Flood Watch Number: 1

MINOR FLOODING POSSIBLE IN THE MANNING, MYALL, PATERSON WILLIAMS AND HUNTER CATCHMENTS FROM MONDAY

A trough is expected to cross NSW during the weekend, deepening offshore into a low pressure system by Monday. This low is expected to bring widespread rainfall about central parts of the NSW coast and may cause minor flooding in several catchments between the Manning and Hunter from Monday.

Catchments in the Flood Watch area are relatively wet.

There is some degree of uncertainty over the exact location and timing of the heaviest falls. Localised river level rises, and flash flooding are likely within the areas of heaviest rainfall.

This weather system has the potential to cause minor flooding in the Flood Watch area from Monday. Flood Classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service.

Catchments likely to be affected include:

Manning and Gloucester Rivers minor flooding

Myall River minor flooding

Goulburn and Upper Hunter Rivers minor flooding

Wollombi Brook and Lower Hunter River minor flooding

Newcastle Area

Paterson and Williams Rivers minor flooding

Flood warnings current in the following catchments: Warrego and Darling

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.

Severe Weather Warnings will be issued or updated if very heavy rain is forecast or observed.
