Fiji's Metservice says people need to continue monitoring water levels, especially at high tide, which is due at about 6pm.
The trough causing heavy rain and flooding in Fiji is expected to last for the rest of today, and begin to ease tomorrow morning.
A senior meterologist, Amit Singh, says by mid-morning, there had been 145 millimetres of rain in the past 24 hours.
"People need to be careful especially during the tides, high tide. Last high tide was around 6 in the morning, and the next one will be around 6 in the evening."
Amit Singh says the trough is also causing heavy rain in Tonga - which should also ease early tomorrow.
He says the forecast suggests another wet weekend for Fiji, starting from late Friday.
