In sintesi

Areas of MODERATE danger exist in the upper elevations where sensitive wind drifts up to a foot deep are possible. Some of these drifts may be triggered at a distance. Loose snow sluffing is also expected in the steepest terrain. The danger is LOW at the low and mid elevations.

Four to six inches of new snow can easily be blown into wind drifts eight to twelve inches thick. These drifts are being blown onto a variety of slick or weak snow surfaces (note Chris Brown observation and photo below of fairly widespread surface hoar) and may be surprisingly sensitive to the weight of a skier or rider. They may also be triggered from a distance. Given the highly variable pre-existing snow surfaces, it'll be wise to anticipate sensitive conditions and foolish to extrapolate conditions from slope to slope, even slopes on similar aspects. Collapsing and shooting cracks are common signs of instability.

Note that the drifts will be primarily limited to the higher elevations but any terrain with fresh drifts of wind blown snow should be treated with caution and/or avoided.

Sluffing of the new snow is expected on all aspects in the steepest terrain this morning. In confined and sustained terrain features, even 4-6" of new can pile up deeply, especially in terrain traps.

Snow and Weather

Snowfall began a little before midnight and we're up to 2-4" (0.2-0.4" SWE) in the central Wasatch. We may squeeze another inch or two out of this system yet.

Temperatures are in the single digits and low teens. Winds are light from the northwest except along the highest elevations where we're seeing hourly averages of 20-30mph with gusts to 45.

As the storm moves through, winds will shift north and then northeast and we'll see cool bitter winds of 15-20mph from those directions. Temps will be in the upper teens and low 20s. Clouds will thin and we'll see mostly and then partly cloudy skies by the afternoon. High pressure builds back in for the weekend with a weak storm slated for Monday night. I'm not seeing much on the horizon until the turn of the month. We'll see.

Skiing and riding conditions have been a little rugged of late and these few inches will do wonders for those with their cups half full. Low angle protected* slopes are recommended.
