Forecast for the Ogden Area Mountains

Dave Kelly
Issued by Dave Kelly on
Monday morning, March 25, 2024
There is a MODERATE avalanche danger on all aspects at the mid and upper elevations where human triggered soft slab avalanches are possible. The avalanche danger is LOW in lower elevation terrain.
Today, avalanches will fail on a density change within the newest snow. During periods of heavy snowfall or wind transporting snow the likelihood of triggering an avalanche will increase.

Weather and Snow
Currently under partly cloudy skies trailhead temperatures are in the mid 20's °F while the highest peaks are in the high-teens °F. Winds are blowing lightly from the north gusting to the teen's MPH at the lower ridge-lines and blowing from lightly from the west-northwest gusting to the teen's MPH at 9,000'. There was another 1"-2" of new snow overnight bringing storm totals to 6"-11" of snow and .70"-1.20" water.
Today, look for partly cloudy skies with increasing clouds and precipitation this afternoon. Temperatures are forecast to be 32-38°F with winds blowing from the north-northwest 10 gusting to 15 MPH at the lower ridge-lines and 20 gusting to 25 MPH at the 9,000' ridge-lines. Look for a trace-1" of new snow with the off chance of 1"-3" and up to .30" water in select areas with increasing snowfall rates and winds this afternoon. There is a chance of lightning with the storm passing through. The freezing level should stay around 5,000' which means that with cloudy skies and colder temperatures the snow surface will stay soft making for excellent travel today.

Recent Avalanches
Yesterday, there was a report of a new snow avalanche in the Chilly Peak Slabs near Ben Lomond. Further north in the Logan Area mountains there were reports of rider triggered soft slab avalanches that were 6"-7" deep and 70' wide.

Avalanche Problem #1
New Snow
Today, it will be more difficult but not impossible to trigger a new snow avalanche failing on a density change within the newest snow. Any new snow that comes in this afternoon will be sensitive to backcountry travelers on steep slopes. IF the slope has had any wind affect it will be much more sensitive and like we saw yesterday you may be able to trigger soft slab avalanches 8"-10" deep breaking above you.
When an avalanche breaks above you vs at your skis or board it is more dangerous because you are now part of that avalanche and have less control over how you move through that terrain. Soft slab avalanches have enough power and oomph to take you of your feet and in terrain where they have the potential to gather more snow debris, piles can be quite deep.
Avalanche Problem #2
Normal Caution
Springtime in the mountains. What this means is that like the last weekend at your favorite ski resort most anything goes. You may see new snow avalanches, wind-drifted snow avalanches, wet snow avalanches, green-housing (filtered sun creating rapid warming of the snowpack at all elevations and aspects), glide avalanches, and thunder snow.
It's the time of year when it's easy to fall back on heuristic traps based on past experience, particularly familiarity. Keep your head about you when traveling in the mountains as even a small avalanche could have real consequences. Read more about heuristics and decision making from local avalanche researcher Ian McCammon HERE.
