In sintesi

Generally safe avalanche conditions today for the Blue mountains of Northeast Oregon. Temperatures today are forecasted to be well above freezing. Wet loose avalanches on terrain steeper than 35 degrees this afternoon is the main potential problem. The solution is to be off slopes steeper than 35 degrees when the snow surface starts showing signs of instability.

    Temperatures this afternoon are forecasted to rise well above freezing in the Blues today. Above freezing temperatures cause cornices to weaken. These weakened cornices can easily fail under the weight of a human. If you find yourself traveling at ridgelines today, stay well back from slope edges unless you are certain that the slope edge is not a cornice.

    Even though temperatures were at or below freezing last night, I think wet loose avalanche activity is a possibility today because temperatures are forecasted to climb into the mid forties by this afternoon. If you plan to recreate on slopes steeper than 35 degrees today in the Blue mountains, it is advised you get on the snow early and get off the steep slopes at the first sign of snow surface instability. Sinking into the snow up to your boot tops is a sure fire sign that the snow could be getting weak and that it is time to move to lower angle slopes less than 35 degrees. Also, the observance of roller balls and pinwheels on the snow surface are other warning signs that the snow is becoming unstable and that it is time to move onto low angle slopes less than 35 degrees.
