Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Thursday - February 12, 2015 - 6:42am
bottom line

The avalanche danger is LOW this morning, and avalanches are unlikely. As the day and snow heats up, the danger will increase to MODERATE on steep, sunny slopes, where it will become possible to trigger small, damp loose sluffs. If you are heading to the Logan area mountains or the Western Uintas, check out their area specific forecasts, as the danger is higher in these regions.
special announcement

Join us February 19th and 21st for a Women's Intro to Avalanches at Snowbasin. Learn how to travel safely in avalanche terrain. This workshop begins with a three hour evening class in Ogden, followed by a 6 hour on-the-snow field day. Taught by Paige Pagnucco, Evelyn Lees and several others from the Utah Avalanche Center and members of Snowbasin Ski Patrol. Space is limited. Sign up HERE.
current conditions

Skies vary from clear to partly cloudy this morning, as bands of high thin clouds move across northern Utah. Temperatures are in the mid-twenties to low 30s and winds are from a westerly direction. Most stations are averaging less than 10 miles per hour, with only a few of the highest peaks registering average speeds of 30 mph, with gusts to 35.

Turning and riding conditions are very good in dry, soft snow on upper elevation, northwest through northeasterly facing slopes. Most other aspects and the lower elevations have a variety of crusts, which will soften with day time heating. The low elevation snowpack has taken a hit, and approaches and exits are rocky to downright difficult, especially in the Provo and Ogden area mountains.
recent activity

The only reports were of minor dry and wet loose sluffs and some very localized cracking in wind drifts that didn’t move.

description

The avalanche danger is generally low, and significant avalanches are unlikely. However, a variety of small avalanches are possible, just large enough to catch and carry a person on foot in steep terrain.

  • Warm temperatures combined with periods of direct sun will heat the snow, and people will be able to trigger shallow, wet loose sluffs on steep slopes. These may be large enough to warrant a pockety Moderated danger in the heat of the day. The snow on mid-elevation shady slopes may also become damp enough to sluff.
  • Small dry loose sluffs can be triggered on steep, shady slopes
  • Cornices are sensitive, and they could break back further than expected or even on approach.
  • Isolated, small wind drifts along the higher ridge lines, could crack out beneath you.
weather

It will be another spring like day, with temperatures warming into the upper 30s along the high ridge lines, and into the mid-40s at 8,000’. The winds will remain from a westerly direction, and generally average less than 10 mph. Only a few of the highest peaks and ridges will have speeds reaching 25 to 30 mph. Abundant high thin clouds will stream over the area, though periods of direct sun may become more common this afternoon. Friday will be similar, though with fewer clouds and slightly warmer temperatures. Cooler air is in the future – a cold front Monday could bring a few inches of snow and temperatures in the teens.
