Good morning, this is Bruce Tremper with the
My suspicions about
this storm yesterday proved well-justified.
It was yet another storm of huff-and-puff-but-not-much-fluff. A mighty 2-5 inches of pasty snow fell
yesterday but hey, at least the winds were blowing hard enough to tip over a
tractor. Yesterday’s ridge top winds
blew from the southwest, 35 gusting into the upper 50’s for much of the day. The places that get hit hard from the
southwest winds had a lot of damage, such as the
Snowpack and Avalanche Conditions:
Yesterday not a lot of
people were out in the backcountry, but the hard working and cagy Bob Athey and
Mark White were able to intentionally trigger a hard slab on a wind-loaded side
in Days Fork at 9,500’. It broke 1-2
feet deep on faceted snow beneath a buried rime crust and stepped down into
deeper faceted snow. They were able to
trigger it from the flats near the slide. Photo
3 Also, all the ski resorts reported
widespread areas of sensitive, soft slabs on all the wind drifted slopes, but
for the most part, they were shallow and manageable. The exception was an explosive-triggered
slide in Daily Chutes near
Bottom Line for the
The danger is MODERATE on any slope steeper than about 35 degrees with
recent deposits of wind drifted snow less than a foot deep
soft slabs. The danger is CONSIDERABLE on slopes with wind drifts more than
a foot deep and hard slabs. You will
find pockets of these wind slabs along many of the upper elevation, wind
exposed slopes. The danger will be LOW in non-wind drifted
slopes with less than 4 inches of new snow.
Today the ridge top
winds will shift from the north to the northeast and they may pick up and blow
as strong as 30 mph with higher gusts, which will give us a whole new set of
wind slabs. We will get a few more light
snow showers this morning but probably won’t add up to more than an inch. We should have clouds hanging around the
mountains for most of the day. Ridge top
temperatures will be in the mid teens.
Skies should clear by tonight and we will have warmer temperatures and
clear skies for the weekend.
The extended forecast calls for clear weather through the weekend with a few high clouds on Tuesday and another chance for some snow about a week from today.
