A cyclone alert for Rotuma has been issued by the Fiji Meteorological Service.
The service is monitoring a tropical depression labelled TD12F which at 11am today was located about 160 km northwest of Rotuma.
The system is now moving southeast at about 5km/hr towards Rotuma and is expected to intensify to a tropical cyclone in the next 6 to 24 hours.
