Flood-prone NSW communities are being warned to brace for a "dangerous" 72 hours, as widespread rainfall and thunderstorms are set to wash over the state.
The State Emergency Service has issued warnings that towns could face renewed flooding to levels experienced over the past few weeks.
"This rainfall is combining with already saturated catchments and full river systems which will lead to more flooding across many parts of the state," NSW SES Commissioner Carlene York said in a statement on Friday.
