Temperatures in the upper elevations have been above freezing for more than 24 hours, and rain has fallen all the way up to 7,000 feet. Wet, loose activity in the form of rollerballs and point releases are possible, and so are human triggered wet, loose slides in terrain steeper than 35 degrees. The snow surface should adjust, and stabilize some as temperatures cool down this evening.
Fresh wind slabs will form today, and this evening as we recieve 2-4 inches of snow along with moderate winds out of the West-Southwest. Fresh slabs will form on NW, N, NE, and East aspects. Watch for signs of sculpting on the snow surface, hollow or drummy feel, or stiffer snow. Tonight the winds will gust around 32 Mph which will do a great job adding to our wind slab problem.
Ladies, Don't forget about our Diva Avalanche Class this weekend at Tamarack Resort. Show up early for yoga and coffee or come just for the class. Stay late for Happy Hour at Seven Devils Pub! Suggested donation of $10 for the Friends of the Payette Avalanche Center.

Based on our stability tests, and lack of recent avalanche activity on our buried surface hoar (about 110 CM deep), we are phasing the deep slab/persistent weak layer problem out of the advisory for now. If (or when) temperatures allow melting water to percolate through the snowpack we could see this particular boogeyman make another visit to the West Central Mountains. Keep this layer in mind if you are skiing or riding on protected northerly slopes with a steep, shallow snowpack because you could still be unlucky enough to find a trigger point for a large and unsurvivable avalanche.
Today snow levels are dropping back down to around 5500 feet, and we will see 2-4 inches of snow with moderate winds out of the West-Southwest...winds will gust around 32 Mph tonight in the upper elevations.
