In sintesi

The hazard ratings are better by definition but the consequences of exposure to large overhead hazard with such a weak basal layer is real.

    Windslabs are being encountered in isolated areas at Treeline and more widespread in the Alpine. Ridgelines, gullies and crossloaded features should be treated with caution and in steeper terrain avoided.
