Ogden Avalanche Advisory

Forecaster: Evelyn Lees


Our partners, the Friends of the Utah Avalanche Center, with the Snowbird Renaissance Center, are hosting the annual Utah Backcountry Awareness Benefit Dinner and Silent Auction Friday, February 13th, from 5:30-9:00 pm, at Snowbird. It’s a bit of a splurge, but it’s always a very enjoyable evening. Included is dinner, a silent auction, inspirational speaker Chris Waddell chronicling how he overcame a life-changing college skiing accident to become the most decorated male skier in Paralympic history, plus live entertainment by “Stormy Mountain Boys”. For details and tickets, go to the Snowbird Renaissance Center's web site.

Danger Rose Tutorial

The avalanche danger is MODERATE on mid and upper elevation slopes steeper than about 35 degrees, facing northwest through east. MODERATE means human triggered slides are possible. If the winds increase where you are today, fresh drifts of windblown snow will rapidly build, and as always, should be avoided on steep slopes.


Yesterday’s quiet little storm spread snow evenly across the northern mountains from Ogden to the Cottonwoods, with most areas receiving 8 to 11” above about 8,000’. Densities averaged 6-7%. The Provo area mountains pulled ahead on the southerly flow, picking up just over a foot, with 1.3 inches of water, at 7,500’, and I would suspect even more at the higher elevations. This morning, skies are partly cloudy in the Ogden area mountains, temperatures are in the low twenties, and the southeasterly winds are surprisingly light. Even the exposed stations are averaging only 10 mph, and gusts are less than 20. The new snow isn’t quite enough to fill in all the old tracks, but you’ll feel them less on the shady slopes with underlying soft snow and on lower angle slopes.


Yesterday, in the Ogden area mountains, sluffs, super-soft slabs and wind drifts were easily triggered within the new snow on steep slopes, most sensitive and longest running on slopes facing northwest through east. Size wise, most of these slides were harmless, but some were big enough to catch and carry an unaware person. The snow was the most cracky and sensitive in terrain affected by the few hours of stronger, gusty winds or during the time of heaviest snowfall yesterday morning.


      Over the next 24 hours.

Once again, I expect it will be easy to trigger sluffs and very soft slabs in the new snow today, especially on the shady mid and upper elevation slopes. Here the new snow landed on weaker sugary facets and surface hoar. These are more persistent weak layers, and remain sensitive. Due to the shallow depth of the potential slides, careful slope cuts and cornice kicking will be effective today. But consider the terrain you’re in – continuously steep terrain or a potential ride into trees, a gully or off a cliff may make a slope cut too dangerous an endeavor.

With warm temperatures, damp sluffs will be possible on steep, lower elevation slopes, including northerly facing ones.


      Over the next 24 hours.

The current wind speeds are so slow; it’s hard to believe they’ll remain like that all day. So if the southerly winds increase where you are today, they will rapidly whip up some deeper sensitive wind drifts along the ridgelines, loading the same northerly facing slopes with the weaker underlying snow.


Another band of moisture is struggling north this morning, and may not quite reach the Ogden area mountains. If it does, it will generate mostly cloudy skies and light snow showers. A trace to 2 inches of snow is possible today and again tonight. The southerly winds may increase into the 10 to 20 mph range, with gusts to 25. Temperatures will be in the low 30s at 8,000’ and the low 20s at 10,000’. Mostly cloudy skies with occasional snow showers will continue through Monday, with a better chance for significant snow Monday night as a cold front moves through.


Wasatch Powderbird Guides did not fly on Friday and most likely won’t fly today due to weather. Operations planning page is here.

Beacon training parks are up and running! There is one at Snowbasin, one on the Park City side at the top of Canyon’s gondola, one in Little Cottonwood near the Snowbird parking structure on the bypass road, and in Big Cottonwood a training park is at the west end of Solitude's lower parking lot.
