Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Saturday - April 9, 2016 - 6:51am
bottom line

The avalanche danger is MODERATE today at the low and mid elevations in the Ogden area mountains, where wet loose sluffs could be triggered. There is also an isolated chance of triggering a wet slab avalanche or having a glide avalanche release.

special announcement

End of the season: Sunday, April 10th, will be our last regular early morning up date for the 2015-2016 winter season. We will continue to do weather-dependent intermittent updates through the month of April, and continue to post your observations on a daily basis. Your observations will become increasingly important to the backcountry community.

Today and tomorrow is Adventure Gear Expo, Utah’s largest interactive adventure festival and outdoor gear sale for the public, at the South Town Expo Center in Sandy highlighting 100+ local and national retailers, manufacturers and non-profits in active outdoor sports, outdoor photography and adventure travel. If you buy tickets online using the promo code GOUAC, you will get a $2 discount and they will donate $2 to the UAC.

current conditions

Under partly cloudy skies, ridge line temperatures in the Ogden area mountains are in the low 30s, about 3 to 6 degrees cooler than yesterday morning. Low elevation to mid temperatures are warmer though, in the 40s. Winds are from the southwest, and averaging 15 to 25 mph, with gusts to 35 mph. There should be a good refreeze of the snow surface at the upper elevations, and beware of slipping and going for a long ride on the hard icy surfaces.

recent activity

There was a report of collapsing Thursday of the thin melt freeze crust on Cutler Ridge, continuing a trend of collapsing this week. Also, earlier this week, large glide avalanches released in Stairs and Broads Fork in Big Cottonwood Canyon and glide cracks have been reported from low in Cutler Basin. Here are the most recent observations from the Ogden area mountains.

type aspect/elevation characteristics
over the next 24 hours

It may be possible to trigger a wet sluff today on steep low to mid elevation slopes, especially on the northerly facing and treed slopes, which had a poor to no overnight refreeze. Reports from yesterday included the snow being absolute much below 8,000' by noon and skier triggered roller balls below 8,000'. Clouds and wind should help keep the snow pack cool at the upper elevations today.

Even with LOW danger for other issues, travel in snow covered alpine terrain always has some risk….

There is an isolated chance of triggering a wet slab avalanche, where a frozen crust fails on wet snow beneath. Any collapsing or bending of the crust where you are means poor layering, and time to get off steep slopes.

Glide avalanches continue to be a wild card – occurring where smooth rock slabs underlie the snow pack. Release is random, so avoid travel below any glide cracks.


A series of weak storm systems moving across the desert southwest will bring scattered rain and snow showers to northern Utah this afternoon into the night, with a 20% chance of lightning. Skies will be partly to mostly cloudy today, with 10,000’ temperatures in the low to mid 30s and 8000’ temperatures in the upper 40s. This puts the rain/snow line between 9 and 10,000’, though only a trace to 2” of snow is expected. The southerly winds will average 10 to 20 mph, with gusts in the 30 to 35 mph range. Temperatures will be slightly cooler Sunday, with the chance of rain and snow showers more isolated.
