Ogden Avalanche Advisory

Forecaster: Evelyn Lees


Discount Lift tickets: There are a few tickets left to Alta, Wolf Mountain, Sundance and Brian Head. Many thanks to Ski Utah, Backcountry.com and all the resorts that participated by donating tickets!

There is still space available in the next Backcountry 101 Avalanche Class. There is an evening session on January 6, with a field day on January 8th. Details at http://utahavalanchecenter.org/education

Danger Rose Tutorial

The avalanche danger is generally LEVEL 1 (LOW), with pockets of LEVEL 2 (MODERATE) danger for triggering a wind drift on steep slopes, with drifts most widespread on northeast, east and southeasterly facing slopes. There are also pockets of LEVEL 2 (MODERATE) for loose sluffs on steep, shady slopes.


Under clear skies to partly cloudy skies, temperatures are once again in the low teens and single digits this morning, with the warmer Ogden area mountains in the mid to upper teens. Along the high ridges, the west to northwesterly winds averaged in the 20 to 30 mph range overnight, with gusts reaching into the 30’s and 40’s. The sun and wind protected shady slopes are where the powder is, with other slopes sporting sun and wind crusts.


Yesterday, there was one new soft slab triggered, 8” deep by 20 feet wide, running on surface hoar, on an easterly facing slope at 9,500’. There were numerous reports from around the range of easily triggered loose sluffs in the weakening surface snow that are large and running far. And finally, reports of a few isolated pockets of wind slab along the high Ogden area mountain ridgelines. Check Current Conditions and Avalanche List for photos of some of the large avalanches from last week’s cycle.


      Over the next 12 hours.

With winds kicking up once again along the high ridgelines, watch out for and avoid the new drifts of windblown snow. Some of these drifts are landing on weak snow, including surface hoar, and may be quite sensitive. Wind drifts are rounded and pillowy deposits of snow, and will be most common today on slopes with an easterly facing component.


      Over the next 24 hours.

The surface snow is weakening, and reports of surface hoar (check out surface hoar in the Avalanche Encyclopedia) are becoming more widespread. Loose snow sluffs are getting larger and running further in continuously steep terrain. While careful slope cuts are a good defense, use caution in terrain with higher consequences, such as when getting caught could take you off a cliff, into trees or for a long ride.


Another weak system in the northwest flow will cross northern Utah today and tonight, bringing a chance for a trace to a couple inches of snow. Clouds are rapidly increasing this morning, and the west to northwesterly winds will kick up a bit today, with 30 to 40 mph averages and gusts to 60 possible along the highest ridges. Elsewhere, 10 to 20 mph averages, with gusts to 30, will be more common. Temperatures will warm into the upper 20’s at 8,000’, and to near 20 along the high ridges. High pressure on Thursday and Friday will be followed by a nice cold storm on Saturday with a decent shot of snow possible.


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.

Ogden – Snowbasin Patrol Dispatch (801-620-1017)
