Move to higher ground
Fiji's disaster office is advising people living in low-lying areas to move to higher ground as Tropical Cyclone Sarai intensifies.
It said all regional agencies are on stand-by to respond where and as necessary.
The office said heavy rain may lead to flooding of low-lying areas and coastal sea-flooding is expected during high tides.
The office is advising people in these at-risk areas to move to higher ground or local evacuation centres.
There are currently 63 people at evacuation points in Tokou Village in Ovalau, Matawalu Church in Lautoka and Marata Hall in Wailoku.
