Highlights

The avalanche conditions are generally safe.  Watch for a chance of small wet avalanches on steep sunny slopes. Keep plenty of space between you and any cornices or overhead slopes with glide cracks.

Avalanche Discussion

While avalanches are unlikely, there are some factors to keep in mind. If you find wet weak surface snow, consider moving to slopes less than 35 degrees. This may be more likely in the eastern half of the zone where daytime temperatures will be warmer than near the Cascade crest. Stay well out from under any slopes with open glide cracks or suspected rock slabs that are still covered in snow. A significant cycle of glide avalanches began on April 3rd in the neighboring Snoqualmie Pass zone.

Any recent snow accumulation has been less than 1 inch. The last major storm brought around a foot of snow at the Cascade crest on the 29th, and about half of that for areas further east like the Wenatchee Mountains. The sun has formed crusts of various thicknesses on all other aspects. Slopes that face directly north above 6,000ft may still hold dry snow. 

The lower snowpack is generally strong. The mid-January weak layer is dormant but can still be found about 2-6 feet below the surface. It shows up as weaker facets near a crust or a thick layer that's a mix of rounded facets and weak melt forms.  There have been no avalanches reported on this layer since March 1. A major warming event could produce large wet slab avalanches on this layer.
