AVALANCHE ADVISORY

Tuesday, January 17, 2006  7:30am
Good morning, this is Brett Kobernik with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Tuesday, January 17, 2006, and it’s about 7:30 am.

 

Drew will be teaching a Basic Avalanche Awareness class at Black Diamond Tuesday night at 7pm.  For more information, call BD at 278-0233.

Current Conditions:
”Epic”, “sensational”, and “the best day of the season” were phrases used to describe conditions in the backcountry yesterday.  The light density new snow with mostly stable conditions certainly gave backcountry travelers a pleasurable day.  Current ridgetop temperatures remain cold and are in the low to mid teens at most locations.  Winds on Monday were generally light but did pick up just slightly overnight with ridgetop speeds in the 15 to 20 mph range from the northwest with sustained speeds at the highest elevations in the 40 mph range over the last 6 hours.

Avalanche Conditions:
The mountains of northern Utah are enjoying a period with a very stable basal snowpack.  With no persistent weak layers, the main concern with each new storm remains in the upper portion of the snowpack.

With a few reports of drifting snow from yesterday and slightly higher wind speeds overnight, today fresh wind drifted snow will be the main concern.  The very light density snow that fell over the weekend is prone to transport and can easily form sensitive drifts on lees slopes.  With lower elevation wind speeds not doing much, I’d expect to see these drifts mainly at the higher elevations on northeast through southeast facing slopes.  These drifts may not prove to be very sensitive however; any fresh wind drifts are suspect until proven otherwise.  While traveling today, stomp on drifts in safe areas along ridges to check for cracking.  Also, use slope cuts before just diving into steeper slopes.

Bottom Line:

For today the avalanche danger is generally LOW.  You will find areas along the upper elevation ridges where the danger of triggering a fresh wind drift is MODERATE.  You will find these drifts mainly on northeast through southeast facing slopes steeper then 35 degrees.

 

Mountain Weather:

For today we’ll see mostly cloudy skies with ridgetop temperatures getting up into the low 20s with ridgetop wind speeds in the 15 mph range.  Tonight through Thursday night will bring another storm which could produce 1 to 2 inches of water translating into a couple feet of snow.
