Greg Gagne
Issued by Greg Gagne on
Friday morning, December 25, 2020
There is a CONSIDERABLE avalanche danger upper elevations on aspects facing west, north and east for triggering avalanches that are 1-2' deep and over a hundred feet wide. Avalanches may be triggered remotely and from lower-angled terrain. Avoid being on, underneath or adjacent to slopes greater than 30°in steepness on these upper elevation aspects.
On mid and upper elevation southerly aspects there is a MODERATE danger.
Low elevations have a Low danger.

read Mary Ruefle.

This Morning: Some high thin clouds and temperatures range through the 20's F. Winds are out of the south/southwest and generally light - less than 10 mph - with gusts in the 20's mph along the upper elevation ridgelines.
For Today: High thin clouds with clearing this afternoon. Temperatures will remain mild, rising slightly above freezing in most mountain locations, with lower-elevations reaching the mid 30's F. Winds will be out of the southwest and remain generally light, with an uptick this afternoon with gusts in the 20's mph at the upper elevations.
This Weekend: Increasing clouds tonight with a weak system for Saturday which may bring a few inches of light snow. Looking further ahead, chances for light snow early this coming week and then perhaps right around the New Year.
Recent Avalanches
No reports of recent avalanche activity apart from a reported catch-and-carry in Bailey Spring area adjacent to Cutler Ridge on Ben Lomond this past Sunday.

Description
There is a layer of weak faceted snow at the mid and upper elevations on aspects facing west, through north, and southeast. The photo below from Hell's Canyon illustrates this weak snow at the base of the snowpack: [Photo: Jared Allen]
UAC forecaster Nikki Champion was on Cutler Ridge yesterday and shares what she found in this video (read her excellent full observation):
Avoid slopes steeper than 30° on upper elevation aspects facing west, through north, and east. Triggering an avalanche on these slopes is likely; they may be up to 1-2' deep and over a hundred feet wide.
The good news is that low-angled slopes in non-avalanche terrain are riding quite well!
