Snowpack Summary
Around 40 cm of new snow at Parkers ridge in the past 48 hours with moderate to strong south west winds. Alpine and tree-line areas are now gaining enough snow for avalanches, particularly in leeward alpine bowls, gullies, and around ridge lines.
Avalanche Summary
Road patrol observed one small loose dry avalanche running in a steep narrow gully, no alpine or tree line observations due to poor visibility all day. There have been reports of smaller isolated wind slabs in alpine features over the past week, but not a lot of people are out in the mountains so take that into account in your decision making.
