Mt Hood

Small natural or human-triggered wet loose avalanches are possible on steep and sunny slopes as the freezing level rises Tuesday. Choose lower angle or shadier slopes where you see rollerballs or a wet snow surface.

A few inches of recent snow sits on top of a melt-freeze crust from last week. As the sun comes out and temps start to rise, expect that small loose wet avalanches will be possible on steep slopes, especially those receiving direct sunshine. A wet snow surface and roller balls in the snow are the first sign that you could trigger a loose wet avalanche. Choose lower angle or more shaded terrain if you see these signs.

Wet snow avalanches that begin small will pick up steam on larger steep sunny slopes.  Take care near terrain traps such as cliffs and creeks, even small wet loose avalanches can knock you off your feet. 

At upper elevations, small wind slabs may linger near ridge crests and below cornices. Steer around these start zones to avoid kicking off a wind slab.

The last major storm event ended on February 27th with drier conditions interspersed with light snowfall events through the beginning of March.  In the upper snowpack, you can still find a distinct freezing rain crust buried on 2/22.  This layer was the last interface that larger avalanches released down to in the Mt Hood area towards the end of February and the first few days of March.  

During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources.  Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
