Avoid steeper solar slopes if wet surface snow becomes deeper during the afternoon hours. A small avalanche can have significant consequences near cliffs, trees, or terrain traps such as gulleys.

Forecast for Tuesday:

Significant afternoon warming and and partly cloudy skies will revive the possibility of loose wet avalanches on Tuesday. These avalanches will take longer than usual to form due to the thickness of the surface crust in the Mt. Hood region. However, as the daytime temperatures warm, avoid steeper solar slopes where wet, slushy snow becomes deeper than a few inches.

Avalanche Summary:

Cooling from Sunday afternoon through Monday refroze the top 10-12" of wet surface snow into a firm crust.

Moderate to strong W-NW winds were seen over the weekend at Mt. Hood, but due to continued mild conditions, there is no snow available for transport in the above treeline band (NWAC's forecast does not apply above 7000-8000 feet). The mild and at times wet weather created wet snow conditions well into the above treeline terrain in the Mt Hood area. 

The upper snowpack consist of a mix a thick crust at the surface, wet snow, old crusts, and well consolidated storm snow. 


Mt. Hood Meadows pro patrol reported that wind kept the snow firm except at the lowest elevations receiving solar heating. Runnels were in the terrain up to 7300'.

Mt. Hood Meadows pro patrol reported that Friday's widespread wet loose avalanche activity had become more stubborn and isolated near and below treeline by Saturday.  The wet upper snowpack was still quite unconsolidated with the most recent 1/18 crust breaking down due to the sustained mild wet weather. Winds were strong near and above treeline but no snow was available for transport in area.
