A system and method reduce vibrations in a blade mounted on a hub of a wind turbine rotor when the rotor is in a limited yaw capacity state with a defined allowable yaw sweep. An allowable yaw sweep is defined for the limited yaw capacity state. A sensor in communication with a controller monitors for vibrations in the blade with the rotor at an initial yaw position. Upon detection of vibrations, the controller determines a yaw sweep sector that is within and less than the allowable yaw sweep and issues a command to a yaw system to yaw the rotor in a continuous back and forth manner in the yaw sweep sector. The controller continues to monitor for vibrations in the blade during or after the continuous yawing of the rotor and stops the continuous yawing of the rotor when the blade vibrations reduce to below the threshold level.
