Good morning, this is Brett Kobernik with
the
Current Conditions:
This mornings weather
conditions almost mimic yesterday’s. Mountain
temperatures remain inverted with overnight lows in the mid-to upper 30’s above
9500 feet. On the backside of the ridge
of high pressure, winds are out of the south and southwest averaging 15-25mph
but show signs of increasing over the last few hours with gusts into the 60s at
the most exposed locations.
Snowpack and Avalanche Conditions:
Surface conditions
range from supportable melt freeze crusts on southerly aspects to dense settled
powder and wind blown snow on the northerly aspects. No avalanche activity was reported from
yesterday. This was due to the fact that
I received no backcountry observation this morning.
So, if a tree falls in
the woods……….?
We tend to overlook persistent
weakness during periods when no one is out getting collapsing or
avalanching. But, since no one is
triggering avalanches, does this mean the weakness is done with? Not necessarily. While many slopes have undergone significant
settling, I imagine that people could still find a slope that has a slab with
enough tension still to crack, propagate, and avalanche. Like the message we’ve been preaching over
the last week, you’ll find these suspect slopes on upper elevation northerly
aspects.
Bottom Line:
Most slopes have a LOW danger today.
However, a MODERATE danger still
exists on northwest, north and northeast facing slopes above 9,500 feet that
are steeper then 35 degrees.
Mountain Weather:
Under southwest flow
we’ll see cloudy skies with southwest winds in the 15 to 25 mph range gusting
into the 40s along the ridges. Gusts
will be around 60 at the most exposed locations. 10,000’ temperatures will be in the upper
30s. Wednesday looks like a repeat of
today with slight cooling. On Thanksgiving
we’ll have a chance for snow with a short wave trof that moves through. This appears like it won’t be a big event.
Announcements:
The next FUAC fundraiser will be at Brewvies. “The Anomaly” by TGR
is playing on Dec 7th, with two showings, at 7pm and 9pm. Advance tickets are available.
