Forecast for the Provo Area Mountains

Drew Hardesty
Issued by Drew Hardesty on
Wednesday morning, March 26, 2025
The mountains will continue to fall apart today.
The avalanche danger will quickly rise to CONSIDERABLE on easterly to southerly to westerly facing slopes for destructive wet loose and wet slab avalanches. The danger for wet avalanches will also elevate to MODERATE on some northerly facing slopes at the mid and some upper elevations. CORNICES are a significant hazard. They may release naturally and trigger large avalanches below.
Travel Advice: It's a day to avoid steep, avalanche prone terrain, particularly by mid/late morning.

Weather and Snow
Skies are clear.
With a storm developing off to the west, winds have picked up overnight from the south and are blowing 10-15 with gusts to 20.
Mountain temperatures are wicked hot with overnight "lows" in the low to mid-40s. Highs reached into the upper 40s to mid-50s yesterday.

Today look for sunny skies and increasing high cirrus by late afternoon. Winds will remain generally light (less than 15mph) from the southwest. Mountain temps will be a touch warmer than yesterday. Your window for safe travel on supportable crusts will be earlier and more narrow than it has over the last couple of days.
Thursday will be just a touch cooler but with more cloud cover and moderate winds from the southwest. Blessed relief, if not salvation, arrives Saturday with much cooler temps, if not a momentary return to winter. In truth, the models hint at a somewhat active weather pattern for the week.
Recent Avalanches
The wet snow shed cycle has begun. Yesterday went off with widespread natural wet avalanching on many steep solar aspects and even some low and mid-elevation northerly facing couloirs. These were primarily wet loose avalanches leaving debris piles easily large enough to bury a person. Cornices, too, were tender and a large cornice fall along the Cascade ridgeline triggered a large hard slab avalanche below that ran over 2000' down the slope in upper Bunnels Fork of the South Fork. This avalanche was on a steep east facing slope at nearly 11,000' was 3.5' deep and 200' wide failing on weak sugary facets near the ground. This path avalanched earlier this winter.

Description
Natural and human triggered wet loose and some wet slab avalanches can be expected today and your window for safe travel on supportable crusts will be earlier and more narrow than the last couple of days.
A couple things of note:
  1. Wet loose avalanches on nearly all aspects and elevations. Mountain temperatures will be warmer than yesterday, with daytime highs at 10,000' likely reaching into the mid-40s. Some upper elevation (above 9500') north facing slopes may be susceptible to wet loose avalanches.
  2. Wet slab avalanches. Some areas have not had a proper deep freeze for a couple of nights and free water pooling at various structural interfaces tends to promote wet slab releases. These wet slabs may be more likely on easterly or westerly facing aspects at the low and especially mid-elevations and be 1-4' deep and perhaps 1-200'+ wide. Wet slabs are generally much more dangerous and destructive than wet loose.
  3. Cornices are becoming weak and tender and are big enough to trigger large avalanches below, particularly on slopes that have avalanched previously this season. These are generally mid and upper elevation northwest to east facing slopes.
  4. Roofs are shedding their winter loads. Please keep an eye on people, kids, animals underneath the roof lines.
