Forecast for the Provo Area Mountains

Issued by Trent Meisenheimer for
Saturday, April 15, 2023
The avalanche danger is LOW as we generally have safe avalanche conditions. Watch for unstable snow on isolated terrain features. Both natural and human-triggered avalanches are unlikely.

Slide-for-life conditions (where you are unable to arrest after falling) are possible on smooth, hard, and frozen snow surfaces.

Special Announcements
The final UAC report for the Upper Weber Canyon avalanche accident on March 9 has been published and is available HERE. The UAC would like to thank Park City Powder Cats for sharing information about the timeline of the accident and allowing UAC staff access to the avalanche after the incident.
Weather and Snow
Under mostly clear skies, the mountain temperatures have now been below freezing for the past 48 hours. Current mountain temperatures range from 17-23 °F. Winds are blowing from the west-northwest at speeds of 5-10 mph, gusting into the 20s across most upper-elevation ridges. The free air (11,000') moves much faster and blows west-northwest at 35-40 mph.
We will have plenty of sunshine today, with temperatures rising into the mid-40s °F at roughly 7,000' in elevation. Winds will remain from the west-northwest and blow 5-15 mph. The best riding conditions will be on lower-angled sun-lit slopes that do not have roller balls or wet avalanche debris. If your slope angle is too steep, you won't have the smooth (see photo). Other slopes are frozen solid and will be teeth-chattering.

Recent Avalanches
No new avalanches were reported from Friday. However, avalanches from the past week continue to come through the door. A number of excellent observations came in from Dave Jarvis talking about the recent wet avalanche cycle in the Provo area and can be found HERE.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
Today we will welcome the sunshine to hopefully soften and improve the riding and turning conditions, as the snow surfaces are bulletproof this morning. However, remember that the Provo Range has many aspects and elevations and if you find yourself on any slope where the sun has warmed the surface too much, and you're sinking into unconsolidated wet snow, it's time to leave or change aspects.
Avalanche Problem #2
Cornice
Type
Location
Likelihood
Size
Description
Massive cornices are draped and drooped on almost all mid and upper-elevation ridgelines and these cornices demand respect. When traveling on ridgelines give those cornices a very wide berth, as they will break back much further than you think. Also, avoid being underneath these cornices as they can break at any moment sending massive chunks of ice and snow your way.
Avalanche Problem #3
Gliding Snow
Type
Location
Likelihood
Size
Description
Glide avalanches are extremely dangerous and destructive as the entire season's snowpack avalanches to the ground. One full-depth glide avalanche on the Raymond Slabs in Porter Fork of Mill Creek released on Tuesday. Another glide avalanche was reported yesterday in Broads Fork that likely happened on Wednesday, April 12th. Merritt and Dan shared the photo below from Provo Peak showing a glide crack opening up.
Avoid traveling in areas known for glide avalanches, such as Provo Peak (photo below) Stairs Gulch, Broads Fork, Mill B South, Mineral Fork, Porter Fork, and others.
