The cyclone developed in eastern Solomon Islands and is moving in a southeasterly direction to waters between Vanuatu and Fiji.
The category one cyclone was situated about 280 kilometres northnortheast of Anuta early this morning.
The east of Solomon Islands is being warned to expect heavy rain, gales and high seas in the next 24 hours.
Although the weather is reportedly calm in Port Vila, sailings from the town and from Luganville in Santo are on hold until further notice.
