A vortex structure is predicted for Josephson-coupled superconductors in strong magnetic fields oriented near {ital ab} plane. The {ital c} axis component of the field forms an almost triangular pancake lattice inside the layers with the pancakes arranged in a zigzag structure along the {ital c} axis. This zigzag structure results in a sharp increase of the {ital c}-axis critical current and plasma frequency when the magnetic field deviates from {ital ab} orientation. These predictions are confirmed experimentally. {copyright} {ital 1996 The American Physical Society.}
