Snowfall began in the mountains about , with probably a few inches of accumulation by now.† Winds are westerly 10 to 25 mph over the high ridges, with gusts to 35.† 8,000 foot temperatures are in the mid twenties.†
the past week there have been a surprising number of triggered avalanches in
the backcountry, several in the Wasatch and others in the Uintas.† Yesterday, I was caught and carried in a
loose snow sluff; a ride that was a little spookier than I enjoy.† Now northern
The weak layers are weakest and most widespread at mid and upper elevations on northerly facing slopes that donít get much sun.† Southerly facing slopes are crusted under the new snow and the crust will provide a good sliding surface.† East and west facing slopes are in between with a variety of crusts and weak layers.† Wind crusts, slabs and old bed surfaces also complicate the picture.† I think the recent warm temperatures have strengthened the lower elevation snowpack.† Slides in the new snow may step down into deeper layers, especially on northwest, north and east facing slopes.† As this storm develops today and Friday and over the weekend, be conservative and defensive in your backcountry travel.† Watch for collapsing and cracking in the new snow.† Keep to lower angle slopes.† With these types of weak layers slopes may be remotely triggered so watch the angle of slopes above and to your side.† Carry beacons and avalanche rescue gear and keep your party spread out.

The danger of human triggered avalanches is MODERATE this morning on mid and upper elevation wind drifted slopes, steeper than about 35 degrees.† Human triggered avalanches are possible.† The danger may rise to CONSIDERABLE as snowfall and wind continue today.† Shallow new snow avalanches may step down into deeper layers, creating more dangerous slides.†
(Provo Area Mountains and Western Uinta Mountains)
These areas have had a thin snowpack most of the winter, and the sugary weak snow is more common than in the Cottonwood Canyons.† The danger of human triggered avalanches is more widespread in the Provo and Western Uinta Mountains, especially where wind drifted.†
(Ogden Area Mountains)
Same as above.
Skies will be overcast today with snow, heavy at time this morning, becoming more showery during the afternoon.† Winds will be westerly 15 to 25 mph this morning, then shifting back to the south and southwest and increasing during the afternoon.† High temperatures will be near 30 degrees at 8,000 feet and in the twenties at 10,000.† At strong cold front will arrive about tonight, with strong winds, possibly some lightning and heavy snow.† Storm totals by sometime Friday could be about 10 to 18 inches.
The Wasatch Powderbird Guides will probably not be flying today, but if they do get out, will be in the Silver, Dayís, Cardiff, and Mineral Fork drainages of Big Cottonwood Canyon and in the Porter Fork and Alexander Basin drainages of Mill Creek.† For more information call 521-6040 ext. 5280.
