Happy Thanksgiving! This is Evelyn Lees with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Thursday, November 28, 2002, and itís 7:30 am. We wish you a wonderful day with family and friends.


Current Conditions:

Up out of the valley inversion, skies are clear in the mountains this morning.Temperatures are warming, and are currently in the mid 20ís to low 30ís.Winds are light, generally less than 10 mph, and variable in direction.


Areas of soft, recrystalized snow exist on mid and upper elevation shady, northerly facing slopes. Elsewhere, there are widespread areas of supportable and breakable sun and wind crusts.The meager snowpack is limited to the mid and upper elevations, and even there, total snow depths are only 12 to 30Ē.So if youíre getting out for the first time this holiday weekend, choose a high elevation trail head, take your rock boards and be alert for hidden obstacles.Snowshoeing would be an excellent way to travel in the mountains today.


Avalanche Conditions:

Loose snow sluffs will be the principal avalanche concern today.On very steep, shady slopes the snow surface is weakening, and dry loose sluffs can be triggered by a person. Some of these are large enough to knock you off your feet or take you for a ride.In addition, a few cracky winds slabs may still be sensitive to the weight of a person along the higher ridges.With such a shallow snow pack, even a short ride could be dangerous with a multitude of rocks to hit.


The snow on the sunny slopes will warm up today, and may produce a few wet sluffs on steep slopes, especially near rock bands that heat up under the sun.So if the snow gets wet and sloppy, stay off and out from under steep sunny slopes.


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

The avalanche danger is generally LOW today, isolated to loose sluffs on very steep shady and sunny slopes and a few old wind slabs. Due to low snow conditions, the consequences of going for a ride could be serious.


Mountain Weather:

It will be a delightful day in the mountains, with mild temperatures and light winds.8,000í highs will be in the mid to upper 40ís, and ridge top winds will remain light and variable.Skies will be clear tonight, with light southwesterly winds and lows in the mid 20ís.The ridge of high pressure will continue over the area through Saturday morning, followed by a weak storm on Sunday which will bring cooler temperatures and a chance of snow showers.


General Information:

A great Christmas present this year for someone you love would be an avalanche beacon.If you want to know which one to buy, Iíve posted a couple recent tests of various brands of avalanche beacons on the web.Point your browser to www.avalanche.org and click on Salt Lake, then on Education.At the same location, you can find a complete list of avalanche talks and multi-day classes.
