UP TO 2 FEET OF NEW SNOW COMBINED WITH STRONG WINDS HAS OVERLOADED BURIED

LAYERS OF VERY WEAK SNOW NEAR THE GROUND, CREATING LARGE AND VERY

CURRENT CONDITIONS

Very Cold Temperatures are the morning weather headline. 3 Degrees F in Moab, -5 Degrees F at the Geyser Pass Snotel and -12 degrees F on Pre-Laurel Peak. Bundle up if you go out today and check your partners for frostbite. There should be some fine powder skiing and riding in the mountains of SE Utah, but be careful of thin ground cover and continuing avalanche danger. It goes without saying that snow conditions in SE Utah will be improving. Right now the problem will be access, followed by safety once access is gained. Be careful out there and stay off of, and out from under, slopes steeper than 30 degrees.

The San Juan County Road Dept. Opened up access to the East side of the La Sals via the Dark canyon trailhead yesterday and the road foreman says they'll get to the Geyser Pass road and lot today. If you get up there before the plows, 4WD and Chains are recommended. We'll be running them this morning.

SNOW TOTALS SO FAR:

7-8 inches of new snow reported in Moab. More in Castle Valley and Locations in Spanish Valley.

14" snow @ 9800' in the La Sals, 1.6" h2o

27" snow @ 8600' in the Abajos, 3.0" h2o (!)


RECENT ACTIVITY

None reported or observed. Yet. Expect things to get wild above treeline. Hopefully we'll have visibility today. There has been a lot of avalanche activity in the San Juans, both natural and with control work.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 48 hours.

Click here to see the newly revised North American Avalanche Danger Scale.

With 1-2 (or more!) feet of new, wind driven snow falling on a weak Faceted Grain older snowpack, we can still expect to find a HIGH Avalanche Danger above treeline on East, Northeast, and North facing slopes in the mountains of SE Utah. The danger will be more severe on, but not limited to, slopes above treeline. Slopes below treeline will have varying degrees of avalanche danger depending on the amount of snow coverage before this last storm. Natural and Human triggered avalanches are likely. Travel in avalanche terrain is not recommended.
