Avalanche Advisory
| Advisory: Ogden Area Mountains | Issued by Brett Kobernik for January 24, 2013 - 6:50am |

Above 8,500 ft.
7,000-8,500 ft.
Below 7,000 ft.

bottom line While most of the terrain still has a LOW avalanche danger, there is a pockety MODERATE avalanche danger along mid and upper elevation ridgelines and terrain features with recent deposits of wind blown snow. You'll find these mostly on the north half of the compass. There may be the chance of some wet avalanche activity on all aspects in the 6500 to 8500 foot range today as well.

current conditions Moderate speed southwest winds over the last 24 hours headline today's avalanche advisory. We are still seeing some stronger gusts along the more exposed terrain with continued moderate speeds along the mid elevation ridges. Temperatures remain very warm with readings above 40 at the 7000 foot level and above freezing at the 9000 foot level. These warm temperatures have persisted for over 24 hours. There are reports of light snow as of 6am. |

recent activity The warm temperatures and recent winds produced some scattered avalanche There was also some small natural wet loose snow avalanches reported from the mid elevations caused by the warm temperatures just above the cold valley inversions. There was some activity reported from the North Fork area of Provo Canyon as well as some dribblers coming from above the Great White Icicle onto some climbers in Little Cottonwood Canyon that gave them a slight scare.

Wind slabs are almost always the most sensitive during and just after they form so I suspect yesterday's will be a bit more stubborn today. However, we are expecting a little shot of snow and with continued moderate speed winds, perhaps some fresh drifts will form again today. Slope cuts are excellent tools to use prior to diving into any steep leeward slope. |

Temperatures are not expected to get as warm today as yesterday so I'd expect that will put a cap on the natural wet loose snow avalanches but I'm still mentioning them. The snow is most likely still quite damp but it may take a person disturbing it to get anything to move. Nonetheless, stay out of the bottom of steep gullies and avalanche tracks where loose snow avalanches may funnel into including all of the steep mid elevation couloirs. Ice climbs may not be the best choice today. |

weather A quick hitting cold front will give us a shot of snow today and I'm thinking we'll see an average in the 2 to 6 inch range. Moderate southwest winds will continue through the day with stronger gusts along the ridges. Ridgetop temperatures should cool into the 20s as the day progresses. High pressure briefly returns Friday and Saturday and perhaps a better looking storm is shaping up to start on Sunday. |
