Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Sunday - November 30, 2014 - 7:16am
bottom line

The avalanche danger is MODERATE in the Ogden area mountains. Also avoid any steep slope with fresh drifts of wind-blown snow, and check out the bonding of the new snow to the old. Be aware that the old snow sitting on the ground has weakened on the northerly facing slopes, and if the snow piles up more than expected, it will become sensitive.

special announcement

On December 4, Powderwhore Productions will be bringing Some Thing Else to Park City. A fundraising raffle will be held to benefit the Utah Avalanche Center. Details here.

current conditions

A weak cold front will bring light snow, cooling temperatures and decreasing wind speeds to the mountains today. The front has passes the Ogden area mountains, and temperatures have cooled into the 20s and are still dropping; the winds are shifting to a more westerly direction, and have decreased into the 10 to 15 mph range, with the high peaks averaging 25 to 35. Soft snow is hard to find among the hard wind slabs and sun crusts. Access to the upper elevations remains a challenge due to low snow.

recent activity

A slide was triggered remotely from a distance yesterday in the northwest facing Birthday Chutes of Little Cottonwood Canyon – about 2.5’ deep, 60’ wide, and far running, scooping up all the snow in its path. It was at 10,500’ and failed on faceted snow on the ground. Observation posted HERE.

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

There are the usual avalanche problems to be aware of in all terrain, especially upper elevation terrain:

  • Avoid any wind drifts. Old, hard wind drifts are widespread at the upper elevations, and new soft drifts may form along the high ridges later this afternoon as the new snow adds up.
  • The new snow may bond poorly to the hard wind slabs and slick sun crusts, and shallow sluffs and cracky soft slabs may develop.
  • There could be some lingering damp, punchy snow to be avoided on mid and low elevation northerly facing slopes, until the snowpack cools.
  • There is some faceted snow on upper elevation, shady slopes that could become a weak layer when it finally gets over loaded with snow. Collapsing and cracking are signs that the facets are becoming overloaded.

To see where slides have been triggered by elevation and aspect, Kobernik created a “make your own avalanche rose” HERE – just choose your dates.


There will be periods of light snow today through the night as a weak cold front stalls over northern Utah. 3 to 6” of new snow is possible. 10,000’ temperatures will be in the low 20s, and 8,000’ temperatures in the mid-30s. The rain-snow line will be around 6,000’. Winds will remain from the west southwest, with averages in the 5 to 15 mph range. Wind speeds across the highest ridgelines will occasionally average 35 mph, and gust into the 40s. There will be a break on Monday, followed by another warm storm Tuesday night into Wednesday.

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.
