Lo esencial

The avalanche danger is CONSIDERABLE at all mid and upper elevations and at lower elevations northwest-north-east where avalanches may step down into older facets, leading to large and destructive avalanches. At lower elevation west-south-southeast aspects where the persistent weak layer is less likely to cause avalanches the avalanche danger is MODERATE.

Today, natural avalanches are possible and human triggered avalanches are likely.

This is a day when the avalanche danger is not as obvious as it was even a few days ago. Assess slopes carefully as we have just had a lot of new snow and things are settling out. With overcast skies and bit of fluff overnight there is still good riding to be had on slopes less than 30 degrees and that's where I will be headed today.

This last storm was a significant loading event for our November faceted layer. Reports are trickling in of avalanches that ran on the persistent weak layer (PWL). With all the new snow blanketing the old snow surface I think we're well on our way to healing this PWL. I don't think it is healed yet and that is why the danger remains at CONSIDERABLE for today. Any avalanche that fails into the November facets would be a bone breaking, day ruining, season ending avalanche.

What stands out to me today is that there is a possibility of seeing natural avalanches and human triggered avalanches are likely. Nearly half of all avalanche accidents happen during times of considerable danger. Today is a day for careful snowpack evaluation and cautious route finding. Things are getting better- enjoy the lower angle powder skiing and give this weak faceted layer some more time.

Last night's low density snow will be easily moved around with any hint of wind. You may see some wind drifted snow and small wind drifted snow avalanches. Look for cracking, collapsing, and rounded pillows of new snow. These shouldn't pose a hazard by themselves- the concern is if they step down into the buried persistent weak layer.

You may trigger a loose dry avalanche in steep terrain. Observers reported stabilizing within the new snow yesterday. This will only continue to improve. A sure fire way to avoid any deeper new snow avalanche is to choose terrain under 30 degrees.

Recent Activity

Backcountry travelers continued to report avalanches that ran during the storm.

This avalanche observationin the Rodeo Ridge area of Ben Lomond Peak from the storm cycle is an indicator of new snow instabilities that have started to settle out.

Yesterday there were reports of explosive triggered avalanches from ski area operations. Some of these avalanches were 4-8' deep, 400' wide, and ran 2500' of vertical.

Check out our observations page for the most recent information.

Snow and Weather

Under overcast skies most locations are reporting 1-2" of low density snow. Trailhead temperatures are in the mid teen's F while temperatures at 9,000' ridgelines are in the low teens F. Winds are blowing from the southwest 10 gusting to 25 MPH at the 9000' ridgelines.

Today, continued light snowfall with 1-2" of snow expected. Temperatures will be 18-22 F. Winds at the 9000' ridgelines will blow from the west 20 gusting to 35 MPH. Winds are forecasted to increase later this afternoon.

Snow Depths throughout the Wasatch
