 During October 20, the JTWC and the FMS started to monitor a tropical depression, that had developed within the South Pacific Convergence Zone to the north of Temotu Province in the Solomon Islands.Over the next day conditions surrounding the system rapidly became favourable for further development, with convection starting to wrap into a well defined low level circulation centre.As a result, the depression rapidly developed further and was named Xavier by the FMS during October 22, after it had become a category 1 tropical cyclone on the Australian tropical cyclone intensity scale.
