MINOR TO MAJOR FLOODING POSSIBLE IN THE HAWKESBURY NEPEAN RIVER FROM LATE FRIDAY

MINOR TO MODERATE FLOODING POSSIBLE ACROSS PARTS OF NEW SOUTH WALES COAST AND RANGES FROM LATE THURSDAY

A weak trough lies on the far north coast between Thursday and Friday. An inland trough is forecast to deepen and potentially develop into a low pressure system on Friday. The system is expected to bring rain to much of the state in the coming few days with locally heavy falls, particular in the east. There is still uncertainty associated with the location and intensity of the heaviest falls. The inland low and coastal trough are expected to move further south through Saturday with the rain easing over New South Wales. This rainfall has the potential to cause minor to moderate flooding along parts of the New South Wales coast and ranges from late Thursday. Minor to Major flooding is also possible along the Hawkesbury Nepean River from late Friday.

Catchments are relatively wet in the north and average to dry around Sydney and the South Coast.

The weather system may cause flooding for the catchments listed from Friday into the weekend. Flood Classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service.
