Ogden Avalanche Advisory

Forecaster: Drew Hardesty


Whole Foods Market in Cottonwood Heights is helping to raise funds for avalanche education. The store, at 6930 S. Highland Drive, will donate 5 percent of its net sales on Jan. 13 to the Utah Avalanche Center. We will present a 50-minute “Know Before You Go” safety presentation there at 7 p.m.

Bruce Tremper will be giving a Science of Avalanches talk at the SLC REI on Tuesday night. Go to our home page calendar for more details on this and other upcoming events.

Danger Rose Tutorial

Most of the backcountry continues to have a LOW danger. Pockets of MODERATE (Level 2) danger exists for minor super soft wind slab development along the high lee ridgelines. In the wind affected areas (high northeast to southeast facing slopes), I expect the shallow slabs to be very sensitive and it’s possible that they may be triggered at a distance. Any moving snow is likely to run fast and far, gathering plenty of the low density snow on the way to the runout.


Snow totals look to be in the 1-3” category with the upper Cottonwoods squeezing the most water out of stone. Or rather, snow out of water. It’s pure smoke. Less than 3%. It looks like we’re about done, though we can expect off and on flurries throughout the day. Temperatures plummeted to the single digits and the winds, thankfully, are light except along the highest peaks and ridgelines, where they’re just starting to blow 20-30 gusting to 40. Riding conditions remain excellent in the untracked wind and sun sheltered terrain.

Mark your calendars. We’ll be referring to this now buried weakness as the January 8th surface hoar layer. Clear skies, cold nights, high humidity, light wind…that lucky combination of meteorological phenomena that over the past week recrystallized the snow on the surface and grew the sheets of surface hoar above. Unfortunately, it wasn’t systematically destroyed prior to this new snowfall – so it’ll be well preserved until we see the next weather event of heavy snowfall and/or heavy wind loading.

Sluffing will be the primary concern on the steepest, highest, confined terrain.

One can also expect to see development of some shallow yet very sensitive super soft wind drifts along the highest lee northeast to southeast facing slopes. It may be possible to trigger these from a distance, though I don’t imagine that they’d pose too much trouble.


Occasional flurries and potential lake bands of snow are likely throughout the day. The northwest winds should become light by late morning and less than 15mph. Temps will remain in the icebox, dropping to near zero degrees Fahrenheit. We’ll get some clearing later Monday into Tuesday with perhaps the next storm on tap for Thursday night into Friday. The weather models backed off the strong series of storms for late week and weather forecast confidence is low toward the end of the 7 day period.


If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
