Good Morning.† This is Bruce Tremper with the
With a mighty one inch of new snow overnight and three in the past 24 hours, this weak storm isnít impressing me much.† Most of the energy from the storm is heading south of us and I donít think weíll get much more.† The south facing slopes are sun crusted, thereís some wind damage along the ridge tops and the northerly facing slopes still have some nice powder, but it has gotten thicker from the very nice snow yesterday.†
We heard of four more human
triggered avalanches that occurred in the backcountry yesterday.† A skier triggered a steep wind slab in
Although the avalanches are
harder to trigger than a couple days ago, as you can see, things are still plenty
This doesnít mean that itís
dangerous everywhere.† The hot tip for
the day is to do one of three things:†
First, the south facing slopes are significantly more stable than the
north facing ones because the new snow fell mostly on bare ground or snow
stabilized by the heat of the sun. †The downside
is that these slopes will be rocky and sun crusted. †Second, if you must go the steep slopes on shady
aspects, you can have a good time on slopes that slid during the storm, which
should be fairly safe as long as you donít tickle the snow hanging above the
fracture line. †The bad news is that itís
hard to tell what slid during the storm and what didnít because most of the
slides are now covered up by a foot of new, and wind-blown, snow. †Also, these slopes tend to be rocky because
some of the snow was removed during the slide.†
†Finally, you can go to a slope on
a shady aspect that did not slide during the storm.† The bad news is that anything steeper than
about 35 degrees will likely slide so youíll have to diligently wa
Bottom Line (SLC,
The avalanche danger is CONSIDERABLE today on all steep slopes with wind drifted snow.† The danger is also CONSIDERABLE on northwest, north, northeast and east facing slopes above about 7,000í steeper than about 35 degrees, and MODERATE to LOW on steep southeast through southwest facing slopes or on steep slopes that slid during the storm.
Tonight at is the winter solstice, meaning that today is the shortest and darkest day of the year.† With most of the energy from this storm heading south of us, weíre left with the worst parts of the stormójust poor visibility, cold temperatures and very little snow.† Today expect temperatures quite chilly in the single digits along the ridge tops and rising into the teens later in the day down at 8,000í.† Ridge top winds should be 20 mph from the west this morning and becoming light and variable by afternoon.† Looks like a few lingering clouds on Sunday and clearing out on Monday.† Next chance for snow is about next Thursday.†
