Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Friday - November 25, 2016 - 7:10am
bottom line

Most terrain still has a LOW danger in the Ogden area mountains. A MODERATE danger exists in steep wind-drifted terrain primarily in the upper elevations along the highest ridge lines, though look for and avoid any smaller drifts that develop in open bowls at the mid elevations. Getting caught even in a small slide can result in injury from hitting rocks due to the very 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. More info and links to the resorts here.

current conditions

Under clear skies, there is a slight temperature inversion in the mountains - the low elevations in the Ogden area mountains have temperatures near 20, while the mid elevations are in the low 30s. The southwesterly winds are averaging 15 to 20 mph, with the high Ogden ridge lines and peaks averaging 25 to 35 mph, with gusts to 45 mph.

The early season snow pack is still very shallow, and there really isn't enough snow to recreate yet in the Ogden area mountains unless you can get up very high. The sunny, southerly facing slopes are crusted. Approximate upper elevation snow depths through out the Wasatch:

  • Ogden area mountains - 6 to 16 inches at the mid to upper elevations
  • Provo area mountains – 4 to 8” at the low to mid elevations
  • Upper Cottonwoods – 18 to 24 inches
  • Park City side - about 12 – 18 inches

Today, new drifts of wind blown snow are the number one concern. There is snow available for transport, and the increasing southwesterly winds will drift snow both along the high ridge lines and down into mid slope open bowls. Plumes of snow blowing off the ridge lines and new cornices mean the wind is transporting snow. Shooting cracks in the snow indicate a sensitive wind slab, to be avoided on steep slopes.

description

The Ogden area mountains have a couple inches of weak faceted snow near the base of the snow pack, but this is limited to the highest, shady locations. It's possible that any new snow slide may step down into this older layering.

weather

High pressure will bring sunny skies and warm temperatures to the mountains today. 8,000’ temperatures will reach the low 40s, and ridge line temperatures will warm into the low 30s. The southwesterly winds will slowly increase today - by afternoon, averages to 20 mph will be common along most ridge lines, with the highest peaks averaging40 mph, with gusts in the 50s by evening. Saturday, look for increasing clouds and southwesterly winds, with the next storm slated for Saturday night into Sunday morning. Utah stays in the fast moving storm track, with more snow next week.
