The Nadi Weather Centre has warned of more heavy rain tonight in the western, northern and eastern divisions of Fiji after flooding today severely disrupted life in the west.
Nadi town was under one metre of water during the day and the Nadi Back Road bypassing the town was closed.

Disaster authorities have set up four evacuation centres in Nadi.
Troops have joined police in providing security in Nadi for the night and in helping people across flooded roads and bridges so they can reach home tonight.
