Bad weather associated with the system over the past few days has caused major flooding in the country.
On Sunday, the National Disaster Management Office said a 35 year-old man from the western town of Tavua drowned while trying to cross a flooded river.
The office expects thousands more who live in Fiji's main island Viti Levu could be in danger as major waterways record increasing water levels, and river banks burst.
Over 300 people are taking shelter in evacuation centres around Fiji.
There are 28 evacuation centres open in the Western Division while 2 are open in the Northern Division.
