Good Morning.† This is Bruce Tremper with the
With a big, fat full moon in
a clear sky, both last night and tonight, these are great nights to get out in
the mountains and enjoy life.† Itís been
mighty blustery these past few days, especially Wednesday, with strong winds,
mostly from the northwest. †This has
decorated the above-tree line ridges in a Martian sandblasted decor.† Thereís no lack of sun crusts on the slopes
that face the south half of the compass.†
Believe it or not, thereís still lots of nice,
soft, dry, recrystalized snow that could pass for
The main avalanche problem today is the surface layers of wind drifted snow.† These ďwind slabsĒ, as we call them, tend to be hard and hollow-sounding but they can be soft as well.† Like a rattlesnake, they almost always warn you of their presence.† Many of them crack under your weight, sound hollow, feel slabby and most are hard and stubborn.† They have a smooth, rounded, chalky, wind-drifted appearance and if you find one on a steep slope, they are definitely to be avoided today.† Much of the above-tree line terrain is covered with them while others are very pockety.† One spot may be perfectly safe while another a few feet away will crack under you and take you for a ride.
The second, and much less serious, problem is our old enemy from throughout this winteróthe deeply buried layers of weak, sugary, faceted snow.† These layers have significantly settled and adjusted to their load in most places and itís been nearly a week since any people have triggered an avalanche on this layer.† Without any wind slabs on top, I think human-triggered avalanches on the deep layers will be quite rare today, but with a wind slab on top, an avalanche could easily have enough punch to step down into these deeper weak layers, making a much larger and more dangerous avalanche. †
Bottom Line (SLC,
There is a MODERATE avalanche danger on any steep slope with recent deposits of wind drifted snow. †This means that human-triggered avalanches are possible.† In terrain without wind drifts, there is generally a LOW danger with localized pockets of MODERATE danger on slopes facing the north half of the compass, plus east facing slopes, above about 8,500í that approach about 40 degrees steepness.†
Bottom Line (
There is a CONSIDERABLE avalanche danger on steep slopes with recent deposits of wind drifted snow at elevations above timberline. There is also a MODERATE danger of triggering a deep slab avalanche on slopes facing northwest, north, northeast and east, above about 8,500í that are steeper than 35 degrees.† On south facing slopes without recent deposits wind deposits and slopes less than steep than 30 degrees, the avalanche danger is generally LOW.†
weather continues with the same as it ever was.†
Continued clear with scattered high clouds going by at
times and another beautiful full moon tonight.† Ridge top winds will blow around 20 mph from
the northwest this morning, swi
As for the extended forecast: we will see some increasing clouds on Monday in advance of a weak system going mostly north of us on Tuesday.† Then, we will have another slightly stronger system on Thursday and Friday.† I hope Iím wrong, but donít expect too much from these systems as we are still stuck under a ridge and these systems have to break through the ridge to reach us, which tends to keep them on the wimpy side.† We still donít see any significant snow in the forecast until at least the end of the month.
To report backcountry snow and avalanche conditions, especially if you observe or trigger an avalanche, call (801) 524-5304 or 1-800-662-4140, or email to [email protected] or fax to 801-524-6301.† The information in this advisory is from the U.S. Forest Service, which is solely responsible for its content.† This advisory describes general avalanche conditions and local variations always occur.
Ethan Greene will update this advisory by on Sunday morning.
