Current Conditions:
Skies are clear this morning,
and temperatures have already warmed into the upper twenties to low
thirties. Winds have shifted to the
southwest, and are in the 10 to 15 mph range with gusts near 20. Turning conditions are best on northerly
facing slopes, especially in more wind sheltered areas, where you’ll find dense
spongy snow. Other slopes are a mix of sun
crusts, wind scour and wind drifts.
Avalanche Conditions:
It’s
almost unreal how fast the snow pack went from being extremely sensitive, with natural
activity on Monday, to being mostly stable by Tuesday, all in less than 24
hours. Yesterday, no avalanche activity
was reported from the backcountry. Even explosive
control work in backcountry-like areas at the resorts triggered surprisingly few
avalanches. A few small soft slab
pockets were released, plus one harder slab which was about 2’ deep, 50’ wide,
and ran on the buried surface hoar layer.
Some of these slides released near the ridges and others mid slope. Still, it’s not the day to be jumping with blind
abandon into every steep chute or slope.
There are certainly places out there where a person could still trigger
a slide, and caution should be used if you’re traveling on steep, shady, wind
drifted slopes.
Another
concern today will be the effect of the skyrocketing temperatures, forecast to be
10 to 20 degrees warmer than yesterday. As
the snow heats up on the steep sunny slopes and at the lower elevations, expect
roller balls and wet, loose sluffs. The
snow often heats up first near and below rock ou
Bottom Line (
The avalanche danger is MODERATE on wind drifted slopes steeper than about 35
degrees, above about 9,500. The winds
drifts are most widespread on north through east facing slopes. Other slopes have a generally LOW danger. As the day
heats up, the avalanche danger will rise to MODERATE on and below
steep, sunny slopes.
Mountain Weather:
The ridge is making its final stand today before another round of wind,
snow and colder temperatures moves into northern
