South, southwest, and southeast winds over the last few days have added a new round of thin wind slabs in the upper elevations. Most of the wind transported snow has accumulated on the northerly aspects falling on older windslabs that were formed earlier last week. Some of these older windslabs ran naturally on Tuesday and were able to "step down" into deeper layers below. Watch for sculpted or stiff wind board on the windward aspects and rippled, chalky or hollow feeling/sounding pillows and drifts on steep leeward aspects. You should also be aware that due to the moderate to high winds last week, some of the older wind slabs may be found well below the ridgelines on leeward terrain. Practice safe travel protocols, and expose only one person at a time in wind loaded avalanche terrain.
Friends of the Payette Avalanche Center needs YOU! Come join us on Tuesday January 3rd at Idaho First Bank in McCall at 6 pm for an annual membership meeting. This meeting is open to the entire snow loving community, and we need to hear from you on how the Payette Avalanche Center should grow into the future.
Did you know: Only a small portion of our operating budget comes from the Forest Service, we RELY on the the Friends of the Payette Avalanche Center to help finance the forecasts that you use and the equipment we use to gather the information. Our forecast sleds are overdue for replacement and we rely on these as important tools to provide reliable avalanche advisories to the public...don't let your local avalanche center end up with a pile of melted metal, plastic, and rubber on the side of the road! Come out and support your FRIENDS and get involved Tuesday night or make a tax deductible donation online.
Low of 10 degrees overnight. Light winds out of the south southeast. 1 to 3 inches new very low density snow around the advisory area.
