SUMMARY >>> Danger by
ASPECT & ELEVATION
BOTTOM LINE
on slopes over 35 degrees
The danger for the Salt Lake, Park City, Provo, and Ogden area mountains is HIGH. Natural and human triggered avalanches are likely. Those without good route finding or avalanche skills should avoid the backcountry.

Heavy snowfall coming in on a west to southwest flow favoring the Provo, Ogden, and Park City produced 6-12” in the last 12 hours with water numbers in the .7”-1.4” range. Temperatures remained warm in the upper twenties to low thirties with an average rain/snow line at 7500’. The winds averaged 20-30mph along the higher ridgelines most of the night, but have since calmed to less than 20mph.

Danger over the next 24 hrs The sheer amount of water weight in the last 12 hours, the at-times snowfall rates of 2-3” of snow/hour and the expectation of another half inch to inch of water weight will easily snap the rubberband of our hapless snowpack. The new snow is falling on a variety of old snow surfaces, but will be enough to step down into some of the weakest sugary faceted snow we’ve seen in years. The higher snow and water numbers impacted the areas with a weaker snowpack, consequently, the danger may be even more pronounced outside the periphery of the Cottonwood Canyons.

Danger over the next 24 hrs The high rain/snow line will produce wet avalanching and be more pronounced on the shady mid and low elevation slopes. They'll have the potential to gouge to the ground and pile up sizeable debris piles. Ice climbing should be avoided and even snowshoers should avoid walking in terrain adjacent to steeper slopes.

SEASONAL Wx CHARTS We’ll see a bit of a break in the action this morning, but the next wave of moisture should bring an additional 4-8” mid-morning through late tonight. Temperatures will be in the low to mid-twenties at 10,000’ and mid-thirties at 8000’. The west to southwest winds will blow 20-25mph along the higher ridges. A cold front will impact the area late this afternoon with veering winds and dropping temperatures.
