Avalanche Advisory
Advisory: Salt Lake Area Mountains Issued by Bruce Tremper for Wednesday - April 23, 2014 - 7:04am
special avalanche bulletin

We have gone to intermittent avalanche advisory updates for the rest of April.  The next advisory will most likely be Friday, April 25th.  We are not publishing danger ratings or individual avalanche problems but just giving general avalanche information.

We are still publishing observations so keep them coming if you are getting out in the backcountry!!

current conditions

Four inches of new snow fell at Alta overnight on a well-settled, wet, dusty, spring snowpack. Temperatures have plummeted with the passage of the cold front and they are in the mid teens this morning. Luckily, the wind dropped before much of the new snow fell. So in theory, the new snow should be bonded fairly well to the old snow surface and there should not be too many problems with wind slabs within the new snow. The ski resorts that are still open report mostly stable conditions this morning but still, you should always be suspicious of recent deposits of wind drifted snow in steep terrain. The old snow surface should be well frozen this morning. Remember, you can always check current conditions for yourself at the National Weather Service Snow Page.

In the next couple days, as temperatures rise and if the strong, spring sun drenches the mountains, watch for shallow, wet sluffs within the new snow in steep terrain, especially in the heat of the afternoon.


Temperatures should pop back up in the 40's on Thursday and Friday but we're expecting partly mostly cloudy to partly cloudy skies. Ridge top wind should remain from the northwest today 10-20 mph and turn southwesterly on Thursday.

Then we have another similar-looking storm for the weekend with about 6 more inches of new snow.

Remember, you can always check weather conditions yourself at one of many great weather sites on the Internet. Here are a few of my favorite sources:

Cottonwood Canyons Forecast from the National Weather Service
The Alta meteogram from the National Weather Service
And my personal favorite, if you want to get more hard core, the NAM-12 Theda-e time-height from the University of Utah Department of Meteorology.

Contact the Ski Patrol at each resort for details. IMPORTANT: Before skinning at a resort under new snow conditions, check in with Ski Patrol.  Resorts can restrict or cut off access if incompatible with control and grooming operations.
