An Avalanche Watch is in effect for the Park Range. Heavy snow and strong winds will create very dangerous avalanche conditions during the day on Tuesday, lasting through Wednesday morning. Avalanches will break wide across terrain features and run long distances. Many will run naturally. Travel in, near, or under avalanche terrain is not recommended on Tuesday.
On Monday, you can trigger avalanches on weak layers buried about three feet deep. It is getting harder to trigger avalanches on this layer, but if you find a weak spot, you could trigger a large, dangerous avalanche. Shallow slopes with many trigger points will be the most hazardous slopes. Multiple people could ride a slope before it is triggered and you may get no feedback like cracking or collapsing. If you travel on slopes with a weak layer, lower-angle planar slopes without trigger points will reduce your hazard, or just avoid slopes with a weak layer altogether.
