Avalanche advisory

Tuesday, January 13, 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 Tuesday, January 13, and itís 7:30 a.m.

Current Conditions:

After a calm, clear night, it looks like today will be a repeat of yesterday, complete with the smog and cooler temperatures in the valleys.If you need some inversion therapy, the mountains will be clear and sunny, with temperatures in the low 40ís during the day and a light breeze out of the northwest. The 8,000í overnight lows were down to the mid 20ís with a light SW breeze.Turning and riding conditions currently range from dwindling pockets of tired powder to an early harvest of corn snow on the sunny exposures.


Avalanche Conditions:

During this current spate of warm weather, wet avalanches are the main concern.These can take the form of point releases on steep, sun exposed slopes, or glide avalanches in areas with smooth underlying rocks or grassy slopes.The point releases are most likely to occur just below rock outcropping on steep, sunny slopes, especially at lower elevations.They are often preceded by pinwheels or roller balls and are most active during the warmest part of the day.


With glide avalanches, itís much harder to predict exactly when they will occur.These tend to be thicker slabs of deep, homogenous snow that fail to their full depth and produce large debris piles. If you are in an area where large horizontal cracks are developing in the snowpack, give the run-out zones a wide berth and avoid areas with known smooth underlying ground features.


During this period of warm weather, the basic rules of springtime mountain travel will apply, including getting earlier starts, staying out of terrain traps and keeping an eye and ear out for grumbling snow coming down from above.


Bottom Line for the Wasatch Range, including the Salt Lake, Park City, PROVO, and Ogden MOUNTAINS:

The danger is low today and human triggered avalanches will be unlikely. ††During the heat of the day, the danger of wet slides will increase to moderate as the snowpack warms up.


Uinta Mountains:For Uinta specific information, click on Western Uintas on the advisory page or phone 1-800-648-7433.


Mountain Weather:

High pressure continues to be the main event for today and clear, sunny weather will persist. At 8,000í, temperatures will be in the low 40ís during the day then drop down into the low 20ís at night with light winds out of the NW.This pattern is expected to continue through Wednesday, with Thursday night possibly providing a break in the high pressure holding pattern, with a slight chance of snow, or at least some partly cloudy weather.
