The swath of good powder is shrinking daily under the high March sun. But there is soft settled powder in a narrow band on northerly facing, upper elevation slopes, encircled by supportable and breakable crusts in the morning, which soften to damp and wet snow later in the day.
With warming temperatures and
lots of sun, I expect widespread wet snow sluffs today on steep east through south

exposed slopes heat up, expect roller balls, followed by loose wet sluffs and

Along the upper elevation peaks and ridges, a few shallow new drifts will have developed from current winds. These, plus a few isolated old drifts from Wednesday, may be sensitive to the weight of a person on steep slopes.
Bottom Line (SLC,
This morning, the avalanche danger is generally LOW. With daytime heating, the danger of wet sluffs and wet slabs will rise to MODERATE, and possibly CONSIDERABLE, on and below steep sun exposed slopes. There is the continuing MODERATE danger of deeper avalanches breaking into old layers of faceted snow on steep slopes above about 9,500 especially on northerly through easterly facing slopes. This danger may increase with warming.
High pressure will dominate the weather through Monday. Clear, sunny skies today, with highs in the low to mid 40s at 8,000 and near 30 at 10,000. Winds will be from the northwest, in the 10 to 20 mph range this morning, then decrease this afternoon. Lows tonight will be in the mid 20s in the valley bottoms where the cold air pools, but free air temperatures will be above freezing at 10,000. Monday and Tuesday will be even warmer, with breezy southwest winds. Then the weather will become unsettled, with cooler temperatures and periods of snow, Wednesday through next weekend.
