Forecast for the Uintas Area Mountains
Saturday morning, April 7, 2018
HEADS UP- FREAKY WEATHER... MAKES FREAKY AVALANCHE CONDITIONS. Rain on our snowpack will create dangerous avalanche conditions on all snow covered slopes, on all aspects, and all elevations.
As the storm materializes and rain falls at the highest elevations. the avalanche danger will rapidly rise to CONSIDERABLE. Both natural and human triggered avalanches are LIKELY on all aspects and all elevations. Steep, rocky terrain facing the north half of the compass and slopes with a thin, weak snowpack are particularly vulnerable. Deep, dangerous, tree snapping avalanches are nearly certain in terrain with these kind of characteristics.
Special Announcements
This Sunday April 8th will be the last of the regularly scheduled advisories for the western Uinta Mountains.
Weather and Snow
A very moist and mild westerly flow delivered an inch or two of wet, heavy snow yesterday. This morning under a blanket of thick clouds, current temperatures are mild, hovering right around freezing and a rain/snow mix is falling. West and southwest are relatively light, blowing in the teens and 20's along the high ridges. Riding and turning conditions are gonna be a bit underwhelming... might be a good day to get some projects off your plate and regroup with a little fresh snow tomorrow.

Well this is a heck of a way to run a winter. Pictured above... a tale of two trailheads. Common theme... while still closed, they're both toast and dry for miles.
A great body of recent trip reports, observations, and snow data here.
Recent Avalanches
No significant avalanche activity to report from yesterday.

Wet Snow
Description
Let's face it, our troubled snowpack has dealt with a lot this year. From infrequent storms, to early season raincrusts with facets sandwiched in between, and now a final test of its strength and endurance.... a soaking rain is on tap.... yikes! These are uncharted waters for us and I don't know exactly how it'll play out. What I do know is this- rain on snow is no Es Bueno and I bet we see some unusual avalanche activity, especially on slopes that have had a shallow, weak snowpack all season. Deep, dangerous, tree snapping avalanches that break to the dirt and remove the entire seasons snowpack aren't out of the question and once triggered, these slides will be piling up huge amounts of bone twisting debris.
Wet Snow
Description
With mild temperatures in place along with rain and snow in the forecast, the danger for wet slides and sluffs increases throughout the day. Any avalanche triggered can easily gouge into weaker layers of snow buried deeper in the snowpack, creating a much larger avalanche then you might expect.
Additional Information
Moisture streaming inland off the Pacific maintains a warm, wet day. High temperatures climb into 40's and southwest winds blow in the 30's and 40's along the high ridges. Colder air arrives late this afternoon and snow levels lower tonight before tapering off by Sunday morning. Snow and water totals could be similar... with an inch or two from each department.

If you're getting out and about, please let me know what you're seeing especially if you see or trigger and avalanche. I can be reached at [email protected] or 801-231-2170
It's also a good time to set up one of our very popular avalanche awareness classes. Reach out to me and I'll make it happen.
