Kernpunkte

Another day with unseasonably mild, sunny weather will maintain the possibility for small wet loose avalanches on steep sunny slopes.  These avalanches can be easily avoided by paying attention to how the snow surface changes during the day.  Don't let a small avalanche take you for a ride near a terrain trap.

    High freezing levels and above freezing temperatures will continue Sunday night and Monday at mid and high elevations,  once again softening surface crusts that formed overnight.  You're more likely to find lingering soft snow on shadier and more wind sheltered aspects.     

    Avoid similar slopes if you see small wet loose avalanches and rollerballs on very steep southerly slopes and below rocky outcrops.  Switch to lower-angle terrain or change aspects if you find yourself sinking into wet, heavy snow more than a few inches.  Since most of these avalanches will be small, exercise the most caution around terrain traps, like above cliff bands and open creeks.  We're still dealing with an early season snowpack and there are still plenty of obstacles (like exposed or barely covered rocks, stumps, etc) that could magnify the consequences of a small slide.  Continue to think about small wet loose avalanches wherever you find enough snow to slide on at lower elevations.

    Small wet loose avalanches were observed below rocky outcrops in the West South zone on Saturday.  Watch for similar activity on Mt Hood on Monday.

Avalanche Discussion

If you head into upper-elevation terrain or beyond, don't forget about the winds this past week. Most recently, some snow may have been transported by moderate winds Friday night. While the winds have calmed down, recent shallow slabs could linger on shaded aspects at the highest elevations. Take the time to evaluate the potential for slab formation by making use of small wind-loaded test slopes and by evaluating how easily the snow releases off the underlying crust.  

Early-season cornice failures could also trigger wind slabs on the slopes below, and represent a hazard in their own right.  Photos of wind slabs and wind affected snow from last week are in the gallery. 

We may be in a bit of a lull but mid-elevation snow depths are well above average for this time of year, enjoy the early season coverage and sunshine!
