There is also a MODERATE danger of triggering a deep slab avalanche on slopes steeper than about 35 degrees and above 9,000’. Today this danger is present on all aspects, but deep slab avalanche are most likely on northwest, north, northeast, and east facing slopes.
Note: the western Uinta Mountains have a CONSIDERABLE danger
