Yesterday, avalanche control work produced
just a few sensitive, soft, wind slabs on steep, wind loaded slopes but down
out of the wind, the snow seemed to plaster in place fairly well. One person in Days Fork kicked off a wind
slab 20’ wide and 1.5’ deep and dug into the bed surface to keep him from going
down. It was a very wind loaded, 40
degree, north facing slope. They
recognized it was wind loaded but they were trying to get around it. We also found that the snow cracked easily on
wind drifted slopes and we were careful to avoid steep, wind drifted terrain (PHOTO). With continued heavy snow today and continued
20-30 mph ridge top winds from the northwest, you can expect to find some
sensitive soft slab avalanches on steep, wind loaded terrain. When it starts snowing harder this afternoon,
check how well the new snow bonds to the underling snow as it comes down. Also, with all this weight added over the past
week, we always have to suspect deeper avalanches breaking down into deeper
weak layers. Although the deeper
snowpack is quite solid in the Tri Canyons, it’s shallower and weaker in
The avalanche danger is CONSIDERABLE this morning on steep, wind drifted slopes and MODERATE on non-wind drifted slopes. With additional snow and wind this afternoon the danger may rise to CONSIDERABLE even on non wind-drifted slopes as well.
The northwest flow will cool and destabilize throughout the day, so we expect heavy snow especially mid day through afternoon, which could pile up as much as a foot of snow by this evening and perhaps 6 more inches overnight. Ridge top temperatures will cool to the mid teens by afternoon with ridge top winds 20 with gusts to 30 mph from the northwest. Down at 8,000’ temperatures will be in the mid 20’s.
We should have lingering clouds on Friday but not much snow. By Saturday, ridge top temperatures will rise dramatically to near freezing and we will have to watch for wet avalanche activity within the new snow. Then, we have another quick-hitting cold front for Saturday night, which should give us another 8 inches of snow.
