A heavy rain alert is now in force for Vanua Levu and Yasawa.
The Nadi Weather Office says the tropical disturbance close to Niue has weakened and remains slow moving to the far east of Fiji.
However, associated active trough with cloud and rain is drifting towards the country and expected to affect the northern parts of the country from later today.
Meanwhile another shallow tropical disturbance has developed to the north of Fiji near Rotuma along the trough that extends from the other tropical disturbance.
The second disturbance is currently slow moving and lies in a favourable environment for further development, intensify and gradually move southwards towards the country.
Director Ravind Kumar says in anticipation of the active trough moving over the northern parts of the country, a heavy rain alert is now in force for Vanua Levu and Yasawa.
Expect cloudy conditions from today with showers increasing to rain, becoming frequent and heavy at times as the trough moves over the northern parts of the group tomorrow.
Rain is expected to gradually spread to other parts of the country as the active trough and the second tropical disturbance moves closer to the group this weekend.
The active trough has a potential to produce rainfall exceeding 100mm in 24 hours in areas under heavy rain alert.
Localised heavy rain may lead to flash flooding, initially over the low lying areas.
