Thank you for a great season!
Regular avalanche forecasts have ended. This most recent update is from 7AM on Thursday, May 1, 2025. This is our last intermittent update for the season.
You can submit observations and avalanches HERE, and check out the most recent observations and avalanches HERE.

During the spring, there are typically three different avalanche problems:
  • Wet Snow: Wet loose avalanches, wet slab avalanches, roof slides, and glide avalanches
  • New Snow: New storm snow instabilities; soft slab avalanches and loose dry avalanches
  • Wind Drifted Snow: Wind slabs; soft or hard drifts of wind-blown snow

Special Announcements
If you are looking to travel uphill at the ski areas then check out the UAC Uphill Travel Policy page before heading out.

Researchers Sara Boilen and Ian McCammon are developing an open-source tool to help individuals mitigate risk in avalanche terrain. The project's first stage involves interviewing backcountry recreationalists who have been traveling in avalanche terrain for at least one season. All participants will be entered to win prizes. Please encourage taking 1-2 minutes to fill out their initial survey. Link HERE
Did you know the UAC has a podcast?
Check out the most recent episode detailing the history of the non-profit Friends group HERE. We sat down at the studio in late March with past executive directors Wendy Ziegler, Colleen Nipkow, Paul Diegel, Chad Brackelsberg, and current ED Caroline Miller. Fun walk through UAC history.
Weather and Snow
It was all smoke and mirrors, and when they pulled back the curtain, nothing was there. Actually 1-2" was there along the highest elevations in Ogden to SL to Provo. So it goes this spring. The longer range models have a closed Low pressure system wobbling through late weekend into early next week. These are notoriously challenging to forecast, but looks like it should provide some more precipitation.
Alta wrapped up April with 538" for the season, Brighton reported 470", and Park City Mountain Resort (south end) reported 293". Snowbasin reported 279". The Provo mountains picked up 27" SWE (snow-water-equivalent) at Aspen Grove.
There is still plenty of snow in the high country, with 80-120" in BCC to LCC, respectively, and 40-60" or more up high in PC and Mill Creek Canyon. The Ogden mountains have 40-50" up high while Provo has 25-40" up high.
Thanks again for another great season. Look for our Annual Report in the coming weeks.

Our partners at the National Weather Service put out a weather discussion HERE and the mountain weather forecast will continue to be updated twice a day through the last week of April.
Recent Avalanches
We will continue to post avalanches and observations. You can submit what you're seeing HERE, and check out all recent avalanches and observations HERE.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
When cold, dry snow becomes wet for the first time, it almost always means 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 warm temperatures combined with no refreeze at night.
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. Avoid crossing under any slopes with cracks to the ground in the snowpack. Remember, they come down randomly, even at night.

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
These signs mean it's time to head home or change to an aspect with cooler snow. Remember, even "smaller" slides can be dangerous in high-consequence terrain, such as above a terrain trap, trees, rocks, cliffs, or a long, large avalanche path.
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. Avoid any steep slope with recent wind deposits.
Practice good backcountry protocol:
  • Check your gear before every tour, and make sure each person has a working transceiver, shovel, and probe before entering avalanche terrain
  • Only expose one person to a steep slope at a time
  • Never travel above other people
Avalanche Problem #3
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
Wind can rapidly load snow onto steep slopes, making those slopes more prone to avalanching. Avoid slopes greater than 30° in steepness if you see signs of wind-drifted snow, such as rounded and pillowy features, and shooting cracks. In some cases, wind-drifts can sound hollow like a drum.
