Flood Watch Number: 1
MINOR FLOODING POSSIBLE IN PARTS OF THE HAWKESBURY-NEPEAN FROM OVERNIGHT FRIDAY INTO SATURDAY
A trough near the NSW coast is expected to deepen during Friday, bringing enhanced rainfall to the Central Coast, including the Hawkesbury Nepean Valley. This may cause minor flooding in parts of the Hawkesbury and Nepean catchments from overnight Friday into Saturday.
Catchments across the Hawkesbury Nepean Valley are around average wetness for this time of year, but wetting up slightly following rainfall over the last week.
Widespread moderate rainfall totals are likely about the upper catchments during Friday afternoon and evening, with localised heavy falls possible. Rainfall during Saturday morning may extend more broadly across the Hawkesbury Nepean Valley, with widespread moderate rainfall likely and local heavy falls possible.
The weather system may cause minor flooding in parts of the catchments listed from overnight Friday into Saturday. Flood Classes (minor, moderate, major) are only defined for catchments where the Bureau provides a flood warning service.
Catchments likely to be affected include:
Upper Nepean River
Hawkesbury and Lower Nepean Rivers
Upper Coxs River
Colo River
Macdonald River
