Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Drew Hardesty for Thursday - November 24, 2016 - 7:15am
bottom line

Most terrain still has a Low danger. A Moderate danger exists in steep wind-drifted terrain primarily in the upper elevations. Remember that we often have early season accidents and involvements as powder-fever tends to over-rule rational, conservative decision-making. Remember that the traumatic injury is likely with any incident due to the still-thin coverage.




special announcement

Generally speaking, if you're heading to a ski area please check in with the individual ski resort and find out their uphill traffic policies. If you walk up one ski area with another adjacent to it, please respect and check in with the sister resort before riding down into their resort. More info and links to the resorts here.

current conditions

This storm was no turkey. (Sorry about that.) The cold front moved in like a freight train around dinnertime last night with storm totals in the 4-6" range. 12-18" of snow sit in in the upper elevations allowing for fair, if tentative, travel. Mind the still thinly veiled rocks, stumps, and deadfall.

Skies are clearing. Temps have plummeted to the teens up high, the low 20s down low. Gustiest during and just after frontal passage, the west-northwest winds are now generally less than 15mph on both Mt. Ogden and James Peak.

New wind drifts up to a foot are possible in the highest terrain and likely sensitive to the weight of a person. Look for and avoid any smooth, rounded snow feature in steeper terrain.

Hot Tip - Cracking and collapsing are sure signs of localized instability.

Note: conditions will likely improve as the day wears on.

Yesterday, I triggered a wind slab in the upper Cottonwoods. Interesting to note that yesterday's hard wind slab remained within the new snow and did not step down into the older underlying weak faceted snow near the ground. The Ogden area mountains have a couple inches of weak faceted snow near the base of the snowpack, but this is limited to the highest, shady locations. It's possible that any new snow slide may step down into this older layering. Photo from Alta, below, as an example, though the Ogden snowpack is about half of this.

weather

We'll have clearing skies, mountain temps in the low 20s, and 15mph winds from the west and northwest. Ridging moves in, albeit briefly, ahead of another large scale storm impacting the intermountain west starting late Saturday through Tuesday. It looks to be a southern Utah special, but we may potentially see another decent foot of snow over that time period. In the meantime, temps will warm toward freezing up high later tomorrow with increasing southwest to south winds tomorrow through Saturday.
