avalanche watch THIS AVALANCHE WATCH IS FOR THE MOUNTAINS OF NORTHERN AND CENTRAL UTAH INCLUDING THE BEAR RIVER (LOGAN)...WASATCH...AND MANTI SKYLINE RANGES. A SERIES OF STORMS WITH STRONG WINDS HAS INCREASED THE AVALANCHE DANGER TO HIGH ON SOME SLOPES. THE AVALANCHE DANGER WILL CONTINUE TO INCREASE THROUGH THE WEEKEND. BACKCOUNTRY TRAVELERS SHOULD AVOID TRAVEL ON AND BELOW STEEP SLOPES. THIS WATCH DOES NOT INCLUDE SKI AREAS OR HIGHWAYS WHERE AVALANCHE CONTROL IS NORMALLY DONE. |

current conditions The Tony Grove Snotel at 8400' reports over a foot of new snow in the last 24 hours, containing 1.3 inches of water. It's 16 degrees this morning, and there is 48 inches of total snow containing 75% of average water content for the date. I am reading increasing west winds again this morning at both the UDOT Hwy 89 Logan Summit and the Mt. Ogden wind sensors, with 40 mph average southwest winds and gusts to 50 on Mt. Ogden and 25 mph average wind speeds at the UDOT sheds in upper Logan Canyon. Similar readings during yesterday's blizzard. The 9700' Logan Peak weather station reports 12 degrees, and southwest winds, but I'm not trusting the unusually light windspeed readings.. I found the rapidly accumulating snow yesterday slightly inverted or a bit heaver on top, and obvious significant drifting was ongoing when I headed down canyon in the mid afternoon. Observers also reported difficult trail breaking in the deep powder and underlying weak sugary snow and red flags including rapid accumulation, extensive drifting, and cracking. Poor visibility, heavy snowfall, and extensive drifting in Garden City Bowls on 1-9-2014. (McAvoy)

recent activity Ski areas in the Wasatch Range report active avalanche control yesterday, with easily triggered wind slabs. Locally, i was able to trigger small soft slabs on small test slopes in the backcountry near Beaver Mt. yesterday afternoon. I noticed some natural activity involving the new snow in Logan Canyon below Temple Fork. Waiting for observed evidence of natural activity today.....

description
Dangerous wind slab avalanche conditions exist in exposed upper elevation terrain, and the danger will increase and become more widespread during the day as more snow accumulates and is drifted by increasingly strong west winds. Triggered wind slab avalanches are likely on steep slopes with recent deposits of drifted snow. Wind slabs generally form on the lee side of exposed ridge lines, but can also form on any slope aspect, especially in and around terrain features like gullies, scoops, sub-ridges, rock outcroppings, and cliff bands. Avoid steep slopes with recent wind deposits, which are often smooth, rounded and chalky looking, and can sound hollow or drum-like. It is possible that a smaller wind slab avalanche could step down into weak old snow, producing a larger more dangerous avalanche. Triggered and natural sluffs and soft slabs involving the fresh storm snow are likely in steep terrain, and you should avoid traveling below steep slopes, especially during periods of particularly heavy snowfall or gusty winds when natural avalanches will be the most likely.

description
We still don't know if enough loading occurred yesterday to reactivate widespread persistent weak layers, but with all the obvious drifting going on I suspect at least some avalanches will step down into old snow today. Dangerous human triggered avalanches failing in old weak faceted snow or in the basal layers of the existing snow pack are likely on slopes with poor snow structure, especially in drifted upper elevation terrain. New snow from yesterday or accumulating in the next couple days is likely to reactivate the buried weak layers, and persistent slab avalanches will once again top the danger priority list. I've recently found very weak faceted snow on slopes facing every direction and at all elevations, so we'll find a danger of persistent slab avalanches pretty much anywhere a significant slab layer develops. Audible collapsing or whoompfing is a significant red flag indicating serious persistent slab avalanche potential. Drifting, rapid accumulations, other avalanches and cracking are other red flags to take heed of today. As more new snow piles up creating a cohesive slab layer, it is becoming more likely that you could trigger avalanches remotely, from a distance, or worse, from below.

weather We'll see more stormy weather in the mountains today, sustained and strong westerly winds, and periods of heavy snowfall, with 3 to 5 inches of additional accumulation forecast by this evening. Expect 8500' high temperatures around 25 degrees. Snowfall will continue tonight and decrease tomorrow, with westerly winds remaining in the strong category. Stormy weather should continue through much of the weekend, with another strong frontal passage, with heavy snowfall, and strong winds expected Saturday night and into Sunday.
