This year March is coming in like a polar bear!† Cold Canadian air has dropped the ridge top temperatures to below zero this morning.† 8,000 foot temperatures are around 5 degrees.† The Cottonwood Canyons received several inches of new snow yesterday afternoon and last night, with a trace to a couple of inches in other parts of the range but there was so much wind that amounts are hard to pin down.† Low level moisture and little storm energy produced more overnight snow at mid-elevations than what fell higher in the canyons.† Winds were strong for most of the night on the highest peaks and are now blowing 10 to 25 mph out of the north, with gusts to 30.
Snow surface conditions will be the few inches of new snow over a variety of sun and wind crusts and some settled powder.
There have been no avalanches reported from the backcountry since Monday but part of that dearth of activity may be due to lack of interest; there just donít seem to be many people in the backcountry this week. †Over the past 24 hours strong north and westerly winds and a little new snow will have developed shallow drifts that will be sensitive to the weight of a person today on steep slopes along upper elevation ridges and gullies.† The widespread underlying crusts will allow any triggered slides to move quickly and run far.†
the new snow and varied crusts are plenty of weak layers that complicate the
stability picture.† These deeper weak
layers may be triggered in isolated places and avalanches in the newer snow may
break down into deeper layers.† The

Many slopes have hard enough crusts under the new snow that it can be difficult to stop if you start sliding.
The danger of human triggered avalanches is MODERATE on slopes steeper than about 35 degrees with recent deposits of wind drifted snow.† Human triggered avalanches are possible.† There is also a possibility of triggering a deeper weak layer or that new snow avalanches may step down to these deeper layers, producing larger and more dangerous slides.† This is most likely in steep rocky chutes, slopes that have already avalanched earlier this season and in areas that have a thinner snowpack.†
areas have had a thin snowpack most of the winter, and the sugary weak snow is
more common than in the Cottonwood Canyons.†
