Heavy rain experienced in most parts of Fiji since the weekend is due to a trough of low pressure situated at the South Eastern parts of the group.

Meteorology Director Ravin Kumar told FBC news, this adverse weather condition is expected to lie around the country until Friday.

He says the downpour will continue over the next few days with occasional showers and isolated thunderstorms expected at most places around the country.

Kumar adds flooding is expected not only due to heavy rain but drain blockages too.

The director has advised people to stay indoors during thunderstorms and stay away from drains and creeks during flooding.
