Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Mark Staples for Thursday - January 28, 2016 - 5:55am
bottom line

Today the avalanche danger remains CONSIDERABLE at the upper elevations on NW through N through E facing slopes where dangerous avalanche conditions exist. There are buried persistent weak layers of faceted snow which are tricky to assess but have been producing avalanches through much of January. Avalanches are the clearest sign of unstable conditions. Also watch for wet loose avalanches on more southerly facing slopes where the snow surface will become wet.

Safe terrain is any slope less than 30 degrees in steepness. Many of these low angle slopes have great coverage and great snow on sun and wind sheltered terrain.

current conditions

Yesterday felt hot with strong sunshine, calm winds, and clear skies. High temperatures yesterday reached 40 degrees F. Snow on south aspects got wet on the surface. Slopes shaded from the sun remained cool and had great riding conditions with soft, settled powder. This morning temperatures are near 30 degrees F with some valley temperatures in the teens F. Light winds are blowing 5 mph.

recent activity

In the last three weeks, there have only been four days without avalanche activity involving faceted layers of snow. The most recent spike in these persistent slab avalanches occurred on January 20th and 21st including a fatal one on Gobblers Knob. This avalanche activity occurred on almost all aspects in elevations above 8000 feet. View a list of all the avalanche activity here where you can sort by region and date.

Yesterday there were many wet loose avalanches on southerly aspects. Many of these started in rocky areas as the snow surface became wet.

The most notable persistent slab avalanche was triggered someone heli-skiing in Cardiff Fork on a northwest facing run at 10,200 feet called Holy Toledo. The skier was the 15th person to ski the slope when it avalanched. He was carried 350 vertical feet and sustained significant injuries when the avalanche slammed him into a tree. The avalanche broke on facets on or near the ground 1 to 4.5 feet deep. Photo - M. White

Faceted layers of snow that can produce a persistent slab avalanche exist mostly on NW through N through E facing slopes at upper elevations.The good news is that there has been minimal avalanche activity in the Ogden are mountains. The most likely place to trigger an avalanche is on slopes that previously avalanched near the ground. We call these slopes "repeaters" because they either have or will produce more avalanches this season. Mid elevation slopes in the Ogden area mountains and slopes at other elevations that haven't avalanched are developing a deep, stronger snowpack.

A few wind slabs remain that can be triggered. The reason is that some may be resting on facets which keep them unstable. Guides ski cut a small wind slab yesterday in the upper part of Mineral Fork.

weather

Today will be mostly sunny with more calm winds and strong sunshine until clouds enter the area late today. Temperatures should climb into the upper 30s and low 40s F. A major storm is approaching with snowfall starting late Friday.
