Highlights

Dangerous avalanche conditions are expected at mid and upper elevations Sunday.  Stay off of steep wind loaded slopes to avoid triggering a slab avalanche.  You can even trigger a small wind slab on open slopes below treeline.

    The snow forecast has increased through Sunday morning. Paired with strong to extreme NW winds, we have a clear recipe for new , sensitive and large wind slabs at all elevation bands on Sunday.  Stay off of steep wind loaded slopes.  Extreme winds may form fresh slabs further downslope than usual.  N-NW winds can also cause unusual loading patterns, so don't assume the "usual" windward slopes are safe.  

    With winds this strong, you'll find wind affected snow below treeline too.  You may be able to trigger small wind slabs on open slopes at lower elevations.  Watch for shooting cracks and new avalanches as signs that it's time to step back to simpler and lower angled terrain.  

    Some ridgelines will be scoured to rocks or perhaps the 1/14 crust.  All of the new snow will be blown onto slopes below.

Avalanche Discussion

A storm will bring some new snow and a lot of wind to the Mt Hood area through Sunday morning.  While it's been relatively quiet as of late avalanche-wise, if you're out in the backcountry on Sunday, be prepared to think about matching your travel choices with the conditions. Surface hoar was observed in some locations prior to this storm, however, the intensity of the winds with this system means this weak grain layer is unlikely to survive in many places.  That said, there's always lots of variation through different terrain so make sure to stop and make frequent observations.  And of course, connect with us and your backcountry community by submitting an observation.
