Good morning, this is Ethan Greene with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Sunday, November 24, 2002, and itís 7:30 am.

 

Current Conditions:

The clouds began to roll in yesterday afternoon and it almost felt like winter in the mountains.We picked up about a half inch of wet snow above about 9,000í, but thatís barely enough to cover all the rocks.This morning the skies are mostly cloudy and temperatures are in the low to mid 20ís at 8,000í and upper teens at 10,000í.The winds are blowing in the 30 mph range from the west with some gusts over 50 along the highest ridgelines.

 

A few patches of recrystalized powder still exist on slopes sheltered from both the wind and sun.Elsewhere, there is a nice variety of wind and sun crusts creating interesting to frustrating conditions.On sunny aspects the snow is generally supportable above 9,000í.

 

Avalanche Conditions:

Cooler temperatures and some cloud cover will reduce the avalanche potential today.With very little new snow in the last week there are few new avalanche problems.The greatest danger in the backcountry may be crashing into a hidden rock or log.

 

Time and mild temperature have greatly reduced the change of triggering a deeper hard slab avalanche.But if youíre headed into steep terrain in mid and upper elevations areas they may be isolated weak areas where you could trigger a hard slab.

 

Bottom Line (SLC and Provo Area Mountains):

The avalanche danger is generally LOW.

 

Ogden Area Mountains:

The avalanche danger is generally LOW.

 

Mountain Weather:

An upper level front will move through northern Utah today bringing increased cloud cover and cooler temperatures.Expect ridge-top winds to be from the west and shifting to the northwest during the day.Wind speeds are fairly strong this morning but should drop into the 15 to 20 mph range by mid day.High temperatures will be near 30 degrees at 8,000í and in the low to mid 20ís at 10,000í.Our best chance for precipitation is tonight.Cross your fingers because we expect to see only an inch or two of new snow by Monday morning.Ridge-top winds are expected to be in the moderate to strong category from the east on Monday.
