Kernpunkte

Avalanches in wet snow will be likely at lower elevations, especially around the Santiam Pass (5,000'). At mid- and upper-elevations, the avalanche danger will increase during the day on Sunday as the snowpack becomes saturated with rain. If you're sinking into slushy snow, move to lower angle terrain. Avoid gullies, cliffs, tight trees, and other terrain features that could make the consequences of an avalanche worse.

    Wet loose avalanches will be most likely at lower elevations, where overnight temperatures around 40 Fahrenheit be too warm for the snowpack to get a solid refreeze. This, combined with a few inches of rain on Sunday, will cause the snow surface to lose cohesion. Watch for roller balls and pinwheels on steep slopes as early indicators of wet snow instability. Monitor how deep your feet sink into rain saturated snow. If you start sinking in past your ankles, avoid terrain that's steeper than 30 degrees. 

    Depending on how much rain falls, wet slab avalanches and cornice failure could be possible. It will be best to avoid cornices on Sunday. If you're sinking deep into the snow (such as to your boot tops), you should be thinking about wet slab potential. Remember that wet loose avalanches can carry a lot of weight as they entrain snow and could trigger a wet slab. Heavy wet snow can also push you into terrain traps like cliffs or rocks, gullies, and trees. 

    With rain levels reaching 9,000' this evening, wet loose avalanches will be possible at near treeline elevations, but colder air temps and strong to extreme winds will keep the snow surface cooler. The alpine could see a mix of rain and snow on Sunday, but minimal accumulation, if any. With winds gusting to 60 mph on Sunday, I would not recommend going up high. If you do, be sure to bring two waterproof jackets and at least three pairs of gloves.
