Mt Hood

Generally safe avalanche conditions exist. Light rain at lower elevations may create the potential for wet avalanches where snow has not consolidated. Use caution around high elevation, steep lee slopes where wind deposited snow may accumulate. 

Mild weather continues and stable avalanche conditions are the norm. A strong inversion is still in place and temperatures at lower elevations and in valleys have stayed cool while spring-like conditions have been developing at higher elevations. Light rain and snow is expected Tuesday night. Pockets of wind slab may develop above treeline, on isolated lee slopes. Look for and avoid steep start zones where the wind has recently deposited snow. Favor slopes under 35 degrees where you see evidence of freshly blown snow. Don't overlook the possibility of a loose wet avalanche where rain falls on preserved fresh snow. Look for evidence like rollerballs on the snow surface to clue you into avoiding slopes with direct sunshine if you see evidence of a weakening snow surface.

Previous Discussion: Roughly 3" of snow arrived early Sunday morning along with a burst of westerly winds.  Ski patrol reported sensitive slabs in the AM 12+ inches deep on E-NE aspects near and above treeline and at least one public traveler reported triggering a small (D1) wind slab above treeline.  As conditions warmed Sunday and showers tapered off,  snow surfaces moistened.  After a fast start to winter in November, avalanche activity over the last week has been fairly quiet as we wait for more active and cooler weather to return. 

Surface conditions and snow depths vary greatly by elevation and position on the mountain.  At mid-elevations on the south side of Mt Hood, snow depths average around 40-50". Conversely the NE side remains shallow with 20-30" common near treeline.  In areas with low snow cover, early season conditions exist. It's a long season so use care to avoid stumps, rocks, open creeks, and other early-season hazards. 

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.
