Uintas Avalanche Advisory

Forecaster: Craig Gordon

AVALANCHE WARNING »

Dangerous avalanche conditions are occuring or are imminent. Backcountry travel in avalanche terrain is not recommended.
Notice:

THIS AVALANCHE WARNING IS FOR ALL THE MOUNTAINS OF NORTHERN UTAH. HEAVY SNOWFALL WITH STRONG WIND IS CAUSING NATURAL AVALANCHES TO OCCUR. MORE SNOW IS EXPECTED DURING THE DAY TODAY. THE AVALANCHE DANGER IS HIGH. THE AVALANCHE DANGER WILL MOST LIKELY STAY ELEVATED OVER THE NEXT FEW DAYS. BACKCOUNTRY TRAVEL IS NOT RECOMMENDED. IF YOU CHOOSE TO GO INTO THE BACKCOUNTRY, STAY OFF OF AND OUT FROM UNDER ALL SLOPES OF 30 DEGREES OR STEEPER AND STAY OUT OF TERRAIN TRAPS SUCH AS GULLIES.


SPECIAL ANNOUNCEMENT

Elvis has not left the stadium… due to the severity of this late winter storm, he decided to come back for an encore and will issue a couple more advisories ‘til the dust settles.


BOTTOM LINE

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

Danger Rose Tutorial

At mid and upper elevations the avalanche danger is HIGH and both natural and human triggered avalanches are likely. Avalanches triggered today will be large and dangerous. In lower elevation terrain the avalanche danger is CONSIDERABLE on any steep, wind drifted slope and human triggered avalanches are probable.


CURRENT CONDITIONS

This has been some storm for the western Uinta’s and snow totals are starting to stack up. In the past 24 hours Chalk Creek received 16”, there’s 14” at Hayden Pass, a foot at Smith-Moorehouse and Trial Lake, and 8” at Daniels. Winds are nuking, blowing 50-70 mph along the ridges. Temperatures are in the low to mid teens.


RECENT ACTIVITY

Visibility has been limited the past few days, though I suspect the place is coming unglued. Click here for recent observations.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

There’s no point in theorizing about which layer avalanches will run on today. Fact of the matter is, we’ve received over four feet of snow since April Fool’s Day and now the winds are raging. What we do know is, when the wind blows in the Uinta’s, we see avalanches… today should be no different. Avalanches triggered today can break into older layers of snow, producing large and dangerous slides. Even if you’re playing on low angle terrain think about steep slopes above and adjacent to where you’re riding.


MOUNTAIN WEATHER

A cold, moist northwest flow will continue through tonight in wake of yesterday’s cold front. This is usually a good setup for the North Slope and we can expect an additional 4”-6” of snow throughout the day, before the action starts to wind down. West and northwest winds are going to be an issue, blowing in the 30’s and 40’s with gusts in the 60’s and 70’s along the high ridges. High temperatures reach into the upper 20’s and under clearing skies overnight lows crash to near zero. Clear and cold for Wednesday, then rapid warming occurs Thursday as strong high pressure builds.

Also, we've installed two beacon checkers exclusively for snowmobiler's- one at the Noblett's Trailhead, the other at the Bear River Trailhead. Thanks to Backcountry Access, the Bear River Lodge for donating one of the units and the great folks at the National Weather Service for their partnership, support and hard work making this project happen.
