| Advisory: Ogden Area Mountains | Issued by Evelyn Lees for Saturday - January 3, 2015 - 7:03am |
|---|

bottom line The avalanche danger is MODERATE on any steep slope with fresh drifts of wind-blown snow. These sensitive drifts will be most common on upper elevation slopes facing northeast through southeast, but could occur in any upper elevation terrain. The danger is also MODERATE for the isolated chance of triggering a deeper slide breaking on a buried weak layer of faceted snow. This poor snow pack structure is most widespread on upper elevation slopes facing northwest through east.

current conditions Skies are mostly cloudy, and temperatures are in the teens and low twenties in the Ogden area mountains. The weak cold front passing over the area has also kicked up the westerly winds across the highest peaks since midnight, with average speeds of 25 to 35 mph, and gusts to about 40 mph. Once you drop below the high elevation wind zone, average wind speeds are much more civilized at 15 mph, with occasional gusts to 30. Strong winds over the past week have stripped the snow down to the rain/rime ice crust on exposed slopes. Your best bet for some shallow powder would be on shady, wind sheltered slopes. |

recent activity The only avalanches reported from the backcountry yesterday were a couple very small wet loose sluffs from mid-day heating on mid elevation, south facing slopes. Here are the Ogden area observations since Christmas:

description
A new batch of cracky wind slabs will be created today along the highest ridges and peaks. With westerly winds, these drifts will be most common on the east ½ of the compass. However, the winds are channeled by the terrain, and can pile snow drifts onto other aspects at the highest elevations. The wind speeds are not expected to increase at the mid elevations today, but if they do where you are, watch for and avoid any fresh wind drifts. |

It is a wild card, but there is still an isolated place or two where a deeper slide could be triggered in upper elevation terrain facing northwest through east, especially if it gets freshly wind loaded today. Slopes with a poor snow structure and a shallower snowpack are most suspect. An example of poor structure in the "Cutler Ridge lasagna" (Tim Beaman profile).

weather A shallow cold front will bring increased winds and a chance for light snow today, with accumulations of only a trace to an inch. The west to northwesterly winds will generally be in the 10 to 15 mph, with gusts to 30. But along the highest ridgelines they will crank for most of the day – 35 to 45 mph averages at times, with gusts to 65. Temperatures will be in the teens to low 20s today. Partly cloudy skies tonight, with winds decreasing slightly. Sunday through Tuesday, a moist northwest flow will set up across northwest Utah, with warming temperatures and occasional light snow. |
| general announcements Remember your information can save lives. If you see anything we should know about, please participate in the creation of our own community avalanche advisory by submitting snow and avalanche conditions. You can also call us at 801-524-5304, email by clicking HERE, or include #utavy in your tweet or Instagram. 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.
