Stability of a vortex was studied in a modified cellular automation model. The model includes dependence of wave velocity of excitation interval and front curvature. Two kinds of vortex instability are observed, as found also in models based on partial differential equations: meandering of the vortex and vortex drift in a heterogeneous medium.
