A HEAVY rain warning is now in force for the whole of Fiji group.
A trough of low pressure lies just West of Fiji and approaches the group.
The Fiji Meteorological Services said associated cloud and rain would affect the Fiji group.
It says the low pressure will cause occasional rain, which may become heavy at times and few thunderstorms.
Rain is expected to become frequent from tonight.
The weather centre added that localised heavy falls may lead to flash flooding of low-lying areas.
