Drivers are urged to exercise extreme caution while driving and remain vigilant of surface flooding.
The Fiji Roads Authority reminds drivers to avoid areas that are prone to flooding and never attempt to drive through floodwaters.
FRA says drivers should reduce their speed, maintain a safe distance from other vehicles, and use their headlights to enhance visibility.
