Forecaster: Dave Medara

BOTTOM LINE

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

Danger Rose Tutorial

Watch new snow accumulations, they may change the avalanche conditions from our current danger rating very quickly. Variable conditions are being reported in SE Utah. There is some good powder skiing on sheltered East and North facing slopes. There is also some wind damage being reported out there. Be careful in wind affected areas as there are some weak layers in the upper pack. MODERATE avalanche danger on mid and upper elevation shady side slopes. Any significant new snow totals from this storm cycle we are entering will cause a significant spike in the avalanche danger.


CURRENT CONDITIONS

Our snowpack totals have slipped to below 100% of normal in the La Sals (108%in the Abajos) and driving up from the south you can really appreciate that fact. The La Sals look really barren. With the bulk of our SE Utah snowpack having fallen in December, the wind and sun have had a lot of time to work on the sunny slopes we see from the highway and from Moab. What is surprising is the great quality snow we found on the North Face of Abajo Peak on Thursday. On a short tour up North Canyon in the Blue Mountains out of Monticello, we found good creamy powder skiing in nicely spaced trees on a steep NW facing slope. What we found was better than expected and more of this type of skiing can be found if you head out to the right locations which are, as usual, mid elevation E-NE-NW facing slopes. If you're looking for something different, check your map out and go check out the Abajos. There is easy access, some really good terrain and new snow (hopefully) on the way. The old Blue Mountain ski resort is a great tour and that's just the start. San Juan County is quick to plow access along the Blue Mountain loop road as well. As of this afternoon, we'd only had a trace of new snow and our Gold Basin study plot stands at 38 inches.

The roads to the Geyser Pass Trailhead and the Dark Canyon Trailhead are plowed and in great shape providing access for 2wd vehicles. If we get any of the forecast snow tonight, access will no doubt be tougher.

LUNA volunteers groomed the the Geyser Pass Road today and the Upper Nordic Loop on the East side of the pass. Good job Michael and Tony.


RECENT ACTIVITY

We'll be watching closely as the snow piles up into next week. I expect some action depending on our snow/wind totals.

Right now, there is not a lot going on in the avalanche realm. We're almost two weeks out from the last storm. and there is not a lot of slab tension being found as people get farther into the mountains. What is being consistently found are some very weak layers above and below a rime crust that formed at the start of our last storm. With winds this past week I am hesitant to lower the Avalanche Danger below MODERATE on mid and upper elevation E-NE-NW facing slopes above treeline, but I think we are on the lower end of that. RIGHTNOW.

So far we've picked only a skiff of new snow but expect the avalanche danger to rise in relation to the wind and snow we receive from this next series of storms. We've got an old snowpack with several weak layers in the upper foot or so and it is not going to take much snow to push us into an avalanche cycle.
