| Advisory: Provo Area Mountains | Issued by Brett Kobernik for Monday - January 13, 2014 - 7:26am |

|
bottom line Very dangerous avalanche conditions continue through today. There is a CONSIDERABLE overall avalanche danger. Large human triggered avalanches are likely. Pay attention to what is uphill of you as you may trigger an avalanche from below. It is wise to avoid all steep wind loaded slopes again today.

avalanche warning THIS AVALANCHE WARNING IS FOR THE MOUNTAINS OF NORTHERN AND CENTRAL UTAH, TO INCLUDE THE WESTERN UINTA MOUNTAINS. VERY DANGEROUS AVALANCHE CONDITIONS EXIST THROUGH TODAY...AVOID BEING ON OR BENEATH STEEP MOUNTAIN SLOPES...AS AVALANCHES MAY BE TRIGGERED LOW ON THE SLOPE AS WELL.

current conditions The wind continues. The wind is generally from the west and perhaps just slightly slower than on Sunday. Temperatures are in the upper teens. The Provo area mountains didn't pick up any new snow in the last 24 hours. Out of the wind, riding conditions are excellent. |
 |
recent activity No avalanches were reported from Sunday in the Provo area mountains. Keep in mind that poor visibility didn't allow us to look into areas that likely had natural avalanche activity. The blowing and drifting snow also kept people off the ridges or out of the backcountry all together. So, we don't have much information from Sunday aside from the fact that it snowed and the wind drifted the new snow. We also know that there is an abundance of buried weak faceted snow where many of these fresh slabs are forming. |

description
An avalanche breaking into old weak sugary faceted snow is by far the biggest danger out there today. This is an 'unmanageable' situation. Ski cuts are ineffective. Don't rely on stability tests. All you need to know is we've just recently added a bunch of weight to our buried weak layers and this is when they are most likely to collapse and cause an avalanche. Getting onto steep slopes that have received a bunch of new snow and wind loading is a roll of the dice. |

The fresh wind slabs on their own will most likely be more stubborn today than Sunday. They will be larger though. Obviously, they are most pronounced on east facing slopes since the westerly winds have been loading snow from the west to east. However, keep in mind that wind direction varies greatly with terrain and many features will have crossloaded areas on all aspects. |

Same deal for the fresh cornices as the wind slabs. They will probably be more stubborn but larger than on Sunday. Do not approach these cornices as they often break back farther than we anticipate. |
 |
weather Annoying westerly winds will continue with strong gusts along the upper ridges. Temperatures should get into the mid 20s. We'll most likely see cloud cover through today. Winds veer north and continue on Tuesday but slow slightly. The ridge of high pressure again sets up over the coast giving mild weather as the week continues. |
