Forecast for the Moab Area Mountains

Eric Trenbeath
Issued by Eric Trenbeath on
Saturday morning, November 21, 2020
I'm back in the office and in the field for the 2020-2021 winter season. For the time being, I'll be monitoring conditions and posting periodic reports. I'll begin daily detailed avalanche forecasts when there is enough snow to ride which also means there will be enough snow to slide! Snow cover is currently limited to northerly facing, shady slopes above about 9000' and depths range from a few inches to 18". In short, there is just enough snow on the ground to begin forming a problematic weak layer of, sugary, faceted snow at the base of the snowpack. This doesn't bode well for future stability.

Additional Information
Here is a recap of the season snow history.
A powerful storm on Oct 25 brought the first significant snow to the mountains with snow levels dropping to the valley floor. Up to a foot of snow graced the high country. Aerial observer Chris Benson took these photos of a plastered mountain range, and Chris Bolos got the first turns of the season.

Warm temperatures over the next couple of weeks diminished much of the early season snow. This alleviated some of our fears over a widespread, persistent weak layer, but some areas of old snow still remain. This will make things a bit tricky as we move forward and we will have to suspect weak, faceted snow at the base until we prove otherwise. Likely areas of concern are on sheltered, northerly aspects right around treeline, and in areas where the wind has deposited greater amounts of snow.

A storm on Nov 9-10 brought another 6"-10" to the mountains. With the dry period that followed, this most recent snow will likely become a weak layer of loose, sugary facets at the base of the snowpack. We'll want to pay attention to this before the next snow comes hopefully later this week.
