The chances of loose-wet avalanches due to the Sun will be the wild card today. Clouds are forecasted to be increasing as the day goes on? Temperatures last night at the Granite weather station (7600ft) hovered around, and barely dipped below freezing. Today, with the lack of sustained freezing, possible solar radiation, and a high temperature near 7600 feet of 37 degrees, we are still going to be thinking about loose-wet avalanches.
Wind slabs around the advisory area have continued to stabilize over the last few days due to mild temperatures, light winds, and a lack of loose snow for transport. That being said, there is a lot of country out there and wind slabs still exist on shady, steep, leeward, and/or cross-loaded slopes. Before committing to any large slopes today, evaluate smaller slopes with similar elevation, aspect, and slope angle to see if any wind slabs are still lingering. On steep slopes on the north half of the compass, where wind slabs are most likely to exist, even a small ride from an avalanche could beat you up pretty good. Think about where that slide would take you. Are you riding above gullies, trees, or cliffs?

Dave and Kent were fortunate enough to take a flight over a good chunk of the advisory area on Monday with a local friend and pilot. There were quite a few impressive slab and loose snow avalanches from last weeks storm cycle around the mountains above McCall (pictures below). They also got to fly over and get a better look at the accident site from Saturday's cornice fall avalanche. Saturday's accident is a good reminder to always be thinking of what could happen/would happen. Example being. The side that people were snowmobiling on the terrain is mellow and travel looked to be easy due to supportable snow. However, there are quite a few tracks that were traversing out on to the cornice (pictures below) that is above a large cliff, and above a drainage that is not easy snowmobiling. And as it turned out, not an easy place to perform a rescue. Third picture down is a fly by of accident sit from Saturday's cornice fall avalanche. Look at where the tree line ends. Use vegetation and rocks as clues to where a cornice begins and ends.
