The Bureau of Meteorology has issued a flood watch warning for the Macleay Valley for minor flooding. 

According to the bureau, a low pressure trough will deepen off the northern New South Wales coast on Wednesday and persist into the weekend, with the potential for significant rainfall totals to build up in the northeast by the end of the week.

This rainfall has the potential to cause flooding to develop in the following river valleys from Wednesday onwards:

1. Richmond-Wilsons - minor flooding

2. Orara - minor flooding

3. Coffs Coast - minor flooding

4. Bellinger - minor to moderate flooding

5. Nambucca - minor to moderate flooding

6. Macleay - minor flooding

7. Hastings - minor to moderate flooding

This flood watch means that 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.

Flood warnings will be issued if the 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 70 per cent of Flood Watches are followed by flooding.
