Good morning, this is Ethan Greene with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.  Today is Monday, November 25, 2002, and it’s 7:30 am.


Current Conditions:

A cold front moved through yesterday afternoon bringing a few inches of snow to the mountains.  The snow came in “right-side-up” with about a half to an inch of snow with 8 – 12% water content accumulating by sunset.  An additional 5 to 7 inches of snow with 5 – 6% water fell overnight.  Storm totals are 6 to 7 inches in the upper portions of the Cottonwood Canyons and 3 to 4 inches in the Provo and Ogden Mountains and on the Park City Ridgeline.


This morning the skies are mostly clear with temperatures in the low teens at 8,000’ and near 10 degrees at 10,000’.  Overnight the winds were from the northwest in the 15 mph range, but early this morning they shifted to the northeast.


Avalanche Conditions:

During our latest dry spell the surface snow became loose and faceted.  Many of our observers noted that the weakest snow was on the snow surface or just under surface crusts.  This latest snow event did not add much of a load to the snowpack, but overnight there was enough wind to move it around and form new wind drifts.  Today these drifts could be quite sensitive so you should use caution when approaching them.  Overnight the wind shifted from the northwest to the northeast so look out for drifts forming in unusual places.


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

The avalanche danger today is MODERATE on wind loaded slopes about 35 degrees and steeper.   Otherwise the avalanche danger is generally LOW.


Mountain Weather:

The cold front that brought us a few inches of snow last night has moved off to the south.  Dryer air from the north will move into the Wasatch Range today bringing cooler temperatures, mostly clear skies, and gusty ridge-top winds.  Today high temperatures will be in the mid 20’s at 8,000’ and mid teens at 10,000’.  Winds will be from the northeast in the 15 to 25 mph range but along the ridgeline the gusts could be quite a bit stronger.  Tomorrow looks like more of the same with scattered clouds, northeast winds, and temperatures in the mid 20’s.
