AVALANCHE ADVISORY

Saturday, February 25, 2006  7:30am
Good morning, this is Evelyn Lees with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Saturday, February 25, 2006, and it’s about 7:30 am.

 

There are several free automated avalanche beacon practice areas open, including one at Canyons, one on the by-pass road near Snowbird and one in the northwest corner of the lower lot at Solitude.  They are really easy to use, and well worth stopping for a quick practice session.

 

Current Conditions:

There is a strong feeling of spring in the air, with the sun high in the sky and warm daytime temperatures.  This morning, skies are clear, and mountain temperatures have cooled into the teens to low 20’s.  Winds are light, less than 15 mph at all stations.  If you tiptoe around old tracks, sun and wind damage, there is still fine dry powder to be found on the very shady, wind sheltered slopes.  The sunny slopes have a wide variety of supportable and breakable crusts, which soften with daytime heating.  A small arsenal of skin wax, sun screen, and other spring time accoutrements will help your day go more smoothly.

 

Avalanche Conditions:

A few small sluffs and one explosive triggered wind slab in a ski area (10” deep by 80’ wide, east facing, 10,200’) are the sum total of avalanches reported yesterday.  Also, sometime during the past 2 days, a natural cornice fall in Mineral Fork triggered a long running slab/sluff that went full distance and filled the creek bottom 8 feet deep. 

 

Today, there are still a few places where a person could trigger an old wind slabs on a steep slope.  Though small, they could easily knock you off balance, and if you’re in steep terrain, send you for a ride or off a cliff.  Dry sluffs can also be triggered on steep shady slopes.

 

On the steep, sunny slopes, it will be possible to trigger loose, wet sluffs as the day heats up and the snow gets damp and sloppy.  Again, the type of terrain you’re in matters – don’t get caught above cliffs or on very steep slopes where even a small sluff can send you for a ride. Avoid terrain traps such as gullies where even those undersized sluffs can pile up deeply.  In addition to the sunny slopes, the snow on mid and lower elevation shady slopes will also get damp today. With several days of heating, cornices are becoming sensitive and there is a greater chance for glide avalanches to release. 

 

Bottom Line:

Today, the avalanche danger is mostly LOW.  There are pockets of MODERATE danger on slopes steeper than 35 degrees where it may still be possible to trigger an old drift of wind blown snow.  The avalanche danger will also increase to MODERATE on and below steep, sunny slopes with day time heating, where wet, loose sluffs will be possible.

 

Mountain Weather:

High pressure will strengthen across the region today and tomorrow, bringing warm temperatures and mostly sunny skies.  Highs today will be near 40 at 8,000’ and in the mid 20’s at 10,000’.  Winds will shift to the southwest and remain light, less than 15 mph.  Sunday will be warm and breezy.  The Tuesday night storm is looking a bit weaker on the latest model runs, but should still provide a small shot of snow, and will be followed by another storm late in the week.
