A Heavy Rain Alert is now in force for Yasawa and Mamanuca Groups, Viti Levu,
Kadavu and nearby smaller islands, and Lomaiviti and Southern Lau Groups.
According to the Fiji Meteorological Service, a trough of low pressure is expected to approach the group from the west and affect parts of Fiji from later Saturday.
This setup is expected to bring occasional rain, heavy at times, over the areas in Heavy Rain Alert.
Rain is likely to be significant in the afternoon, overnight or early morning.
Localised heavy falls could lead to flash flooding in low-lying and flood-prone areas.
There is a possibility of clear skies or sunny breaks in between the rain bands, especially during the early part of the day.
