Logan Avalanche Advisory

Forecaster: Toby Weed


Hope to see you at the 6th annual "Pray for Snow" Friends of the Utah Avalanche Center fundraiser dinner on Wednesday, December 2nd at 6:30 at the Italian Place on Federal Ave. Here's your chance to support your very own local avalanche center......


Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

There are pockets with a MODERATE danger of persistent wind slab avalanches on steep drifted upper elevation slopes. Triggered slab avalanches are possible above 8500' on some slopes steeper than about 35 degrees with old and building wind slabs on weak preexisting snow.


Snow cover is limited to north facing upper elevation slopes, and hitting rocks or other shallowly buried obstacles probably still presents the largest safety concern....

Riding is still pretty much confined to upper elevation roadways, and you have to slow down and watch out for pedestrians, especially in congested areas like Tony Grove.


On Monday, I triggered a fairly large avalanche from the ridge in the West Tony Grove Area. I stamped my ski on the drifted snow along the low angled ridge line when the slab pealed out along the ridge in front and washed into the bowl below. The avalanche, triggered at 9400' on a north northeast facing slope was 1 to 2 feet deep, around 300' wide, and ran around 600' vertical. It was a a bit larger and the slope a bit more sensitive than I'd expected, and it caused us to reevaluate our plan and return to safer, lower elevation sheltered terrain.

      Over the next 24 hours.

Today, there are pockets where you might trigger persistent wind slab avalanches in the 1 to 2 foot deep category on steep drifted slopes with preexisting snow in exposed terrain.


No probability identified.
No size identified.
No trend identified.

Probably rocks will still be the biggest threat out there, but now you should certainly begin to follow proper traveling protocols and carry and practice with your avalanche rescue gear...

Remember; try to get into the habit of, when ever possible, only exposing one member of your party to avalanche risk at a time. This really means spread out farther when traveling on or under steep terrain...


Looks like the next Pacific storm system is splitting on the West Coast. Expect only weak dynamics and not much moisture.....Expect mountain temperatures to be a bit cooler today, while the Valley should warm up at little this afternoon. I'm currently reading 29 degrees and there are 30 mph southwest winds at 9700' on Logan Peak. There is a chance that we might get a little snowfall tonight and tomorrow, but it doesn't look like much at all...A high pressure system will build back in and control the weather for the first part of next week. The next storm system is expected around midweek, but the models are in disagreement apparently making a forecast difficult. Guess its time to keep the fingers crossed....


We will be issuing intermittent avalanche advisories as conditions warrant. I'll begin to issue regular advisories in December when the winter season gets rolling....
