Forecast for the Salt Lake Area Mountains

Issued by Brett Kobernik for
Friday, February 8, 2013

A MODERATE avalanche danger remains on the mid and upper elevation northerly and east facing slopes. Human triggered avalanches are possible. Southerly winds may have created some fresh sensitive drifts along the ridges and could enhance the chance of triggering an avalanche that breaks into old weak snow.

Weather and Snow

Temperatures are a bit warmer than 24 hours ago but still dipped into the teens in the higher terrain. As anticipated, the southerly winds picked up and are blowing in the moderate category with stronger gusts. The snow surface is a mixed bag of soft settled snow, wind crusts and sun crusts depending on aspect, elevation and slope angle.

Description

The recent winds may have changed the avalanche conditions over the last 12 hours by creating fresh drifts. I suspect any of these will be somewhat stubborn which can be misleading when they aren't reacting to prodding. Continue to use slope cuts prior to diving into any steep terrain. Don't trust any fresh drift especially in committing terrain such as above rocks or cliffs as well as having trees below.

  • Persistent Slabs: If you're getting into radical terrain with slope angles pushing 40 degrees on the more northerly and east aspects there's still a chance you could produce an avalanche that breaks into older weak snow. The recent winds could enhance this concern by adding additional weight in the form of a fresh drift.
Additional Information

Southerly winds will continue in the moderate speed category with some stronger gusts for most of the day. Ridgetop temperatures will get into the 20s. A storm is at our doorstep and should start to produce snowfall this afternoon with a good shot coming in a southwest flow tonight into Saturday. As the system gradually moves through, the flow will change to a northwest flow where we should see more accumulations Saturday night into Sunday. The storm lingers into Monday. It looks fairly cold and winds don't look like they'll ever get out of hand. The new snow should fall right side up, that is, densities decreasing as the storm progresses. I'm anticipating about a foot of snow and an inch of water. There is the distinct possibility some areas will do much better. This has the potential to be a real good storm for backcountry enthusiasts.
