Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Saturday - January 23, 2016 - 7:20am
bottom line

The Avalanche Danger remains CONSIDERABLE on all steep, upper elevation slopes, especially those with new wind-drifts. Cautious route finding and conservative decision-making are essential today. Numerous close calls and avalanche fatalities in Utah and the western US this week emphasize the dangerous, complex snow pack and avalanche conditions.

Low angle, powder filled terrain choices are abundant in the northern Utah mountains and provide a safer choice.
special announcement

There are still spaces in the Women’s Backcountry 101 avalanche class at Brighton (Feb 4/6) and the Women’s Snowbasin Avalanche Awareness class Feb (18/20). For more info on those classes and other education offerings through out the state, check out our Education Page.

current conditions

Under partly cloudy skies, the southwesterly winds have increased into the 15 to 25 mph range. Speeds across the highest peaks (Mt Ogden) have averaged near 40 with gusts to near 50 for almost 24 hours. Temperatures are in the mid 20s to low 30s. The sunny slopes are crusted this morning, and may not soften much today. Dense powder can be found on the shady slopes, but it is punchy and inverted in places
recent activity

The updated Gobblers accident report was posted last night.

In the Ogden area mountains, there were reports of small, wet loose sluffs at the low and mid elevations, and wind drifts that could be released with slope cuts. The avalanche list has also been updated with more naturals activity from the January 20th slide cycle, and we’ll add more today.

description

One or more layers of faceted weak snow exist in the snow pack on upper elevation slopes and on some mid elevation slopes, especially those facing northwest through easterly. While this makes all steep, upper elevation slopes suspect, slopes that have only slid once this winter are prime suspects for avalanching again today, especially those with fresh wind drifts. Portions of the Ogden area mountains had a widespread avalanche cycle around Dec 21-23, especially on northerly facing slopes, and we haven't heard of any repeaters so far, which makes those slopes suspect.

Low elevation terrain: avoid terrain traps such as gullies, creek beds and large road banks where even a small slide could stack up and bury you.

Travel defensively today:

  • check slope angles today - bring your inclinometer or get an app on your phone
  • with faceted weak layers, a slope may not break out on the first person, but rather the 3rd or even 5th and slopes can be triggered from a distance
  • analyze the terrain – if you do get caught in a slide, where will you go – into trees, for a huge ride, off a cliff or into a gully? Is there a safer line?
  • Have someone in your group who will question decisions out loud, and initiate a discussion. Go with the conservative opinions.

The new winds slabs will add another problem to the more complex upper elevation snow pack. With southwesterly to westerly winds (later today), drifts will be most widespread on slopes facing north through east along the upper ridge lines. However, the terrain channels the wind, so watch for cross loading of drifts on other aspects and around features such as gully walls, sub ridges and slope break overs. Avoid these wind drifts on steep slopes.
weather

Clouds and winds will increase this morning, as an approaching storm enters northern Utah today. The southwesterly winds will average in the 15 to 25 mph range, with ridge lines averaging to 40 mph, with gusts to 50 mph. Ridge line temperatures will cool through out the day, to near 20 by evening. Light snowfall could start late this afternoon, but the heaviest snowfall will be tonight through about noon tomorrow. Winds will turn more northwesterly early Sunday morning, and snow showers will likely linger through the day Sunday before slowly tapering off Sunday night. Snow totals by Sunday night should be in the 6 to 12” range.

To get help in an emergency (to launch a rescue) in the Wasatch, call 911.  Be prepared to give your GPS coordinates or the run name. Dispatchers have a copy of the Wasatch Backcountry Ski map.

Backcountry Emergencies. It outlines your step-by-step method in the event of a winter backcountry incident.

If you trigger an avalanche in the backcountry, but no one is hurt and you do not need assistance, please notify the nearest ski area dispatch to avoid a needless response by rescue teams. Thanks.
