Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Tuesday - January 3, 2017 - 7:21am
bottom line

The avalanche danger is MODERATE today on steep, wind drifted slopes at the mid and upper elevations. MODERATE means human triggered slides are possible. If winds speeds increase where you are, the avalanche danger will also increase on the wind-drifted slopes. Out of the wind-affected terrain, the avalanche danger will remain LOW to MODERATE. The most likely place to trigger a shallow new snow slab or sluff would be on a steep, northwest through easterly facing slope.

If you head through a gate or out-of-bounds from a ski resort, you are in the backcountry and in avalanche terrain. You need to be prepared with a beacon, shovel and probe, and the avalanche education to use them and to evaluate the snowpack and terrain. There are LOTS of avalanche classes in the Ogden area mountains this month.

The new wind slabs will still be sensitive today, most widespread in upper elevation terrain. If the wind speeds increase where you are, sensitive drifts will rapidly develop and human triggered slides will be likely on steep slopes. ‚Äč Use small test slopes to gauge the sensitivity of the wind drifts.

Even out of the wind-affected terrain, the new snow will bond poorly to some of the old snow surfaces, though well to others. Be prepared to trigger new snow sluffs and shallow soft slabs on steep slopes , especially on sheltered, shady slopes.

Any of the buried faceted weak layers should still be dormant, but a smaller new snow slide might be able to trigger a deeper slide in the snowpack, especially in a shallower snowpack area. These weak layers can be found around the compass, including some southerly facing slopes with facet-crust sandwiches., and mostly at the upper elevations. They also exist at the mid elevations in the Ogden area mountains around the buried rain crusts.

weather

Skies will be mostly cloudy today, with a few snow flurries possible this morning. Temperatures will warm into the low 20s at 8,000’, and mid-teens along the high ridge lines. The southwesterly winds will be light at the mid elevations, averaging 10 to 15 mph. Across the higher terrain, wind speeds could increase to 25 to 35 mph with gusts in the 40s and 50s.

The next storm will arrive by tomorrow morning, lasting into Thursday morning, with increasing temperatures, wind and heavy dense snow.
