Highlights

You are unlikely to trigger an avalanche on slopes with firm, wind-affected snow. You could find areas of unstable snow in steep, wind-protected areas near cliffs and in narrow gullies. Watch out for steep slopes above 3000 feet where the snow becomes softer. Traveling on the firm snow today will help to avoid the avalanche hazard.

    In steep, wind-protected areas, you may find small areas of softer wind slab that rests on top of the hard old snow surface. Though triggering an avalanche today is unlikely, approach these areas of softer snow with caution before deciding to travel across them. The most likely places to find this hazard are on steep east-facing, and southeast-facing slopes between 3000 and 5000 feet in elevation near terrain features that provide shelter from the wind, such as cliff bands, steep rollovers, and tight gullies.

    Remember that even a small avalanche in steep terrain can have serious consequences in areas with obstacles or terrain traps below.

Avalanche Discussion

Low avalanche danger does not mean no avalanche danger. All of your standard safety protocols still apply. Continue to carry rescue gear, travel one at a time through avalanche terrain, and watch for signs of instability. Remember that small avalanches can have bad outcomes in steep consequential terrain. Before committing to skiing a slope, think about where an avalanche could carry you. Could you get pushed over cliffs or through trees? Slopes with these terrain traps are inherently more dangerous than open slopes with a clean runout.

Observations from yesterday ( One, Two) confirmed the unlikely event of triggering an avalanche in a snowpack that is largely firm, wind affected, and unreactive. Digging down into the snow, it's not hard to find interesting layers of weak snow - however these layers have proved to be unreactive and lack the ability to propagate, especially when paired with the stiff, wind-hardened snow surface that is common across steep avalanche terrain. 

It's worth keeping an eye out for the unlikely chance of wind loading beginning in the afternoon. Any loose snow that exists on windward aspects could have the ability to be picked up and moved to east and south aspects late in the day. Though unlikely, blowing snow at the ridgelines is an obvious warning sign that new slabs could be forming.
