Good morning, this is
There will be a benefit for the Friends of the

Under mostly clear skies this morning, mountain temperatures dipped into the single digits and winds picked up into the 15 to 25 mph range from the northeast with the higher elevations around Ogden showing the strongest winds in the 30 to 40 mph range gusting into the 50s. Soft powder remained on the surface Monday with wind crusts forming on some aspects at the upper elevations. These wind affected areas will probably be more widespread today with the shift in wind direction.
No avalanches breaking
into old snow were reported from the backcountry on Monday. Can
you still trigger one? Most experienced
people say “oh yeah” and might even point you to an area where they know you could get a slide to
release. Some collapsing into the older
snow was reported from Monday. Also,
there were reports of some sluffing of the newest snow on steeper aspects as
well as some shallow wind slabs that released naturally in the
For today you will still want to avoid the steeper northerly aspects as the snow structure is still suspect. Weaker faceted snow under the last couple of snow storms still has the potential to collapse and release an avalanche.
With the switch in wind direction, wind affected areas will be more widespread today at the upper elevations. Watch for cracking which is an indicator of freshly formed drifts. My guess is that you’ll probably be able to find these shallow wind slabs and crusts on many upper elevation aspects today. These probably won’t pose a great threat but you should be aware that they’re around.
avalanche danger is MODERATE on upper
elevation northerly facing steeper slopes.
I cannot stress enough that the consequences are quite severe if you do
trigger an avalanche in this terrain. Human
triggered avalanches are possible on the upper elevation northerly facing
steeper slopes in the
Today we’ll see more clearing as the day progresses. Temperatures will remain fairly cold with highs in the teens along the upper ridges. Northeasterly winds will continue but will slow as the day goes on. It looks like we’ll see a minor weather disturbance late Wednesday with a better looking system Thursday night into Friday which could produce snow.
