Forecast for the Provo Area Mountains

Nikki Champion
Issued by Nikki Champion on
Wednesday morning, February 12, 2025
A MODERATE avalanche danger exists on mid and upper-elevation northwest to east-facing slopes, where avalanches up to 1–3 feet deep and several hundred feet wide may be triggered on weak layers. While natural avalanches are unlikely, human-triggered avalanches are possible.
The danger is highest along the Wasatch Back near Ant Knolls and upper Snake Creek, which may mirror the SLC area hazard.
MODERATE danger also applies to other steep slopes with wind-drifted and lingering new snow, where unstable slabs may exist. Approach avalanche terrain with caution—conditions are complex and variable, so be ready to adjust plans.

Special Announcements
It’s been a tough few weeks for the backcountry community, with too many close calls and heartbreaking losses. Our thoughts are with everyone affected—this is a tight-knit group, and these tragedies hit hard.
As more details come in, accident reports will continue to be updated and published. If you have a moment, consider reading through one or more of them.
  • A preliminary report on Saturday’s avalanche fatality in the East Bowl of Silver Fork can be found [HERE].
  • The full report on the February 3rd avalanche fatality on Monte Cristo (Ogden Mountains) is published [HERE].
  • The accident report detailing the full and partial burial close call in Dutch Draw (Park City ridgeline) from Saturday is available [HERE].
Weather and Snow
This morning, temperatures are between -0°F and -6, not factoring in wind chill. Winds out of the west-northwest have been steady overnight, averaging 10–15 mph with gusts up to 25 mph at mid-elevations and 30–40 mph gusting to 50 mph at the highest ridgelines. Lake-enhanced snowfall continued overnight, with up to 1 inch of light, low-density snow.
Today, temperatures will rise to 13–15°F. Light snow showers may linger this afternoon before tapering off as drier air moves in. Winds will remain westerly to west-northwest through Wednesday, shifting to southwest early Thursday morning. Wind speeds will average 5–10 mph with gusts up to 20 mph at mid-elevations and 20–30 mph with gusts of 30–40 mph at the highest ridgelines.
The forecast calls for a long-duration storm with significant snowfall, bringing 18–28 inches between February 13th and 16th. Snow will begin in the Wasatch by Thursday afternoon and continue through Saturday, with the heaviest snowfall expected late Thursday into Friday morning as a system adds instability.
I’m keeping a quote from Drew’s forecast yesterday because it sums up what many of us are feeling:
"It's some of the best skiing and riding of the year right now, but we don't sit easy in the forecast office. I view the snowpack structure as fairly complex with a lot of avalanches failing on a lot of different weak layers. Some of the weak layers formed in November and December, some in late January, some with Friday's blockbuster storm. When the snowpack gets complex, I recommend choosing the simple option: low-angle terrain. There's plenty of slopes 30° or less that offer excellent riding without having to thread the needle or outsmart the avalanches. Just my 2 cents from 25 years in the easy chair."
Recent Avalanches
No new avalanches were reported in the backcountry on Tuesday, but over the weekend the Provo area mountains saw recent avalanche activity.
  • On Saturday, a snowmobiler unintentionally triggered a large avalanche near Ant Knolls, 3 feet deep and 250 feet wide, on a steep northeast-facing slope at 9300'.
  • Another snowmobile-triggered avalanche was reported in the upper Snake Creek area, 1-3 feet deep and hundreds of feet wide on northeast-facing slopes. See the photo below.
As winds and a bit of snowfall ramped up yesterday afternoon, ski resorts reported sensitive wind slabs forming at upper and mid-elevations.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description
Two buried weak layers of faceted snow in the snowpack continue to be triggered by skiers and riders—this is not speculation. The evidence is clear, check the avalanches tab for the recent examples from Monday and this past weekend.
  • The upper weak layer is buried around 1–2 feet deep, formed during the cold weather at the end of January.
  • The lower layer, near the ground, formed in November/December and has caused many large avalanches. This layer is most likely to be triggered in steep, thin snowpack areas, and repeater slopes—places that have previously avalanched. This layer continues to avalanche, continues to reload, and continues to be an issue.
Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
With the overnight increase in winds and soft snow available for transport, you may trigger shallow hard or soft slabs of wind-drifted snow today, especially on steep north, east, and south-facing slopes. Watch for pillow-shaped deposits and avoid them. Signs of instability—shooting cracks, collapsing, and overhanging cornices—indicate unstable terrain.
Outside the wind zone, especially on shaded slopes, new snow could still be sensitive in steep terrain. These interfaces are slowly stabilizing, but soft slabs are still possible on many aspects and elevations.
