The Bottom Line

You could trigger avalanches on steep slopes where you find 3" or more of new snow, especially where the wind forms fresh drifts. Watch for actively blowing snow near ridges and at the base of cliffs as a sign of the danger. Steer around fresh pillows of drifted snow on slopes over 35 degrees.

The East North zone will receive just enough new snow and wind to build shallow slabs of snow by Thursday afternoon. Watch for small drifts on leeward slopes, immediately below ridges and cliffs, or in cross-loaded gullies. Steer around convex roll-overs and shallow pillows of drifted snow on steep slopes.

Watch for blowing snow to indicate where you can trigger avalanches. The East North zone could receive 3-4" of snow on Wednesday night into Thursday. Westerly winds could gust up to 30mph. 

Forecast Discussion

In addition to wind slab avalanches, be alert to triggering small loose dry avalanches in wind-sheltered terrain. Both the new snow falling on old weak snow surfaces and a chance for sun could be contributing factors. If you see the sun shining on slopes that have accumulated new snow, you could encounter some small loose avalanches. Cold temperatures have weakened the old snow, especially on shady northerly aspects at middle and upper elevations. As the new snow accumulates, avalanches could be easy to trigger. 

On the 29th, a skier triggered a small wind slab avalanche on Silverstar Mountain at 7,200ft on a northeast aspect. The new snow will fall on a variety of surfaces.  In sheltered areas at mid and upper elevations, there's 6-10" of settled storm snow above the most recent crust.  In wind-exposed locations, the recent snow is heavily textured and drifted. On sunny slopes, slick crusts are on, or just below, the surface.

Snow cover is thin on southerly slopes and at low elevations. Be aware of exposed rocks and open creeks. WSDOT has begun plowing operations on Hwy 20 between Silver Star trailhead and Newhalem. The road will be closed to all traffic Monday through Thursday while workers and machinery are operating.
