Forecast for the Provo Area Mountains

Thank you for a great season!
Regular avalanche forecasts have ended. We will be issuing intermittent updates through May 1st. This most recent update is from Friday April 26, 2024.

During the spring, there are typically three different avalanche problems:
1. Wet Snow: Wet loose avalanches, wet slab avalanches, and glide avalanches
2. New Snow: New storm snow instability as soft slab avalanches and loose dry avalanches
3. Wind Drifted Snow: Wind slabs; soft or hard drifts of wind-blown snow

Weather and Snow
Yesterday's storm was a bust in terms of snowfall, with Northern Utah only picking up a trace to maybe 2" of snow across the range (0.06-0.26" water).
This morning, it's trying to snow, and mountain temperatures are below freezing at about 8,500'. The wind is from the southwest and hardly blows across the upper elevations, with speeds in the 5-15 mph range. One station famous for its south wind blows 15-20 mph.
Today, as another storm crosses into northern Utah, we should see snow showers develop this morning and last throughout the day. The rain/snow line will be around 8,000' and will likely ebb and flow. It's spring, and you cannot rule out a convective period where you might see heavier snowfall.
The wind will remain from the southwest today, and speeds should remain light. Unfortunately, this storm does not look good to me on a 500 mb map (but I am not the best at forecasting weather). It digs a little too far south and eventually becomes a closed low, and we will likely see moisture on a wrap-around northeast flow later today into tomorrow before it's gone. Snow totals are forecast to be 7-14 inches of new snow (1.30-1.90" water) by Sunday afternoon. My bet is half that.

Our partners at the National Weather Service put out a weather discussion HERE, and the mountain weather forecast will continue to be updated twice daily until May 5, 2024.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
When cold, dry snow becomes wet for the first time, you may see wet sluffs (loose snow that fans outward as it descends).
Larger wet slab avalanches can happen when melt water percolates through a layered, winter snowpack for the first time especially after multiple days of strong melting combined with no refreeze at night.
Wet avalanches usually don't last forever because over time, days or weeks of percolating meltwater, all the layers in the snow disappear, and the snow becomes homogeneous and dense, turning into a stable summer-like snowpack. Typically, this cycle of instability maturing into stability occurs first on the south-facing slopes in early spring, then progresses to the east and west-facing slopes in mid-spring, and finally, by late spring, the upper elevation north facing slopes go through a wet avalanche cycle.
Glide avalanches occur regularly in spring as the entire snowpack slides slowly on the ground like a glacier until they suddenly release into a full-depth avalanche. These occur periodically on steep rock slabs and occasionally on steep grassy slopes. Notorious glide avalanche locations include Stairs Gulch or the rock slabs in Broads Fork, which you should always avoid in spring. Avoid crossing under any slopes with telltale glide cracks in the snowpack. Remember, they come down randomly, even at night.
The bottom line for wet avalanches:
Get out early and get home early. Get off of--and out from underneath--any slope approaching 35 degrees or steeper when the snow becomes wet enough not to support your weight. Warning signs may include:
  • Rollerballs (pinwheels) in new snow that is getting wet for the first time
  • Natural or human triggered wet sluffs
  • Small sluffs fanning out into larger slides or running long distances
  • Cornices breaking off
  • Several days of strong melting combined with no refreeze at night
Avalanche Problem #2
New Snow
Type
Location
Likelihood
Size
Description
We almost always get winter-like snow storms well in the Spring. Treat each storm just like you would in winter. Avalanches can occur within the new snow typically from 1) low-density layers deposited during the storm, 2) high precipitation intensity during a storm, and 3) from wind slabs created during the storm.
It's easy to test the new snow as you travel by jumping on small test slopes to see if they avalanche or dig down with your hand to see how well the new snow is bonding. Snow can change dramatically in both space and time, so never let your guard down.
Avalanche Problem #3
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
Each storm will be worth looking at the winds to find out which direction they have blown from and what direction they will be blowing for the day. Wind can rapidly load snow onto steep slopes, making those slopes more prone to avalanching. Wind drifted snow looks rounded and pillowy; in some cases, it can sound hollow like a drum. If you see shooting cracks, it's a sign you may have hit a wind slab.

Additional Information
  • Regular avalanche forecasts with avalanche danger ratings have ended. We will continue to post all observations so please keep submitting them.
  • Learn what to watch for during spring avalanche conditions when the snow becomes wet with this video from the UAC.
  • Thanks to all of you who have sent observations this season. Crowd-sourcing is the most valuable information we get. And special thanks to all the Utah avalanche professionals: ski areas, Utah Department of Transportation, guides and educators, Powderbirds, and Park City Powder Cats.
  • Thanks to Darren Van Cleave and the National Weather Service who provide office space, weather forecasting, tech support, and great company.
  • A special thanks to all of you who donate directly to the Utah Avalanche Center. We couldn't do this without your support
  • Some ski areas are closed and each has a different uphill travel policy. Remember that areas open to uphill travel are no longer doing any avalanche mitigation work and must be treated as backcountry terrain
  • The Utah Avalanche Center is a partnership between the Forest Service and the non-profit Utah Avalanche Center. On the Forest Service side, thanks to unwavering support from our boss Renee Flanagan, Forest Supervisor Dave Whittekiend, the rest of the Uinta-Wasatch-Cache National Forest, Michael Engelhard and Brian Murdock of the Manti-La Sal National Forest and the financial support from Chris Hartman of the Forest Service Intermountain Region. Three-fourths of the Utah Avalanche Center funding along with the awareness and education programs comes from the non-profit Utah Avalanche Center. Our forecast staff includes Director Mark Staples, Drew Hardesty, Toby Weed, Craig Gordon, Brett Kobernik, Eric Trenbeath, Trent Meisenheimer, Nikki Champion, and Dave Kelly. Chad Brackelsberg leads our non-profit. Staff on the nonprofit this year include Kate Waller, Paige Pagnucco, Andy Nassetta, McKinley Talty, Jeremy Collett, Joey Manship, Paul Diegel, Liam McDonald, Claire Hurty, Robbie Allison, Greg Gagne (forecaster) and Dave Garcia (forecaster). Board of Directors are Nicole Sumner, Kate Bowman, Michael Brill, Michael Shea, Rich Mrazik, Al Richards, Caitlin Hansen, Christian Schauf, Eric Quilter, Sarah Moles, Ted Roxbury, and TJ Kolanko
  • Direct funding comes from longtime partners, Utah Division Recreation, Utah Division of Emergency Management, Utah Department of Transportation, and Salt Lake County
  • Generous support in the form of donated lift tickets and daily observations comes from Ski Utah, Alta, Brighton, Beaver Mountain, Deer Valley, Powder Mountain, Snowbasin, Snowbird, Solitude, and Vail Resorts
  • We couldn't access many areas without support and snowmobiles from Ski-Doo, Karl Malone Powersports SLC, Polaris, Young Powersports, and Northstars Ultimate Outdoors
