BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

The avalanche danger is generally LEVEL 1 (LOW), with pockets of LEVEL 2 (MODERATE) danger for triggering hard wind drifts on steep slopes. There are also pockets of LEVEL 2 (MODERATE) for wet loose avalanches if the snow gets damp on steep, sunny slopes and low elevation shady slopes.


CURRENT CONDITIONS

Under clear skies, it is a chilly start to the day, with temperatures in the low teens and single digits this morning. The westerly winds are light, less than 15 mph, except for the highest peaks and the Ogden area ridgelines, which are averaging 25 mph, gusting to 30. Wind sheltered, shady slopes still harbor excellent light powder snow, with the sunny slopes crusted and old wind damage along high ridges and in open bowls.


RECENT ACTIVITY

It was another day very quiet day in the backcountry, with no new avalanches reported. However, sightseeing continues, with reports still coming in of large avalanche crowns from the avalanche cycle last week.


THREAT #1

It was another day very quiet day in the backcountry, with no new avalanches reported. However, sightseeing continues, with reports still coming in of large avalanche crowns from the avalanche cycle last week.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 10 hours.

It will be a clear, sunny morning followed by high, thin clouds moving in. This may be just enough to heat up the surface snow on the steep southeast through westerly facing slopes. Once the snow is damp, it will be possible to trigger loose snow sluffs, and there is still the isolated possibility of a slab releasing, running on the buried sun crust. High thin clouds could even dampen some of the snow on low to mid northerly facing slopes.


MOUNTAIN WEATHER

Northern Utah will be under a northwest flow today through Thursday, with weak disturbances bringing occasional cloudy skies and a chance of isolated snow flurries. Clouds will increase this afternoon ahead of the first weak disturbance, and there will be a chance for a snow flurry or two, with accumulations less than an inch. The winds will shift to the northwest, and speeds will gradually increase along the high ridges, into the 20 to 30 mph range, with gusts to 45, late this afternoon through early tomorrow morning. Temperatures will warm into the mid 20’s once again at the 8 to 10,000’ level. The models are now advertizing a strong cold front for Saturday afternoon followed by a cold moist northwest flow that lasts into Monday.
