Moab Avalanche Advisory

Forecaster: Dave Medara

BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

We need more snow. We have a thin snowpack with rotten and unsupportable conditions topped off by a mix of wind and sun crusts. Expect to find a MODERATE avalanche danger in SE Utah on most slopes. Keeping POCKETS of CONSIDERABLE danger in the forecast for upper elevation alpine bowls in the La Sals on N thru NE thru NW facing slopes.

CURRENT CONDITIONS

Good skiing and riding conditions are getting harder and harder to find in the mountains of SE Utah. After a week of high pressure, Strong temperature gradients have weakened the snow on the ground leaving a combination of punchy snow and wind crust over a thin ground cover. Sunny side slopes have sun crusts on them and very little snow. This is making for some challenging and unforgiving conditions. On our tour to Gold Basin on Saturday, we found a wind swept boneyard in Tele Heaven with the best skiing found in avalanche debris from extensive slides off Tukno Mountain. The good news is that we have more snow on the way so read on for more on the weather. We have about 25 inches of snow at the Gold Basin study plot and there are 15 inches at the SNOTEL site above the Geyser Pass Trailhead. These totals put us at about 110 percent of normal snow on the ground for this time of year although It feels like less than that.

Roads to the La Sal Mountain Trailheads (east and west sides) have been cleared by the San Juan County Road Crews. Thanks Guys. The road is getting pretty slick.

LUNA volunteers groomed up and over Geyser Pass Friday. It's a bit rough as this was the first foray to the upper Nordic Trails and it will take a a couple of missions to really smooth it out. The upper Nordic loops were groomed though as was the lower Meadow loop. Enjoy.


RECENT ACTIVITY

No recent activity, cracking and collapsing still being noted in the snowpack.

The Avalanche Danger has lessened in SE Utah with a week of high pressure and lighter winds. We're keeping pockets of CONSIDERABLE Avalanche Danger rating intact for upper elevation slopes above about 11,500 feet in the La Sal Mountains as these areas are more wind loaded. Expect to find a MODERATE Avalanche Danger elsewhere in the mountains of SE Utah. Remember, MODERATE does not mean NO avalanche danger. There is still a lot of collapsing and cracking going on. The snowpack in SE Utah is very weak, which is common this early in the winter. As always, travel in the backcountry with caution.

Our weak snowpack is likely to become an avalanche producer if and when we receive another good snow load.
