Danger Rose Tutorial

Tuesday, December 8:

There is a MODERATE danger on steep drifted slopes in the backcountry. You could trigger shallow soft slab avalanches on exposed upper elevation slopes steeper than about 35 degrees with freshly wind-deposited snow...


8000' Snotel sites report 3 or 4 inches of new snow from overnight. Hitting rocks or other shallowly buried obstacles probably still presents the largest safety concern in most areas.

Riders still pretty much have to stay on snow covered upper elevation roadways. Remember to slow down and watch out for pedestrians, especially in congested areas like Tony Grove.


Despite of a couple inches of new snow, easterly winds have been whipping it up and we noticed a couple small triggered soft slabs on very steep slopes south of Tony Grove Lake. One snowboarder told of being caught and carried for a short distance.

(go to our current conditions page, Here; for more details.)


      Over the next 24 hours.

Easterly winds over the weekend and northwesterly this morning may have built some small fresh wind slabs with the light density new snow. These slabs in many cases have formed right on top of weak faceted snow or feathery surface hoar, and you might trigger soft slabs around a foot deep on steep upper elevation slopes. I'd be especially cautious on exposed slopes and around terrain features where cross-loading has drifted-in significant light fresh snow.


It'll be very cold again today in the mountains with cloudy skies and light density snow, perhaps a another 4 inches today.....Expect moderately strong northwest winds to keep wind chills quite low and intensify drifting. As the flow shifts and remains out of the north-northwest, expect the coldest weather yet of the season in the next couple days with a chance for more periods of light snowfall...

Looks like we'll have to be satisfied with this nickle and dime action as large accumulations continue to impact most other areas in the state....


We will be issuing intermittent avalanche advisories as conditions warrant. I'll begin to issue regular advisories later in December and when the winter season really gets rolling....
