Our Avalanche problems have flip flopped over the last few days quite a bit with some extreme weather changes but wind seems to be the constant factor in our snowpack this year. We found quite a few newly deposited wind slabs in mostly Northerly terrain over the last two days but also saw evidence of loading and crossloading on E and W aspects as well. The wind slabs that have formed are mostly shallow but you may still find some high elevation areas that are harboring older and deeper wind slabs in the dense snow deposited by the wet storm that we got mid week.
Large cornices have also formed on most of our ridgelines. Cornices should be avoided right now as they are very large and and extremely unpredictable after the wet storm this week. We had a close call yesterday near Black Tip with a large cornice failure under the weight of a snowmobiler that was taking pictures near the edge of one of these monsters when it broke.
You are going to see a lot of avalanche debris if you are in the mountains over the next few days,as always, please send us your pictures or observations.
Our snowpack just experienced some major trauma in the form of high elevation rain. We experienced the largest natural avalanche cycle of the winter and now the snowpack has begun healing itself with the re-freezing process that started Friday as a cold front moved in. The upper portion of the snowpack has already formed a supportible crust in most places but you may still find some punchy, breakable areas in the middle elevations. Avoid steeper terrain until the snowpack has completely re-frozen.
Day time warming is going to be the next weather factor to keep in mind. Temperatures during the day will be climbing starting today and getting progressively warmer each day through the week. As we pass the freezing mark, expect to see small wet, loose avalanche activity rising especially on steep slopes that are getting direct sun.
Warren Wagon snowmobile route is Closed right now. A creek between Fisher Creek and Deep Creek flash flooded/experienced a debris flow that has blocked the road with snow and woody debris as well as cutting a deep channel through the snowmobile route and is impassible. Acess to the Copet Creek Route is still open. The Brush Creek route is now open and should be groomed tonight. Lick Creek Road had water flowing across it yesterday afternoon as well near the Forest Boundary.
Snowmobiler/Snowbiker Travel Restrictions: a quick reminder that the Granite Mountain Area Closure is now in effect, please respect Snowcats operating in this and nearby areas. In addition there are other areas on the Payette National Forest that are CLOSED to snowmobile traffic including Jughandle Mt east of Jug Meadows, Lick Creek/Lake Fork Drainage (on the right side of the road as you are traveling up canyon), and the area north of Brundage Mt Ski area to junction "V" and along the east side of Brundage and Sergeants' Mts. with the exception of the Lookout Rd( junction "S"). Please respect these closures and other users recreating in them. Winter Travel Map(East side). You can download the map to the AVENZA app on your phone, and know your exact location while you are out riding.
The Friends of the Payette Avalanche Center (FPAC) needs YOU! We are in desperate need of more user support and financial assistance. The avalanche forecast is not a guaranteed service, and is in jeopardy of dwindling down to only a couple of days a week in the near future. Please help if you can by clicking the DONATE tab above. If you value this life saving information, make a donation or help the FPAC in raising funds for the future.
If you are out in the mountains right now, you will see the aftermath of the warm storm that rolled through the West mid week. A widespread natural wet avalanche cycle occurred on steep terrain and several large slab avalanches failed in windloaded Northerly terrain. If you see large avalanches, take the time to note the location and send us a picture.
Yesterday, McCall Fire and Rescue assisted by riders from C&M Backcountry Rentals and Two Bear Air responded to an accident involving a large cornice failure near Black Tip that injured a rider after a long fall into steep rocky terrain where he was apparently buried by the debris of the cornice failure. He was not on his sled but was standing on a large overhanging section of cornice at the ridgeline. We will be collecting information today and tomorrow and release details as we know more.
