Avalanche advisory

Friday, February 13, 2004,†† 7:30 am


Good morning, this is Bruce Tremper with the Forest Service Utah Avalanche Center with your backcountry avalanche and mountain weather advisory.Today is Friday, February 13, 2004, and itís 7:30 a.m.


Current Conditions:

My face is sore this morning from getting blasted by below zero temperatures and winds along the ridge tops for the past couple days. But this morning, the ridge top temperatures have thankfully warmed 20 degrees from yesterday morning and they have rehabilitated themselves to a balmy 15-20 degrees and winds are relatively light. Although the winds have scoured the higher wind-exposed peaks, the cold temperatures have preserved the great powder at mid and lower elevations.Thereís a bit of a pesky sun crust on the steeper south facing slopes.


Avalanche Conditions:

The only avalanche activity yesterday was sluffing of the light, dry powder on steep slopes. Some of these sluffs were large enough to bury a person or take them over a cliff, so be sure to practice all your sluff management techniques like moving across the fall line or letting the sluffs run out ahead of you. Although we continue to experience widespread collapsing of the snow at lower elevations and in thin snowpack areas, we just havenít had any weight added to these buried weak layers for a week or so, and they donít seem inclined to avalanche. More importantly, today, as temperatures warm dramatically at upper elevations and the inversions mix out at lower elevations, some of our dry, cold powder on the surface could quickly turn damp or wet and you may see some sluffing of wet snow especially on steep sun exposed slopes and on steep lower elevation slopes. For instance, three days ago when it was warmer, one woman was caught in one of these wet sluffs on a southeast facing slope in Butler Fork and taken for a short ride.


Bottom Line for the Wasatch Range, including the Salt Lake, Park City, provo and OGden AREA MOUNTAINS:

The avalanche danger will be generally low today with localized areas of moderate danger of loose, dry sluffs on steep slopes and damp to wet, loose sluffs on steep sun exposed slopes and lower elevation slopes when the cold, dry snow gets wet for the first time.

Mountain Weather:

Today should be clear and sunny with dramatically warmer temperatures.On the ridge tops, the temperatures should climb up to the upper 20ís later in the day. Ridge top winds will remain light from the northeast, switching to northwest later in the day. Down at 8,000í the day time highs should climb into the mid to upper 30ís.On Saturday, we will have increasing clouds with a weak system bringing light snow for Saturday night and cooling ridge top temperatures down again to the mid teens. The extended forecast calls for cloudy and light snow again on Sunday, then a stronger system for Tuesday night to about Thursday.
