Source: Bureau of Meteorology

Issued at 1:26 pm EST on Thursday 30 June 2022 Flood Watch Number: 1

MINOR TO POSSIBLE MAJOR FLOODING FOR PARTS OF THE MID NORTH COAST TO THE ILLAWARRA

The BOM has just released Flood Watch 1, as rain is forecast from tomorrow, and it includes potential minor to major flooding for some of our rivers and catchments.

This is a Flood Watch not a Flood Alert.

“The weather system is expected to cause flooding for the catchments listed from later Saturday” – BOM.

Hawkesbury and Lower Nepean Rivers minor to major flooding

Upper Nepean River minor to major flooding

Upper Coxs River

Colo River minor to major flooding

Macdonald River

Heavy rainfall is forecast to develop through central parts of the NSW coast from the Illawarra to southern parts of the Mid North Coast during Saturday.

The heavy rain may cause minor to moderate flooding and is expected to intensify further in the new week with major flooding possible.

Whilst heavy rainfall is expected for several days from Saturday through to Tuesday it is difficult to predict with precision the timing and location of the heaviest rainfall and flood impacts, as the trough system expected to produce the heavy rainfall has not yet formed.

Water storages are near capacity.

The weather system is expected to cause flooding for the catchments listed from later Saturday. Flood Classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service.
