AVALANCHE ADVISORY

Tuesday, March 21, 20067:30 am
Good morning, this is Brett Kobernik with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Tuesday, March 21, 2006, and itís about 7:30 am.

 

Current Conditions:

Ridgetop temperatures neared freezing on Monday turning the snow damp on all aspects below about 10,000 feet.Ridgetop winds were from the southwest in the 10 to 15 mph range with a few higher gusts.This morning a period of snowfall laid down another layer of light density snow which produced about 6 to 10 inches of snow in most locations.Snow was still falling at the time of this publication but should taper off this morning.

Recent Avalanche Activity & Snowpack Discussion:

A few people still were able to find a few pockets that pulled out with slope cuts on Monday that produced some slab avalanches.These were all within the snow from the last storm and seem more prevalent around the Timpanogos terrain where a weakness formed early in the last storm.The largest was 18 inches deep and around 150 feet wide. (PHOTOS & INFO) The snow that fell this morning came in a very short period of time and I would expect to see evidence of natural loose snow avalanche activity once people get out this morning.The snow should already have stabilized somewhat to the point where natural activity is over.People out recreating will still be able to initiate activity mostly in the form of sluffing.Most of the instabilities from the last storm should have settled out but lingering pockets may be lurking in the steep upper elevation north facing terrain where you may find some slab avalanche activity.Another period of snow is expected this afternoon and if we see a period of high precipitation intensity the danger will rapidly rise.During these periods the snow can quickly become unstable and produce spontaneous natural avalanching.

Bottom Line:

The avalanche danger is MODERATE on slopes steeper then 35 degrees in areas that received the most snow and along the upper ridgelines where any wind drifting may have occurred.Watch for periods of rapid snowfall accumulation this afternoon and make sure you are traveling along ridges and out from under steep avalanche paths and gullies during these periods if they happen.The new snow will be sensitive to any warming so pay attention to temperatures today as well.

Mountain Weather:

Snowfall from this morning should taper off for a while before another wave of snow affects us this afternoon.4 to 6 inches more is expected with locally heavier amounts possible.Ridgetop temperatures will be in the upper teens to low 20s and ridgetop winds will be from the southwest in the 10 to 20 mph range decreasing as the day goes on.High pressure sets in for the next few days bringing warmer temperatures.
