Good Morning.This is Tom Kimbrough with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Friday, November 29, 2002, and itís 7:30 am.


Current Conditions:

As the valley smog thickens there is all the more reason to get up into the mountains where the weather is delightful, even if the snow cover leaves a lot to be desired.Skies are clear in the mountains this morning, with overnight lows in the upper twenties and low thirties.Winds are light and variable.


There are patches of soft, recrystalized snow on mid and upper elevation northerly facing slopes.Elsewhere, there are widespread sun and wind crusts.The meager snowpack is limited to the mid and upper elevations with snow depths of about zip to a couple of feet.Snowmobiling is limited to mid and upper elevation roads and trails.Snowshoes are a good choice for the current conditions.


Avalanche Conditions:

Loose sluffs of the surface snow on shady slopes is the main avalanche consideration at this time. On shady, northerly facing places, the snow surface has become loose and sugary and will move easily with a person on slopes approaching about 40 degrees steepness.Some of these sluffs could be large enough to knock you off your feet and take you downhill.In addition, there are a few shallow wind drifts along the higher ridges that could crack under the weight of a person.If a sluff or a shallow drift does catch you, the ride would be like a trip down a big cheese grater considering all the rocks and obstacles that you could be dragged over.


Although there isnít much snow left on southerly facing slopes there is a possibility of a few wet snow sluffs off upper elevation rock bands that heat up under the sun.


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

The avalanche danger is generally LOW today, isolated to a few loose sluffs on very steep shady and sunny slopes and some old wind slabs.


Mountain Weather:

It will be another delightful day in the mountains, with warm temperatures and light winds.Highs at 8,000 feet will be in the mid to upper 40ís and near 40 at 10,000.Expect increasing clouds tonight with light southerly winds as a weak storm approaches for the weekend.Saturday will be mostly cloudy and cooler and light snow is possible on Sunday.Accumulations on Sunday are likely to be only a few inches at best and, unfortunately, high pressure will return next week.
