In sintesi

There is a small chance you could encounter unstable snow on wind-loaded features high in the alpine or on steep sun-exposed slopes. Challenging, slick travel will be one of your greatest hazards. 

Problemi valanghivi

    Dimensione
    1–1.5

    Remain alert for isolated slabs of drifted snow in steep, upper-elevation terrain above 7500 ft. These may be on any aspect, thanks to variable wind directions the past few days. While most will be small, they could still ruin your day in steep, consequential terrain. Keep in mind that any triggered wind slab could easily turn into a long, sliding fall scenario with the slick surfaces we currently have in the alpine around Mt Hood. 

    Look for pockets of softer snow that appear textured, rippled and pillowy as signs of recent wind loading. You can use small test slopes or quick hand pits to help you identify how reactive this wind-drifted snow is acting. Shooting cracks, hollow-sounding snow, and snowpack collapsing are all good reasons to simplify your terrain selection.

    East winds drifted available snow into reactive 6-12 in slabs along west aspects on Monday. You may find lingering pockets on Wednesday.

Avalanche Discussion

The danger has dropped, but still keep a few things on your radar as you travel in the mountains on Wednesday:

1). Wet Loose Avalanches: We suspect most wet loose avalanches have run its main course by now, but another warm day with decreasing cloud cover could allow for the surface crust to break down in select steep terrain with sun exposure. If this does happen, look for signs of warming, weakening surfaces and consider moving to shadier slopes if rollerballs start shedding. 

2). Long, Sliding Falls &  Challenging travel: Widespread slick surfaces plague the upper slopes of Mt. Hood creating a real hazard for backcountry travelers, especially in the alpine. If you plan on traveling across steeper slopes, consider packing the crampons, ice axe, and the ability to use this gear properly. Allow yourself more time to navigate the challenging backcountry conditions.
