Avalanche Advisory
Advisory: Logan Area Mountains Issued by Toby Weed for Friday - November 21, 2014 - 6:52am
bottom line

There is a LOW or level 1 danger in the backcountry today, but a strong Pacific storm is headed in our direction. Heavy snowfall and strong winds from this will likely create dangerous avalanche conditions at upper elevations tomorrow and over the weekend. Practice now using safe backcountry travel protocols and refresh with your rescue equipment.




special announcement

We look forward to seeing you at our annual fundraiser party at the Italian Place in Logan on December 3...

We are offering a free "Know Before You Go" avalanche awareness talk tomorrow, November 22 at 2:00 at Buttar's Tractor in Tremonton.

current conditions

There's 21 inches of total snow this morning, containing 108% of average water for the date, and a temperature of 28 degrees at the 8400' Tony Grove Snotel. Southwest winds are currently averaging around 15 mph, and the CSI Logan Peak Weather station reports 23 degrees at 9700' on Logan Peak. Last weekend's snow is already showing the effects of a strong temperature gradient and resulting sublimation, and its starting to get a bit sugary. Frost or surface hoar crystals are also starting to show up in some lower and mid elevation areas. The Tony Grove road is not maintained for wheeled travel in the winter, and I'm not sure if you can get up anywhere near the lake. You can find good road and and open meadow riding up high, but remember the snow you see is all we have, there's no base!

Feathers of Surface Hoar or frost like these in Wood Camp Hollow can become a persistent weak layer if buried intact.

recent activity

No avalanches were yet reported this season in the Logan Zone, but it was active in the Wasatch last weekend.

We all need an early season rescue equipment shakedown. Replace the batteries in your beacon and check to make sure your shovel and probe are operational. Practice simple rescue scenarios in the shallow snow and force your partners to partake. Practice is required and you can and should work training into early season snow play...

weather

It'll be mostly clear and fairly mild in the mountains today, with high temperatures in the mid thirties at 8500'. Southwest winds will increase overnight and some snow is possible in advance of a strong storm, which will affect the region on Saturday. Expect increasing avalanche danger with strong and increasing southwest winds and heavy snowfall, and around a foot of accumulation possible on Saturday. Snowfall should continue Saturday night through Sunday, and intensify again Sunday night with another foot or so possible then.
