The National Disaster Risk Management Office is warning people to stay away and refrain from attempting to cross or swim in flooded areas.
They are also saying for people to contact the Fiji Police Force or the National Fire Authority should they need assistance to move to higher ground.
The NDRMO says roads may become slippery, creating hazardous and a higher risk of accidents, avoid flooded areas, delay non-essential travel, and use alternative routes where possible.
They say for households to be prepared and for children to be supervised at all times, look out for neighbours especially the elderly and those with special needs.
