Uintas Avalanche Advisory

Forecaster: Craig Gordon

SPECIAL ANNOUNCEMENT

Today, Sunday April 12th will be our last scheduled advisory for the season. I'll post some general snowpack and avalanche information tips tomorrow.

Thank you… thank you… thank you. Thanks to everyone who was involved with or helped support this program. In particular- huge thanks to Ted Scroggin from the Evanston Ranger District for all his timely and accurate snow and avalanche observations and for helping to educate countless riders and skiers alike. He is an enormous asset to the community and I couldn’t pull this off without his help. Also, thanks to my good colleagues at the Avalanche Center, in particular to Grant Helgeson for all his hard work with both our Avy Essentials class and the Uinta County S&R field day.

In addition, big thanks to Utah State Parks for being such an awesome partner, helping to fund this and other snowmobile specific avalanche advisory programs, ultimately saving many lives. The support from our good friends at Tri-City Performance and Weller’s Recreation in partnership with Polaris and Ski-Doo is simply amazing. Their sleds enable us to get into more terrain, see more snow and ultimately issue more precise forecasts. Also, thanks to everyone from the Park City Powder Cats. The strong working partnership and information sharing conduit forged this year should be a model for all organizations in this business… thanks guys and gals!

Finally, thanks to all of you who consistently help this program. Whether attending fundraisers, lending a hand installing beacon training sites or sharing your avalanche insights and experience… I appreciate all the support!


BOTTOM LINE

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

Danger Rose Tutorial

At and above treeline on steep, wind loaded slopes, especially those with an easterly component there's a few wind slabs that will remain sensitive to the weight of a person today. In this type of terrain a MODERATE avalanche danger exists and human triggered avalanches are possible.

In addition, the danger of wet avalanches will rise from LOW this morning morning to MODERATE on steep, sunny slopes and human triggered wet slides and sluffs will be possible during the heat of the day.


CURRENT CONDITIONS

April showers bring…. spring powder! Skies are clearing in the wake of yesterday’s storm system which deposited 2”-3” of new snow across the higher elevations. Northwest winds became a bit active overnight, blowing 30-50 mph along the high peaks, but began calming down around 4:00 this morning and are currently blowing 15-30 mph. Temperatures cooled into the low 20’s at 10,000’ and mid 20’s at 8,000’. The April storm cycle salvaged our season and the coverage is amazing. Today, you can expect dense spongy snow on sheltered upper elevation north facing slopes. Mid and low elevation south facing slopes will soften, providing a smooth, corn-like texture with a little sun and warming.


RECENT ACTIVITY

No new significant avalanche activity to report.

THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Winds have been all over the map with this last storm system- out of the south and southwest on Friday, before turning west and northwest yesterday and overnight. As you might expect, fresh drifts about a foot deep formed along the leeward side of ridges at the upper elevations. While easy to detect by their rounded or pillow-like appearance and mostly manageable, in sustained steep terrain they may pack more of a punch than you’d expect. Remember- even a small avalanche can slam you into a group of trees or carry you over a cliff band and that’ll ruin your day in a hurry. Today you’ll want to gather some information by stomping on small test slopes and road cuts and see how they react before committing to big terrain.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

For better or worse, nearly everyone who’s spent time in the mountains during the winter months has a cornice story. Talking with other folks around the range, we’re amazed at how big cornices have grown, especially during the last storm cycle. As a matter of fact, they’re epically huge and may break back much further than you’d think. I’d continue to give these unpredictable pieces of snow the respect they deserve and avoid messing around with them.


THREAT #3

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

With strong sunshine overhead and temperatures rising into the low 40’s, wet avalanches will be an issue on steep sunny slopes, especially at mid and lower elevations. Like clockwork, once you find the snow getting damp, manky and unsupportable either head to a cooler, shadier aspect or call it a day. In addition, avoid terrain traps like gullies where even a shallow, seemingly benign avalanche can pile debris very deeply.


MOUNTAIN WEATHER

We might still see a lingering snow flurry or two, but in general high pressure is building and it’ll be a beautiful day in the mountains. Northwest winds will blow in the 30’s and 40’s along the ridges and begin to decrease later in the day. Highs at 8,000’ will be in the low 40’s and at 10,000’ in the mid 30’s. Overnight lows dip into the low 20’s. Sunny skies and slightly warmer temperatures are on tap for Monday and early Tuesday, then winter returns late Tuesday and lingers into Thursday. Looks like a good shot of snow in a cold, northwest flow.


GENERAL ANNOUNCEMENTS

Remember- your observations help to save other riders lives. So if you see or trigger any avalanches please let me know what your seeing. You can reach me at 801-231-2170 or craig@utahavalanchecenter.org

Also, Beacon Basin is up and running and located inside the orange fencing on the northeast corner of the Nobletts Trailhead.
