You could trigger a large avalanche in weak snow close to the ground on northerly and easterly aspects. You can easily start an avalanche from below or from a distance, and observers have reported avalanches running into usually “safe areas.” Reassess all your usual travel routes. You may not see red flag signs of instability like cracking or collapsing before you trigger a large avalanche. Avoid rounded pillows of wind-drifted snow where triggering the surface snow will likely cause the avalanche to step down and fail at the ground. On aspects with a buried weak layer, you can find safer riding on slopes less than about 30 degrees unconnected to steeper terrain.
