a dull, spring-like two weeks, we finally are back in snowy times. Alta reports 8 inches of fairly light 10%
snow with a couple more inches expected this morning. They report 0.7 inches of water weight. With
the west to northwest flow, Big Cottonwood has around 6-8 inches at higher
elevations at mid canyon but only 5 inches at Brighton and there’s 2-4 inches
Today I’m thinking that the main problems will be fresh wind drifts along the ridges and other wind exposed slopes above tree line. As always, you should avoid any steep slope with recent wind deposits. Also, there will be a slight density inversion within the new snow, so you may find some soft, shallow slabs even in non-wind drifted areas. Finally, the past two weeks of clear weather created thick layers of weak, faceted snow and surface hoar on the old snow surface, mostly on wind and sun sheltered slopes above 9,000’. I’m thinking that this new snow probably doesn’t weigh enough to create widespread avalanche problems on the old, faceted snow, but Saturday’s storm will probably be enough weight to create more widespread problems and people will start triggering avalanches down lower on the slope than they expect. The avalanches conditions will be quite variable today and through the weekend, so be sure to be diligent about safe travel ritual. Cross avalanche terrain one at a time, avoid fresh wind drifts and put good slope cuts on every steep slope, even down out of the wind.
There is a CONSIDERABLE danger on any steep slope with recent wind drifts. This means human triggered avalanches are likely. There is a MODERATE danger on slopes steeper than about 35 without wind drifting.
a couple more inches of snow this morning in Little Cottonwood and another inch
or two in Big Cottonwood, but otherwise, most of the snow is mostly over. We should see clearing skies by afternoon. Ridge top winds should diminish through the
day and continue from the west to northwest.
Ridge top temperatures will be near 20 degrees today with 8,000’ temperatures
in the mid to upper 20’s. Saturday
