Avalanche advisory

Thursday, April 08, 2004,   7:30 am

 

Good morning, this is Andrew McLean with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Thursday, April 08, 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:

Tornadoes were about the only thing missing in yesterday’s weather, as we experienced thunder, lightning, hail, rain, flash floods, storm clouds and even a trace of snow.  The sponge is far from wrung out and will continue to deliver more moisture today, with the bulk of it digging in a bit to the east of us.  At least it won’t be windy, and if you can overlook the weather, the backcountry has some silky smooth fields of corn in the upper elevation shady aspects.

 

Avalanche Conditions:

With these sudden bursts of intense rain interspersed with direct hits of occassional sun, the snowpack is experiencing its own version of flash flooding.  Over the last four weeks it has developed a drainage system worthy of Los Angeles, but even that can get over run occasionally.  When this happens, small but very fast moving and dense avalanches spring from the slopes, as was witnessed in the Ogden area yesterday.  If you’re out touring in the rain, be alert for any rapid increases in intensity or a sudden warming up if the sun pokes through the clouds.  As a saving grace, today’s slightly cooler temperatures should help glue all of this in place.

 

Bottom Line for the Salt Lake, Park CITY, OGDEN AND Provo AREA MOUNTAINS:

There is a LOW danger of human triggered or natural avalanches this morning, which could rise to MODERATE by this afternoon, especially during periods of intense rain or direct sunlight.

Mountain Weather:

Thunder and lightning and hail – oh my!  Above 9,000’ it may turn to snow, with a trace to 1” expected throughout the day.  Temperatures will range from highs in the mid 40’s to overnight lows just below freezing at 8,000’.  Skies will remain mostly cloudy today through Friday, when they will finally start to clear up ahead of a drying northerly cold front.  This system will give the snowpack a stay of execution over the weekend, with temperatures cooling off by 10 degrees and a slight chance of snow showers.

General Information:

We will continue to issue morning forecasts through Sunday morning, and then we’ll go to intermittent afternoon updates.

 

The Wasatch Powderbird Guides did not fly yesterday, and if they do today, they will be in American Fork, White Pine, Mineral, Cardiff, Days and Silver Fork, with a return flight in Grizzly Gulch.

 

If you are getting into the backcountry, please give us a call and let us know what you’re seeing, especially if you trigger an avalanche.  You can leave a message at 524-5304 or 1-800-662-4140.  Or you can e-mail an observation to uac@avalanche .org, or you can fax an observation to 801-524-6301.

 

The information in this advisory is from the U.S. Forest Service, which is solely responsible for its content.  This advisory describes general avalanche conditions and local variations always occur.

 

I will be updating this advisory Friday morning.

 

Thanks for calling.
