EXTENSIVE floodwaters that inundated centres in the Western Division could have been caused by shallow rivers, creeks and waterways.
This is the view of acting divisional roads engineer Western Munsami Naidu.
"More than 30 roads are now closed and this flood is going to cause a lot of damage to roads we were just beginning to repair as a result of the January floods.
"An important contributing factor to the floods is the fact that most waterways were made shallow by the floods earlier this year with increased silt and debris and the heavy rainfall caused rivers and creeks to flood very rapidly."
Mr Naidu said large sections of the Kings and Queens roads were closed to all traffic at 9.30am yesterday morning.
"The following roads - Queens Rd at Sigatoka Village, Navo and Navutu, Kings Rd at Matawalu, Vatamai, Tavualevu, Rakiraki flats and Wailailai flats - are under more than one metre of water and closed to all traffic."
He said landslides closed Valley and Ciri roads in Sigatoka. Motorists are urged not to make unnecessary trips and police have restricted movement on the Queens Rd from Korolevu to Lautoka.
