The Nadi Weather Office said the tropical depression which was located over Northern part of Vanuatu yesterday has moved southeast and was located about 680km West of Nadi at 7 o'clock this morning.

Director Rajendra Prasad said the system has been influenced by increasing upper level wind shear and as such has not gained any real tropical cyclone characteristics, however it is still expected to deepen as it continues to move Southeast and is expected to develop into a deep depression South of Fiji.

He said the system is expected to pass about 400km Southwest of Kadavu at its closest point tonight.

Prasad said for Fiji expect strong gusty northwesterly winds today and tomorrow especially over the Western and Southwestern parts of Viti Levu, Kadavu, Vatulele, Beqa including Yasawa and Mamanuca group.

He said seas are expected be very rough with heavy swells developing.

The Weather office warns that rain is expected to be widespread with more frequent and heavier falls in the western and northwestern parts of the larger islands and flooding of low lying areas, rivers and streams is expected especially in the Western division.
