Premium Content Subscriber only As rain continues to fall across the Northern Rivers and thunderstorms are predicted, the Bureau of Meteorology has issued an updated flood watch with early advice of possible flooding within the Richmond, Wilsons and Orara rivers. At 10:11am today, the BOM warned of moderate rainfall associated with a weakening low pressure trough moving through northeast NSW until Thursday evening. The BOM said the flood watch meant people living or working along rivers and streams must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop. "This has the potential to cause minor riverine flooding across the Orara River and Richmond Wilsons catchments on Thursday," the BOM said.
