Avalanche Advisory
| Advisory: Provo Area Mountains | Issued by Brett Kobernik for December 27, 2012 - 7:15am |

Above 9,500 ft.
8,000-9,500 ft.
Below 8,000 ft.

bottom line There is a CONSIDERABLE avalanche danger today. Experience along with careful route finding procedures and following safe backcountry protocol is a must today. If you don't fully understand what that statement includes then you should avoid being on or below any slopes over around 30 degrees in steepness.

special announcement Little Cottonwood Canyon is closed for avalanche control work. Estimated re-opening is 8:30am. We will update through Twitter later this morning with any significant avalanche control results. |
 |
current conditions The current storm is verifying quite nicely in my opinion with around a foot of new snow or better in the Cottonwoods containing around ¾” of water with the mid portions of the canyons doing very well. The Provo area mountains got clobbered with 2 feet of snow and the Ogden area is doing quite well with 20” or so up there. Temperatures are in the teens and winds are fairly light from a westerly direction with some moderate speed gusts along the higher terrain. |
 |
recent activity Natural avalanche activity is occurring in the Provo area mountains. There is no doubt that the new 2 feet of snow is sensitive and we suspect that we'll see evidence of larger avalanches that have broke into older snow in the upper elevation northerly facing slopes. |

We're going to keep it simple today people. The new snow is not manageable for backcountry travelers in the Provo area avalanche terrain which includes all slopes of 30 degrees or steeper. It is best to let it settle today and see how it's behaving once the storm passes. If you are venturing out, stay off of and out from under any steep avalanche paths. |

The wise backcountry traveler will have patience with the thinner snowpack areas today and let the dust settle before venturing into steep slopes with old weaker snow. I would be surprised if some of the older layers haven't already failed and produced natural avalanches. It is no time to toy with any steep northerly facing slopes in the Provo area mountains. |

weather We should see periods of snow today which should taper off somewhat mid day. We should see a few more inches of snow in the Provo region. Temperatures should remain in the teens and winds should remain fairly light switching more northerly as the day progresses. There is one last wave that may produce a few more snow showers just before this system completely exits our area by Friday. |
