Avalanche advisory

Sunday, December 19, 2004

 

Good Morning.This is Brett Kobernik with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Sunday, December 19, 2004, and itís 7:30 in the morning.

 

Free Beacon Rescue Training Centers are now open at Snowbird and the Canyons.For more information go to wasatchbackcountryrescue.org.

 

Current Conditions:

Above the valley fog skies are clear this morning with temperatures in the mid 20ís at 10,000í.WNW winds are in the 15 mph range along the ridge tops.There is a thick supportable crust on southerly facing slopes with good corn conditions being reported.You will find dense settled powder on mid elevation northerly aspects.There is an annoying crust on all aspects below around 8000í that makes the approaches and exits quite tricky.

 

Avalanche Conditions:

Yesterday was another quiet day with no new avalanche activity reported.The slab continues to gain strength as well as the buried weak layer from November.Although the snow pack is gaining strength, I am still steering clear of steep slopes that have no sign of recent avalanche activity.Given that the size of an avalanche could still be large right now itís best to give the snowpack some more time to heal.This slab has taken on hard slab characteristics in that it may let more then one or two people cross it before it fractures.Continue safe route finding techniques.Only expose one person at a time to avalanche slopes and clear the runout zones at the bottom.

Bottom Line (SLC, Park City, Ogden and Provo Area Mountains):

The avalanche danger remains MODERATE on slopes steeper than about 35 degrees, facing northwest thorough easterly aspects. This danger is most pronounced outside of the Tri Canyon areas as well as in steep, shallow, rocky areas.The danger is more localized in the Tri canyon area.

Mountain Weather:

Today 10,000í temperatures will be in the low 30ís with winds from the west at around 15 mph picking up a bit this afternoon.8000í temps will climb into the low 40ís.A weak disturbance will move through the area on Monday with little chance of precipitation.On Tuesday a very cold air mass with stronger north winds will move in.This system has a slightly better chance for snow but storm totals donít look to promising right now.
