Forecast for the Salt Lake Area Mountains
Wednesday, December 20, 2017
It is a day of rising avalanche danger as the wind drifts (wind slabs) grow. The avalanche danger is MODERATE today - human triggered wind slab avalanches are possible on mid and upper elevation slopes facing northwest through southeast, where the snow drifts are sitting on old snow. Evaluate snow and terrain carefully, identify and avoid all wind drifts on steep slopes. The avalanche danger will increase and become more widespread when the snow arrives late this afternoon.
Out of the wind-affected terrain, loose snow sluffs and shallow soft slabs may be triggered tonight if we get more than about 6” to 9” of snow.
