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

 

Current Conditions:

Today would be yet another great day to escape from the frosty, carbon monoxide smog and shopping sprees in the valley and get up into the warm, sunny mountains.With a very strong temperature inversion, overnight lows this morning are an amazing 38 degrees at 10,000í and 33 degrees at 11,000í.And today will be the last, nice, sunny day for a few days, so enjoy these summer-like conditions while you can.Yes, you have to get above 9,500 feet on northerly facing slopes to find decent snow, but amazingly enough Iíve still been finding quite delightful 4-8 inches of soft, recrystalized snow between 9,000 and 10,000 feet in wind and sun sheltered slopes that are not too steep. The total snow depth is only about two feet deep at the most, so continue to use old equipment you donít mind scratching up too much. Any slope exposed to the sun or the wind, however, is crusted and rocky.

 

Avalanche Conditions:

Thereís not much happening in the avalanche world these days with continued low danger on all slopes. The surface of the snow on wind and sun sheltered slopes continues to rot away and it has become extremely weak, sugary, faceted snow that runs thorough your fingers like salt crystals.On very steep slopes it sometimes runs down the slope in loose, sluffs, which could take you over a cliff or into a tree if youíre not careful.If nothing else, itís a good education to get out and see this extremely weak snow so that youíll know--beyond any shadow of a doubt--why you wonít want to be anywhere near them after they get a load of new or wind-blown snow.Also, today you may see some very localized wet sluffs on steep sun exposed slopes.Otherwise, everything is staying in place quite well.

 

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

The avalanche danger is generally LOW today, with very isolated loose sluffs of dry faceted on very steep shady and very isolated wet sluffs on steep sunny slopes.

 

Mountain Weather:

It will be yet another delightful summer-like day in the mountains, with warm temperatures and sunny skies.But get out early because we have some high clouds approaching from the south for this afternoon and evening.Highs at 8,000 feet will be in the mid 40ís with overnight lows in the mid 20ís.On the ridge tops, highs today will be in the mid to upper 30ís with 10-15 mph winds from the southeast. A closed low in California will drift across southern Utah over the next couple days and that will bring some clouds up from the south and cool down our temperatures a little.We may even see a few snowflakes in the mountains on Sunday and Monday but they probably wonít add up to more than a couple inches.†† The long range forecast calls for a brush-by to the north of us on Wednesday, which could bring some clouds and wind.Some of the long range computer models think we could get a larger storm in about mid December, but otherwise, it looks like continued dry weather.

 

General Information:

A great Christmas present for someone you love is an avalanche beacon.To help you decide which one to buy, we have 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.
