Although the rain has subsided today, authorities have warned that the risk of flooding will continue for the next few days.

“The system that brought intense thunderstorms last night is now hanging off the Gold Coast. We could still see a bit more rainfall in the morning,” said the bureau’s senior forecaster Dean Narramore.

“We expect more widespread showers across the NSW coast and south-east Queensland today and again tomorrow before finally clearing on Sunday.”

“Unfortunately, another weather phenomenon will move into eastern Australia in the middle of next week.”

There are currently nearly two dozen flood warnings in place for swollen watersheds across the state.

“We are facing challenges on a number of fronts with prolonged flooding in western and north-western NSW, renewed river rises in the Central West and southern NSW,” he said.

“Communities in the Northern Rivers, Mid-North Coast and North Coast, who have been weary of flooding in recent months, are facing a couple of days of worsening weather conditions.

“We’re at the start of a very long season that we’re looking forward to, this is the third La Nina in a row and as we’ve seen all year our watersheds and landscapes are very saturated.

“It increases the risk of flash floods and very fast water and catching people off guard.”
