Video taken in a town in Fiji shows the full extent of Cyclone Keni's destructive flooding.
The footage, which was posted to Twitter, shows a commercial street in Ba Town underwater. A person can be seen trudging through the floodwater, indicating that in some places the water is about a foot deep.
Disaster management officials say 3600 people have taken shelter in evacuation centres as the category 3 storm lashes the country.
The director of the country's National Disaster Management Office, Anare Leweniqila, says the most high-risk areas are in the west of the country, which were flooded by rainfall from another cyclone just over a week ago.
Mr Leweniqila told Newshub the towns of Ba and Rakiraki are underwater again, roads have been cut off and access to both areas is restricted.
Over Easter weekend, category one Cyclone Josie brought significant rainfall to the western division and killed six people, who were swept away in floodwaters.
Mathew Bolaitamana from the Red Cross says despite warnings about the latest storm, some people have failed to move to safer ground.
He says 10 families from Lovu, a low-lying area in the western district of Lautoka, have been told by disaster officials to leave their homes as floodwaters continue to rise.
On its current path, Cyclone Keni will pass across the southern islands of Kadavu and the Ono-i-Lau island group later today before heading offshore and losing strength.
Currently, 3600 people are seeking shelter from Cyclone Keni at 66 evacuation centres around the country.
