Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Wednesday - November 27, 2013 - 6:47am
bottom line

There is a mostly LOW avalanche danger, with pockets of MODERATE avalanche danger on steep, northwest, north and northeasterly facing slopes where there is wind drifted snow over facets. In isolated places at the upper elevations, a person could trigger a slide, and any ride would be rocky and rough.

This avalanche advisory will cover both today and Thursday with our next advisory Friday morning.

current conditions

Another beautiful day in the mountains – mostly clear skies, with temperatures right around freezing this morning. The southwesterly winds are light, averaging less than 10 mph, at just about every mountain weather station but those in Ogden area mountains, where speeds across the high ridges are averaging closer to 20 mph.

The snowpack remains very shallow, with few options for easy backcountry travel. Even some of the early season “classic” places to go are rock studded, and the lower elevations and sunny slopes are melting down to dirt. Still, there are a few nice pockets of soft snow on upper elevation, shady slopes, and the groomers at the resorts are an excellent choice for early season turns and clean air.

recent activity

The most recent reported avalanche activity was from Monday - resort avalanche reduction work in Little Cottonwood triggered several medium sized hard slab avalanches on wind loaded northeasterly facing slopes, failing on facets. Looking at the Avalanche List, there have been no reported backcountry avalanches since November 17th in the Wasatch mountains.

description

Wind slabs over facets remain the main concern. There are spotty places where a person could trigger one of these dense or hard wind drifts, mostly on northwest, north or northeasterly facing slopes. These drifts could be right along the ridgelines or mid slopes, and avoid the hard drifts on any steep slope.

My field work yesterday showed an overall weakening snowpack – and the shallower the snowpack, the weaker. If you’re out and about, look for the pattern of sugary loose snow - on the surface, beneath the wind crusts and wind board, near the ground and in shallow snowpack areas…the whole snowpack.

weather

The quiet weather week continues… A slight shift in the ridge axis will allow a few high thin clouds to move overhead today and a very light southerly flow to develop. High temperatures will be in the mid-30s to mid- 40s today, and then drop to near freezing again tonight. Partly cloudy skies and mild temperatures will continue into Sunday, with a few snow flurries possible Saturday evening. Then there is hope on the horizon for a return to winter, with a strong cold front in the forecast for Monday night.

general announcements

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.
