The national weather forecasting centre in Nadi has forecast that a trough of low pressure remains slow moving over Fiji.
And it has advised of associated clouds and showers that are expected to affect the group until Thursday later this week.
As for the forecast to midnight tomorrow, expect occasional showers and few thunderstorms over Vanua Levu, the eastern parts and interior of the larger islands.
It has also forecast cloudy periods with afternoon or evening showers and isolated thunderstorms elsewhere.
The weatherman says isolated heavy falls are possible and that localised heavy falls may lead to flash flooding of low-lying areas.
