A tropical low has been analysed in the region and is likely to intensify into a tropical disturbance within the next 24 to 48 hours.
Weather models indicate the shallow low-pressure system is moving closer to Vanuatu, where environmental conditions are favourable for further development.
These include strong upper-level divergence and increased low-level moisture convergence.
Fiji Met states the system is forecast to track southeastwards over open waters between Fiji and Vanuatu over the next 48 to 72 hours.
Despite the favourable conditions for some intensification, forecasters say the likelihood of the system developing into a tropical cyclone within the next 24 to 48 hours remains very low.
Authorities will continue to closely monitor the system and issue updates should there be any significant change in its development or track.
