Hello
and good morning, this is Toby Weed of the
Current Conditions:
Warm southwest winds
will heat things up in the backcountry today, and increasing clouds could trap
the heat and allow it to affect the remaining nice upper elevation snow. You’ll find a variety of softening crusts and
moist snow in different stages of melt varying greatly depending on elevation
and slope aspect. A couple cold fronts from
storms passing to our north will bring cooler temperatures, but you’ll have to
head up to the Teton or
Southwest winds picked up steam yesterday evening and they’ve
been steady and fairly strong overnight, with the CSI weather station on
Avalanche Conditions:
Overall, it was a quiet weekend avalanche-wise in the mountains of
Significant wet avalanches are possible on steep slopes today as warmth
turns the fresh surface snow into slush.
Some or the huge cornices in the region could become active with gravity
and heating, so you’d be wise to stay out from under ‘em. You might find even smallish wet avalanches
entraining lots of mass and traveling far.
It is difficult to tell exactly when or if wet avalanches will occur,
but it’ll be a good idea today to avoid and stay out from under steep slopes
with melt-saturated snow at all elevations.
Triggered
wind or persistent slab avalanches are possible on steep upper elevation slopes. Wind slab avalanches are most likely on steep
northeast facing slopes or those with significant deposits of recently drifted
snow. Isolated persistent slabs are possible on very steep slopes above 8000’
in elevation and facing the northern half of the compass. Many avalanche slide paths in the area are
well filled-in and smooth, so even relatively small wind slab avalanches might
run far or fast.
Bottom Line:
There’s
a MODERATE avalanche danger in the backcountry,
and you could trigger avalanches on some slopes steeper than about 35 degrees. Wet avalanches will become possible at all
elevations in the
Mountain Weather: Today will be the warmest day for a
while in the mountains. Storms passing
to our north will bring cooler temperatures starting this afternoon. A sharp cold front will bring some heavy snow
to the area on Wednesday, but the storm could be a quick hitter. Cooler and somewhat cloudy weather is
expected for the balance of the week and another cold front is possible for the
coming weekend

I'm very interested to
know what you're seeing out there. Please e-mail observations to me
at [email protected] or leave me a message at 755-3638, especially if you see or
trigger an avalanche in the backcountry. We keep all observations confidential.
