morning, this is Evelyn Lees with the Forest Service
Center with your
backcountry avalanche and mountain weather advisory. Today is Thursday, March 04, 2004, and it’s 7:30
a.m. This forecast is brought to you in
partnership with the Friends of the Utah
supported in part by the Uinta Brewing Company.
The first of two weather
disturbances is sliding across northern Utah
this morning, and a couple of inches of light snow have fallen in the
mountains. Winds are from a westerly
direction, in the 10 to 15 mph range. They
should rapidly shift to the northwest and may increase as the front passes this
morning. Temperatures are in the low
teens at 10,000’. Any slope catching
even the least bit of sun, including flat and low angle slopes, now has a crispy,
brittle to hard crust. The shady,
northerly facing slopes are a welcome contrast, with excellent reserves of dry
There was an extremely close call in Daley Canyon
yesterday. Bruce was looking at the site
of last week’s fatality when he noticed a very recent avalanche, complete with
tracks leading into it and a burial hole.
The slide was on a northerly facing, 41 degree slope, at 7600’. It was 120’ wide, up to 3’ deep, and failed
on the January dry spell facets that were capped by a thin crust. (See
photos and information.) A similar 3 foot deep slide was triggered Monday
in the Uintas by the third skier on a northwesterly facing slope at 8500’.
These deep slides are being triggered on slopes with
a shallow snowpack, generally less than 4 or 5 feet thick, which are plagued by
a weak layer of January facets. If you
have ski poles, try flipping them over and jab the handle into the snow. If the pole goes in full depth with out too
much trouble, you are most likely in a shallow snow pack area. These dangerous areas are most widespread on the
eastern side of the Park
and in the Uintas. But pockets of thinner,
weak snow exist throughout the Wasatch on slopes that are steep and rocky, that
have already slid this winter, are northwesterly facing or at mid elevations.
The avalanche danger will increase this afternoon or
tonight, whenever the northwesterly winds start to drift snow. These winds will be predominately loading east
and southeasterly facing slopes, which have layers of weak crusts and facets. So as always, avoid any new drifts of wind
blown snow on steep slopes.
More information has determined the enormous climax
slide off the southwest facing side of Buckley peak in the Provo area mountains
most likely occurred late Sunday.
Line for the Wasatch Range, including the Salt
City, PROVO AND OGDEN AREA
The avalanche danger is MODERATE
on slopes steeper than 35 degrees. While
there are only isolated places where a person could trigger a slide today, if
you do it will likely be deep and dangerous.
The avalanche danger is closer to CONSIDERABLE in the Uinta and
eastern Park City mountains. You can find plenty of areas with LOW
avalanche danger today on slopes less steep than about 35 degrees.

morning’s cold front is expected to produce 3 to 6 inches of snow in the mountains.
Winds will shift from the west to
northwest, and may increase into the 15 to 25 mph range. High temperatures will only be in the low 20’s
at 8,000’ and near 10 at 10,000’. A
stronger disturbance crossing northern Utah
tonight will generate steady snowfall, accompanied by strong northwest winds. 3 to 6” of snow expected tonight, with areas
favored by northwest flow receiving up to 10 inches. A short break on Friday afternoon will be
followed by a windy and unsettled weekend, with periods of light snow.
