Avalanche Advisory
| Advisory: Salt Lake Area Mountains | Issued by Evelyn Lees for November 25, 2012 - 5:46am |
|---|
 
Above 9,500 ft.
8,000-9,500 ft.
Below 8,000 ft.

bottom line The snowpack is mostly stable, and the avalanche danger is Low today. Use normal caution and travel one at a time on steep slopes.

current conditions The strong valley inversions extend into the mountains, where temperatures in the canyon bottoms are in the 20’s this morning, the mid elevations are in the 30’s to low 40’s, and the highest peaks cool back down into the mid 20’s. Winds are from the southwest, and speeds increased just in bit in the past few hours – averages are 10-15 mph, with gusts to 25. Upper elevation travel remains reasonable on smooth, shady slopes with 2 to 3 feet of snow, but entrances and exits are the hard part, with mixes of rock, dirt and ice in places, and hitting a rock or stump remains a significant hazard. |

recent activity No new avalanche activity was reported from the backcountry or resorts yesterday. |

description
It has been almost 2 weeks since the last snow, and there is not much going on avalanche wise. Very steep, high elevation shady terrain has a slightly higher avalanche risk – of perhaps triggering an old wind drift or a small sluff that could knock you off your feet. Even with the warm temperatures, the snow is changing – on shady, mid and upper elevation slopes the snow surface is faceted and loose, and shallow areas are weakening from top to bottom. |
 |
weather Another weak, dry cold front will cross northern Utah this afternoon. This will bring nothing more than a few clouds, a wind shift to the northwest, and slightly cooling temperatures. Bands of mid to high level clouds will cross northern Utah today, with temperatures warming into the upper 30’s at 10,000’. The light winds will shift to the west, and then northwest by this evening. Averages will remain in the 5 to 15 mph range, with only the highest peaks occasionally gusting above 25 mph. Then it is back to warm, dry high pressure through the end of the month. |
