Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Saturday - November 28, 2015 - 7:05am
bottom line

The avalanche danger is generally LOW today; there is an isolated MODERATE danger along the high ridge lines for scattered wind drifts, which could be triggered in steep terrain. The shallow snow pack makes getting caught in even a small slide dangerous, as you would get dragged along the ground, scrapping rocks.

current conditions

Under cloudy skies and scattered snow flurries, temperatures are in the single digits this morning, with a few stations struggling into the low teens. Overnight, most locations picked up a trace of low-density snow, with 2 inches in the Provo area mountains and upper Cottonwoods. The wind direction is variable and speeds very low – averaging 5 to 10 mph, and less than 20 mph even across the highest peaks in the Ogden area mountains. The shallow snow pack is less than 1 1/2 feet deep in the Ogden area mountains, and hitting rocks and logs is likely on many slopes. I spent time in the Ogden area mountains yesterday, and found a very shallow and weak snow pack. Observation HERE.

recent activity

There was one intentionally triggered wind slab yesterday, which quickly stepped down to the weak facets on the ground. It was on a steep, northerly facing slope along the Silver Fork ridge line in the Salt Lake area mountains – 10 inches deep by 30’ wide. Mark White photo below, complete observation HERE.

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

Our weak snowpack just can’t handle much. The shallow wind drifts created by just a few hours of faster wind speeds yesterday were sensitive and cracky. If you get one of these drifts moving, it’s likely to break down to the ground. Yesterday’s drifts were isolated to the ridgelines, where the winds blew the strongest. Again today, watch for any cracking in denser snow layers, and avoid these drifts on steep slopes. While on a variety of aspects, they are mostly likely to step to the ground on northwest through easterly facing slopes.


Skies will be mostly cloudy through Sunday night, with intermittent light snowfall. A trace to a few inches of low-density fluff is possible today and again tonight, especially north of I-80. Wind speeds are forecast to remain very light for the next 24 hours – generally less than 5 mph, with the highest peaks occasionally reaching 15 mph averages. 10,000’ temperatures will struggle to get out of the single digits, 8,000’ temperatures will warm into the teens. Sunday afternoon, there will be a shift to a moist northwest flow, which could bring a few more inches of snow. This will be followed by another dry looking week.
