Tropical cyclone Odette developed from a tropical low pressure system on 8 April 2021 in the Indian Ocean off the north Western Australia coast. Odette weakened to a tropical low due to exposure to wind shear and was incorporated into the larger Tropical Cyclone Seroja system (the Fujiwhara Effect). The system moved to the southwest while rotating around TC Seroja.
