Avalanche Advisory
Advisory: Provo Area Mountains Issued by Evelyn Lees for Sunday - November 23, 2014 - 7:12am
bottom line

The avalanche danger is HIGH on upper elevation slopes facing northwest through north through southeast, where the snow is landing on the old, weak sugary facets. A CONSIDERABLE avalanche danger exists on steep mid elevation slopes, facing northwest through north through east. AVOID travel on and below these slopes, as it is possible to trigger slides remotely from a distance and from below. Taking a ride in an early season avalanche is particularly dangerous, as the chance of hitting a rock is high. If you do choose to head out today, choose slopes gentler than 30 degrees in steepness with nothing above.




avalanche warning

The Avalanche Warning for all the mountains of northern Utah has been continued.   Dangerous avalanche conditions exist at the mid and upper elevations, with both natural and human triggered slides likely.  This warning does not include ski areas or highways where avalanche control is normally done.

current conditions

Light to moderate snow is falling this morning, as another piece of the storm drops south along the Wasatch mountains.

  • Storm totals: as of 6 am are 10 to 16” of snow in the Cottonwoods and on the Park City side and 6-10” in the Ogden and Provo area mountains. Water equivalent: 1 to 1.8”
  • Winds: were very strong overnight across the higher terrain from the west to northwest, with the high peaks averaging in the 40s and 50s, with gusts in the 70s. At the mid elevations, speeds have been 15 to 25 mph, gusting to 40.
  • Temperatures: are in the teens to low 20s.
recent activity

Some natural activity was reported from the Cottonwoods overnight, and a few small wind pockets popped out yesterday on steep low elevation terrain in the Park City mountains. There were no observations from the backcountry yesterday.

The winds tipped the balance overnight, helping overload the slopes with old, sugary snow on the ground. Prime terrain for avalanches toady are upper elevation slopes, facing west through north through southeast, especially where wind drifted. The wind drifted snow will be both along the ridgelines and mid slope, piled up along sub ridges, break overs, and the sides of gullies. Many shadier mid elevation slopes also had weak, sugary snow sitting on the ground, and it will be possible to trigger avalanches on steep slopes in this terrain too. Avalanches today can be triggered remotely from a distance – avoid travel below and adjacent to steep slopes.

You will find wind drifts scattered all over – on a variety of elevations and aspects. You will be most likely to trigger a drift where it is sitting on sugary old snow, but drifts should be avoided on all steep slopes.

weather

Light to moderate snowfall will continue for a few more hours this morning, before there is a significant break in the snow through this evening. Skies will remain mostly cloudy today, and temperatures won’t warm much – remaining in the teens and low 20s. The northwesterly winds are decreasing, and should be in the 10 to 20 mph range at most locations by this afternoon, with the highest peaks averaging to 30 mph, with gusts to 50. One last piece of the storm should arrive after midnight, bringing an additional 4 to 8” of snow by Monday afternoon. The beginning of next week looks quiet.
