Advisory: Logan Area Mountains | Issued by Toby Weed for Monday - February 24, 2014 - 7:22am |

current conditions The interior of the Central Bear River Range picked up a pretty good shot of snow on Saturday morning, with 13 inches of accumulation recorded in 6 hrs at the Tony Grove Snotel. It's a balmy 33 degrees at 8400' and there's 103 inches of total snow, containing 120% of average water content for the date. The 9700' CSI Logan Peak weather station reports 25 degrees and average wind speeds in the mid twenties from the west southwest again this morning. You can find good powder riding conditions, especially on sheltered shady slopes, but yesterday's sun damaged the powder down low and on any terrain facing at all south. Relentless west southwest winds drifted lots of fresh snow into lee slope starting zones and formed some good sized cornices along the ridge tops.

recent activity Manageable cornice falls, wind slabs, and loose sluffs were observed this weekend, with no significant avalanche activity or deep slab avalanches reported. It's now been over a week since the extensive and widespread natural deep slab avalanche cycle, which included activity on slopes at all elevations facing most directions. Colder temperatures appear to have locked up the deep instabilities temporarily, but it's slowly warming up again up high and they may well again become active.

description
Triggered wind slab avalanches and cornice falls are likely in some exposed upper elevation terrain. Avoid freshly formed cornices along exposed ridge-lines, which are likely to break further back than you expect and stiffer drifted snow on the lee sides of major ridge lines and in and around terrain features like rock outcroppings, sub-ridges and gullies.

description
Dangerous triggered deep slab avalanches failing on preexisting faceted weak layers at the bottom of the snowpack remain possible today, especially on drifted upper and mid elevation slopes that didn't naturally avalanche in the recent prolonged cycle. The deep slab instability associated with the weak faceted snow in the basal layers appears dormant currently, but warming and a bit of new load from the weekend's accumulation and wind could reawaken it on some slopes. Be especially cautious in shallow, rocky terrain. Recently drifted and sun-warmed slopes with shallow overall snow cover are the most suspect, since shallow areas tend to harbor the weakest snow. You might trigger a deep slab from a shallower area of the slab.

Wet sluffs entraining significant piles of fresh snow will become increasingly likely as the day heats up, with solar warming and green-housing due to partial cloud cover the wildcard. Avoid steep slopes with saturated fresh surface snow and be especially careful above trees or other terrain traps that you could be dragged into. |

weather It'll be mostly cloudy today with a chance of some snow showers, west southwest winds and a high temperature at 8500' of around 36 degrees. It'll be mostly cloudy again tonight with a chance of some snow and low temperatures around 27 degrees. Similar, moist and mild weather will continue through Thursday, when a more significant and productive zonal pattern will set up, with accumulating snow a good bet.
