Flood warnings issued as a week of rain hits east coast

New South Wales faces another possible round of floods this week as a "long-lived" rain event continues.

The eastern coast from the Illawarra to the Hunter saw falls of 20mm to 30mm yesterday, with totals rising to a high of 65mm at Point Perpendicular at the northern entrance of Jervis Bay.

Increasing rain is also expected today, moving inland over the Central West and Northern Tablelands this afternoon.

The system is also expected to bring rain to south-east Queensland, including the Darling Downs.

Helen Reid from the Bureau of Meteorology said while the daily totals may be modest, the "prolonged nature" of the weather system would see "quite large" accumulations by the end of the week.

"The rain this week is concerning for NSW because of how wet it's been in recent weeks," she said.

The ground is too saturated to absorb the rain in most affected areas, with much of eastern NSW having already had three to four times its average August rainfall this month.

Flood watch warnings are in place, and anybody living on or near a waterway in the rain-affected regions is urged to keep an eye on updates.

The rain is expected to be heaviest on Wednesday and Thursday, with 24-hour totals on the beleaguered NSW Mid North Coast a chance to top 100mm, Reid said.

The rain event is set to ease on Friday, with the system pulling back toward the coast.

Skies are expected to be fully clear by Saturday, Reid said.
