Turnagain Pass Avalanche Forecast

Our primary concern remains in the higher elevation zones, but poor visibility makes travel in those areas difficult.  Stormy weather has been ongoing for several days now, and is expected to continue for several more.  Storm snow and wind combined with warm temperatures are increasing the avalanche potential across the region.

Yesterday we were somewhat surprised to find softer conditions below treeline where wind has not been affecting the surface.  Above treeline is getting raked clean by the wind, resulting in challenging snow conditions.  Fresh snow is filling in slowly from the last few days.  

With 5-10 inches of snow in the last 24 hours, we expect an elevated and steady danger rating to continue today.  Wind slabs should be expected above treeline.  The East wind through the pass will be loading West facing slopes and cross loading North and South terrain features.  

We continue to find unstable test results in the old November and early December snow.  These layers are no longer easy to trigger, but given the right set of circumstances it could result in large avalanches.  

Check our observations page for an extensive list of photos and tests on these weak layers.

Don’t expect to experience collapsing or see shooting cracks on the deep layers any more.  These problems are more likely to be quiet and unobtrusive until they awaken in a big way.  With both storm layer avalanche problems and persistent slab problems, steep terrain should be avoided until the current storm cycle passes and the snowpack has at least a day to adjust.
