Recreational Observation

Open area within forest, deposition zone, 34-38 degrees, wind-protected.

March 9, 2016, noon PST

Weather: Beginning of storm, snowing, winds to 15 MPH

Snowpack: Fluffy new snow, 2-3 inches accumulated on refrozen supportable crust. Weak bond. The entire slope runs to the crust while skiing. Similar areas out of or having less wind effect, such as particular aspect above the Rockslide above groomed snowmobile route 5 miles from Blewett Sno Park and areas of similar aspect in the Wenatchee Mountains may have this extremely weak bond of the new snow to the supporting refrozen surface. New snow accumulations may sluff or if accumulated or slab may natural avalanche or would be sensitive to release. Of note, other aspects that were affected by heavy winds are packed, firm, chalky shallow new snow accumulations on the supportable crust, and may not produce the above mentioned instability. While traveling be aware of aspect changes that may result in one traveling from an area of relative stability in a short distance to an area as described above with likely instability of the snow above the refrozen supporting crust.

Area Description: Diamond Head, NE facing, 5700' elev.

Avalanches: While skiing 700 vert. ft., the areas of the slope with angle of 34 to 38 degrees released the 2-3 inch new snow layer as I skied.
