Regions: Mt Hood.

The avalanche danger is low. However, non-avalanche terrain hazards are present due to the thin snowpack. Also, be prepared to self-arrest if traversing steep and icy slopes.  

Detailed Forecast

Light rain and snow showers should end by early Monday, becoming partly cloudy later Monday along with light winds.This will not change the overall low avalanche danger and there are no highlighted avalanche problems expected in the Mt. Hood area. 

As a general backcountry travel safety note, watch for terrain hazards (exposed rocks, trees, streams, etc) at lower elevations and on wind scoured aspects. On non-solar aspects with a slick and supportable crust, take extra caution when traversing steep slopes and be prepared to self-arrest if necessary.  

Snowpack Discussion

Mild temperatures and a few light rain or snow showers were received Saturday, followed by a little cooling and periods of light showers Sunday depositing up to a few inches of new snow by Sunday afternoon. This has not appreciably changed the overall stable snowpack and current low danger.

The Mt. Hood area received light snow a week ago Sunday, but 2.5 - 4.5 inches of precipitation fell through last Monday, the majority of which fell as rain.  

Dry and unseasonably warm weather followed the rain last week, through Friday. This has allowed the snowpack to drain, consolidate and generally reset the upper or even entire snowpack. Melt-freeze crusts of varying thicknesses have formed during the clear nights last week with generally only southerly aspects softening. On some windward or southerly aspects, there is little snow cover. 

The Mt Hood Meadows patrol reported a breakable crust near tree-line and supportable crust above treeline early Friday morning.
