Headed up to the PC Ridgeline at about noon today, moderate snowfall on our arrival some breaks in the clouds through out the day. Noted 4 different slides in West Monitor and put them on the avy page. Seemed like the only avalanche activity was on steep wind loaded terrain with a hard bed surface underlying it, 36 degrees or steeper seemed to be the number but as the day progressed I think the new snow instabilities were subsiding, I don't think slopes without wind loading were suspect today, but I think Evelyn's considerable call was right on the mark, natural avalanches were occurring during the frontal passage with a spike in the winds and high PI rates.

FORECASTER NOTE: We started from Solitude and noted around 4 inches of new snow from the last 12 hour period, no wind effect. As we ascended Willows, we noted the new snow was layered (slightly inverted) from the wind. We then noted the natural avalanches in West Monitor and lowered our expectations to get into the big bowls. We worked over to South Monitor where there were some tracks down the east facing portion of the bowl. That wasn't enough to convince us of good stability so we started kicking cornices (good visibility with no one below) It quickly became obvious that things were already stabilizing and you needed a steeper slope to get a significant slab release. We got some cracking with the cornices but they would not run like the steeper portions of West Monitor which ran during the height of the frontal passage. We ended up getting some good skiing in South Monitor but not before doing our homework. - Kobernik
Main concern tomorrow will be heating by the sun on the low density snow
