Forecast for the Ogden Area Mountains

Issued by Greg Gagne for
Friday, April 14, 2023
The avalanche danger is Low.
The two avalanche problems to watch for are (1) cornices along exposed ridgelines at the mid and upper elevations, and (2) glide avalanches in terrain with glide cracks. You also may find low elevation snowpacks haven't yet had a deeper freeze and there may still be wet, unconsolidated snow underneath a shallow refreeze.

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

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
This Morning: After nearly four days of above-freezing temperatures, yesterday's cold front brought much-needed colder air and temperatures now range through the teens F. Winds are northerly and light. Skies are partly-cloudy. The temperature graph below from the Strawberry lift at Snowbasin at 9,200' shows the drop in temperatures with the arrival of colder air.
Today: Partly-cloudy skies with a chance for light snow showers this afternoon. Temperatures will be in the 20's F and the north/northwest winds will be light, gusting into the teens.
This Weekend: Stronger winds overnight and into Saturday with mostly sunny skies and a warming trend that may provide decent corn conditions by late this weekend. A chance for light snow by midweek.
Recent Avalanches
No reports of avalanches on Thursday.

Avalanche Problem #1
Cornice
Type
Location
Likelihood
Size
Description
Huge cornices will be found along most exposed ridgelines at the mid and upper elevations. Although today's cold temperatures may make these cornices less sensitive, it is still possible to have a cornice collapse beneath you when traveling along a corniced ridgeline, and natural cornice falls are also possible. Any cornice that breaks will consist of Subaru-sized frozen chunks of snow that you do not want to be involved with.
Drew Hardesty has written about avalanche fatalities in the modern era in Utah and reports there have been six avalanche fatalities in Utah since 1940 due to cornice falls.
Avalanche Problem #2
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 Tuesday in the Salt Lake. mountains. Watch for visible glide cracks (as shown in the photo below) as an indication of terrain where glide avalanches are possible. The most likely areas for glide avalanches are Chilly Peak and the north side of Willard Peak.
Today's colder temperatures do not help minimize glide avalanches as liquid water has already greased the smooth, rocky bed surfaces.
We have had two accidents (including a fatality) with glide avalanches in the past 22 years:
