Forecast for the Moab Area Mountains

Eric Trenbeath
Issued by Eric Trenbeath for
Tuesday, December 12, 2023
There's not enough snow for off trail riding and sliding and triggering an avalanche is unlikely. On upper elevation, northerly aspects, there may be some isolated slabs of wind drifted snow overlying weak, sugary, faceted snow. These areas are extremely difficult to access at this time but if a slope looks like it has enough snow to ride, it has enough to slide. Suspect the deepest snow areas on the leeward sides of ridge crests and terrain features. Even a small avalanche triggered could take you for a very bumpy ride. We'll start providing regular forecasts when there is enough snow to get around on.

Thanks to everyone who turned out and supported events during Avalanche Awareness Week!
Weather and Snow
General Conditions
The last significant snowfall was 6" on Friday, Dec 1. 1"-3" is in the forecast today. Warm tempeartures this week have shrunk the base to 17" in Gold Basin. About a foot of snow is on the ground at the Geyser Pass winter trailhead. Season snowfall total is 29". The bottom line is that we are still a storm or two away from having enough coverage for real turning and riding off the roads. There is enough snow on the Geyser Pass Road for cross country skiing. Remember that the road is technically open until Dec 15, so if people try to drive on it, they are allowed to do so even if getting stuck is a certainty.

Description
Several inches of pre-existing snow has turned to weak, sugary facets at the base of the snowpack on northerly aspects. Time will tell how big of a problem this becomes, but we'll be keeping an eye on it. For now, it's only a concern in upper elevation, northerly facing terrain where winds have drifted slabs over top. Most of the areas where you would encounter a problem are difficult to access because of the low coverage, but if you find yourself in the upper elevations, remember that if it has enough snow to ride, it has enough snow to slide. Suspect the deepest snow areas on the leeward sides of ridge crests and terrain features. Even a small avalanche triggered could take you for a very bumpy ride.
Additional Information
It’s never too early to start thinking about avalanches. Here are a few things to consider doing:
1-Sign up for an avalanche class.
2-Take a free online avalanche course the UAC built for Know Before You Go or other courses listed on the KBYG website (Develop skills -> Online Learning).
3-Get your avalanche rescue gear ready for winter. Put fresh batteries in your transceiver and update the firmware. Inspect your shovel and probe. Get your airbag backpack ready by possibly doing a test deployment and updating the firmware if it is an electric version.
