Danger Rose Tutorial

There is a LOW avalanche danger in the backcountry and avalanches are unlikely.  Watch out for hard and slippery snow conditions; avoid uncontrolled falls on steep slopes, especially above trees or exposed rock.


Thanks to the dense snow and the rain on the 12th and 13th and more recent cold nighttime temperatures, there’s still some decent snow coverage above around 8000’. What snow remains is quite solid, even icy, and you’ll likely find scratchy conditions again today, especially in the shade.  Bullet-proof snow conditions are not super common in Utah, and we need to understand the limitations of the equipment we normally use in the mountains.  Very hard snow conditions may call for you to reevaluate your planned route or at least throw the crampons and ice axe in the pack…. 


      Over the next 24 hours.

The remaining snow is now rock solid almost everywhere.  We'll need to monitor things when snow starts to fall again, as many avalanche starting zone are nicely filled-in and smoothed-out.  We'll have a nice bed surface in place and avalanche conditions may quickly develop.


The high pressure system will gradually move east of the region and a warm southerly flow will develop ahead of a couple split storm systems, which will affect the region during the long Thanksgiving Weekend.  With a southern California closed low passing well to the south, our best hope for a couple inches of snow comes Wednesday night as the northern branch of the low clips by to the north.  Another closed low will form and bring moisture well south of the region later in the weekend before another high pressure system takes up residence over the Great Basin bringing fair weather at least through the first part of next week.
