South of I-80, it will be a day of increasing avalanche danger with snow and wind in the forecast. North of I-80, the avalanche danger is Considerable, and backcountry travelers need to be conservative.
The strong overnight winds have produced another batch of pockety hard wind drifts sitting on weak, sugary snow. While strongest across the highest ridges, the winds have also been significant at both the mid and lower elevations, so the new wind drifts will be more wide spread this morning, both along the ridgelines and down in open bowls, around sub ridges, and at breakovers. The stubborn hard slabs tend to break above you, and will soon be hidden beneath new snow. In addition, as the snow piles up in your area, new soft wind drifts will form and be sensitive on steep slopes.
The new snow is landing on a variety of old snow surfaces east, south and west facing slopes are a mix of rough and smooth hard crusts and wind slabs, while there are widespread areas of weak surface facets in addition to wind slabs on the shady, northerly facing slopes. The new snow will bond poorly to most of these old snow surfaces. Of most concern are the shady slopes, where it may become possible to trigger slides from a distance later today or tomorrow. So be very careful of what slope you are connected to, and avoid travel below and adjacent to steep slopes as the snow piles up.
Today will be a day of rising avalanche danger. The avalanche danger is MODERATE this morning on steep slopes with fresh or old drifts of wind blown snow. As the snow accumulates this afternoon, the danger will become MODERATE on all slopes steeper than about 35 degrees.
The avalanche danger is CONSIDERABLE on steep slopes with recent drifts of wind blown snow. Natural avalanches are possible and human triggered avalanche probable. Other steep slopes have a MODERATE danger.
