Salt Lake Avalanche Advisory

Forecaster: Bruce Tremper


Bambara Snowstorm Special

Celebrating the onset of winter, first snowfalls and the opening of Utah's ski resorts, executive chef Nathan Powers of the award-winning Bambara, a downtown Kimpton restaurant, has created "Snowstorm" specials to benefit the Utah Avalanche Center. From Monday, November 1 through Friday, November 12, a dollar from each “Snowstorm” special (only $13) will be donated to the Utah Avalanche Center. For more info, find them online.

Danger Rose Tutorial

The avalanche danger is generally LOW with pockets of MODERATE danger from localized wind slabs along the highest peaks and ridgelines. As always, avoid steep slopes with recent wind deposits. Also, watch for rocks hiding beneath the light powder snow on the surface.


We've had a few variable, mountain-level clouds overnight and ridgetop winds have picked up to 15 mph from the west and northwest with winds up to 30 on the highest peaks. Temperatures are around 12 degrees.

The northerly facing slopes in the upper elevations of the Cottonwood Canyons and Provo mountains have up to 3’ of very supportable snow on the ground, topped off with about 6 inches of very nice powder. Unfortunately, snow depths rapidly taper to about 1 foot on the sunnier slopes and as you drop in elevation below about 9,000'. Checking weather stations in the Ogden area mountains, the snowpack there seems to be in the 12 inch range. Although the snow is quite supportable with a mid-pack ice crust, remember that it's still early season and it's all too easy to bang up your gear. And every year, we usually see a couple broken bones or smashed skulls by hitting rocks.


Yesterday, there were no reports of human triggered avalanches despite many people crawling all over the upper Cottonwood Canyons.


      Over the next 24 hours.

Winds have picked up overnight on the highest peaks to 30 mph gusting to 40 from the northwest but on most ridgelines, the winds are a more reasonable 10-15 mph. With about 6 inches of very low density powder on top, it doesn't take much wind to create dangerous wind slabs. You will find these mostly at the highest elevations and high ridgelines in downwind terrain. Luckily, you can easily spot wind slabs with their smooth, rounded shape, their hollow sound and their slabby feel. Today, as always, you should avoid any steep slope with recent wind deposits. Otherwise, the snowpack is mostly very stable.


We should have scattered, mountain-level clouds increasing to mostly cloudy by afternoon. Ridgetop winds will blow 15 mph from the northwest with speeds up to 30 mph on the highest peaks. Ridgetop temperatures will rise today from 12 degrees this morning to near 20 this afternoon, with temperatures rising to the mid 20's down at 8,000'.

The extended forecast calls for a brush-by storm passing to the east of us tonight and again on Sunday bringing a chance for light snow showers without much accumulation.
