Avalanche advisory

Wednesday, March 31, 2004,   7:30 am

 

Good morning, this is Evelyn Lees with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Wednesday, March 31, 2004, and it’s 7:30 a.m.  This forecast is brought to you in partnership with the Friends of the Utah Avalanche Center, supported in part by the Uinta Brewing Company.

 

Current Conditions:

The warm, drought promoting, snow melting weather continues.  Overnight, under mostly clear skies, temperatures cooled only into the mid 30’s to low 40’s at the 9 to 11000’ elevations. The southwesterly winds have decreased, and are generally in the 5 to 15 mph range, with gusts to 30.  

 

The variable snow surface conditions include everything but large expanses of soft, dry powder.  The majority of slopes are sun or wind affected, with a combination of both breakable and supportable crusts.  The best chance of finding crusts that will soften but stay supportable may be on mid elevation slopes and on steeper south to southwest facing slopes. 

 

Avalanche Conditions:

There was one human triggered slide reported from the backcountry yesterday.  It was late in the day on the northwest face of Gobblers Knob, involved the new snow running on the old crust, and ran the full length of the slope.  I’m assuming it was a damp sluff, and when I get a few more details, I’ll post them on the avalanche list later this morning.  Today, increasing winds and clouds should help off set the warmer temperatures and keep a lid on natural wet activity.  But the snow will definitely get damp and soggy enough that loose, wet sluffs can be triggered by people on steep slopes, and these sluffs have the potential to be long running due to the slick, underlying crusts.  So as always, when the snow gets wet and sloppy, move to a different aspect and stay off of and out from under steep slopes.   Yesterday, none of the isolated old wind drifts seemed sensitive, but still approach steep slopes with rounded waves of wind blown snow with caution.

 

Bottom Line for the Salt Lake, Park CITY, Provo, and ogden AREA MOUNTAINS:

The avalanche danger is LOW this morning.  With daytime heating, the danger will rise to moderate on steep, sunny slopes and all steep low elevation slopes.

Mountain Weather:

A warm southerly flow will continue over northern Utah today and tonight, with a cold front expected to arrive around sunrise on Thursday.  It will be ridiculously hot again today, with highs near 60 at 8,000’ and near 45 at 10,000’.  The southerly winds will increase throughout the day, into the 25 to 35 mph range by afternoon.  Clouds will also increase, with a slight chance of afternoon thunder showers.  Cloudy, warm and windy tonight, with temperatures dropping into the low 30’s.   Thursday will return us to winter, with the models advertising 4 to 8” of snow, with locally heavier amounts.

I will update this advisory Thursday morning.

 

Thanks for calling.
