Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Mark Staples for Monday - December 11, 2017 - 6:54am
bottom line

The avalanche danger is LOW. Small slides are unlikely but could be triggered in isolated areas, mostly upper elevation northerly slopes and some east facing slopes that received wind drifted snow last Thursday.

special announcement

With no change in conditions expected or any storms on the horizon, we will be issuing intermittent advisories.

current conditions

Clear cold nights and warm sunny days. Temperatures in the mountains remain warmer than the valleys, especially through the night. Many moutain locations have morning temperatures in the upper 20's and low 30's F while many valley locations have tempeatures in the teens F.

View the latest observations here.

South aspects are forming an ice crust at the surface as they dampen and refreeze each day. Most other aspects have dry powder which seems even drier as it facets and looses cohesion. Many slopes were affected by N and NE winds but sheltered slopes still have good riding conditions. Coverage remains thin, but the snowpack remains mostly supportable as periods of warm weather created some crusts and some harder layers in the snowpack. Unfortunately, even that "supportability" is going away as the snowpack continues to facet and weaken.

With limited terrain available for riding (low tide as some call it), take the time to practice with your rescue gear if you get out. Watch this video. Matt and Tom were glad they had practiced and luckily had a happy ending.

recent activity

No new avalanches have been reported in the Ogden area mountains.

Avalanche Problem 1
type aspect/elevation characteristics
over the next 24 hours

LOW danger doesn’t mean NO danger. Small avalanches can still be triggered in isolated places or radical terrain. The most likely place to trigger any of these slides would be on a steep, upper elevation northwest through northeasterly facing slope.

Watch for wind drifts following last week's NE winds. Also, watch for loose snow sluffs on steep slopes.

Otherwise the snowpack continues to weaken and facet on nearly all aspects except due south. This faceting isn't an avalnche problem until we get more snow to form a slab on top of it (video).


Sunny skies and warm temperatures in the mountains will continue through midweek and beyond. Temperatures each day will warm into the upper 30s to mid 40s, with the overnight low dipping into 20s. The northerly winds will average 5 to 15 mph, with the highest peaks averaging 20 to 25 mph.
