A Severe Weather Warning for damaging wind and heavy rain is also current for the Northern Rivers, Mid North Coast and Northern Tablelands weather forecast districts.

This warning will be updated regularly as the event unfolds.

This Flood Watch means that people living or working along rivers and creeks must monitor the latest weather forecasts and warnings and be ready to move to higher ground should flooding develop.

Flood Warnings will be issued if Minor Flood Level is expected to be exceeded at key sites along the main rivers for which the Bureau of Meteorology provides a flood warning service.

Across NSW about 75% of Flood Watches are followed by flooding within the catchment.
