Forecast for the Ogden Area Mountains

Drew Hardesty
Issued by Drew Hardesty on
Friday morning, December 12, 2025

A pockety MODERATE avalanche danger exists on some steep west to north to east facing slopes in the mid and upper elevations for triggering a 12-18" thick slab that fails on our old early season facets. Exercise caution in this terrain. The danger for wet avalanches will rise to MODERATE on many slopes today. Wet sluffs and possibly wet slabs will be likely in the coming days.

Weather and Snow

Skies are clear with light to moderate wind from the west-northwest. Temps are in the 30s with some overnight "lows" along the mid-elevation thermal belt near 40°F. Riding conditions and thin and threadbare at the low and mid-elevations but with up to 2 feet of snow up high. Forecasters Nikki Champion and Brooke Maushund were up along the Ogden Skyline yesterday and described that 2 feet up high in the following way:

A mix of snow surfaces out there. At lower elevations or on solar aspects, the snow was damp. In spots that had warmed up and then dipped back into the shade, a thin melt freeze crust formed, which made it tricky to hold an edge and sometimes supportable and sometimes not. In the wind zone, we found the spectrum. Along the ridge crests, there were big, supportable wind drifts you could arc turns on, all the way down to thin wind skins that you could punch through while turning.

But at least it was beautiful out. It'll be the same today: sunny skies, light to moderate wind from the west-northwest, and temps rising into the upper 40s. Warmer and milder conditions are expected over the weekend with some glimmers of hope for snow on the horizon. We'll see.

Recent Avalanches

There were no new avalanches reported from the backcountry or the ski areas yesterday. The last reported avalanches were from the widespread natural avalanche cycle over the weekend - the heavy, dense snow and wind easily tipped the scales with soft slabs failing 12-18" deep on the old faceted snow.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description

A persistent weak layer (PWL) of early season facets makes up the base of the snowpack on west-north-east facing slopes at the mid and upper elevations. In these areas, it is still possible to trigger an avalanche up to about 18 inches deep and over 100 feet wide. Cracking and collapsing are become less common and snow tests hint at slow stabilization, yet persistent weak layers come by their name honestly. It is true that in some areas, the snowpack has warmed and become isothermal and this may end up being a good thing...but facets are facets and it's just part of their character: they are just hard to trust. Exercise caution if you're traveling through steep terrain with this poor structure.

UAC staff were up near Powder Mountain Wednesday to look at the snowpack. Trent Meisenheimer explains what he saw in the video below. (LINK). The full report can be found HERE.

Avalanche Problem #2
Wet Snow

Description

Wet sluffs and wet slab avalanches will start to become a problem today through early next week. I've always felt uncomfortable forecasting wet avalanches and feel even less comfortable forecasting wet avalanches in mid-December. My recommendation - to keep it simple - is to pull the calendar off the wall and just observe what you're seeing and note how it feels under your feet. If you're seeing wet rollerballs and loose point releases and/or the snow starts to feel punchy and unconsolidated, head for a different aspect or low angle terrain. Remember that wet loose debris can pile up deeply in terrain traps.
