Flood Watch Number: 2
MINOR FLOODING WITH ISOLATED MODERATE FLOODING POSSIBLE FOR PARTS OF THE HAWKESBURY NEPEAN VALLEY AND SOUTH COAST FROM LATE SATURDAY
Persistent coastal showers are forecast along much of the east coast throughout Saturday and into Sunday as an upper trough brings widespread rain and thunderstorms across much of New South Wales. The heaviest rainfall is expected along the South Coast. This rainfall may cause minor flooding with isolated moderate flooding in parts of the Hawkesbury Nepean Valley, St Georges Basin, Bega and Moruya catchments.
Catchment are relatively wet along much of the NSW coast due to rainfall and isolated flooding in recent weeks.
The weather system may cause flooding for the catchments listed from late 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:
Hawkesbury and Lower Nepean Rivers
Upper Coxs River
Colo River
St Georges Basin
Clyde River
Moruya and Deua Rivers
Bega River

ENSO status: Inactive. IOD status: Neutral, becoming positive. SAM status: Neutral, favouring positive in winter. The El Niño Southern Oscillation (ENSO) is in an inactive phase. Ocean cooling is occurring in the eastern Pacific, with 3 out of 7 global models forecasting a La Niña to develop in 2024. Warmer than normal waters are situated in the Coral Sea, providing moisture and humidity to the east coast. The atmosphere continues to be firmly neutral after weakening early in the year. A neutral ENSO typically has no significant impact on Australian rainfall during winter. The Indian Ocean Dipole (IOD) is in a neutral phase. Ocean temperatures are at record levels in the western Indian Ocean, and the IOD index is spiking in response. Persistent southeasterly winds have set in over the eastern Indian Ocean, signalling that the atmosphere is starting to respond to the ocean patterns. A burst of tropical activity expected in mid-May could make-or-break this event, as tropical activity in certainlocations could either strengthen or hinder the development of a positive IOD. If this tropical activity is favourable for a positive IOD, significant upwelling near Indonesia may occur as soon as late-May. A positive IOD reduces the number of northwest cloudbands that cross Australia during winter and spring, reducing rainfall across central and southeastern parts of Australia. The Southern Annular Mode (SAM) is neutral but is expected to favour a positive phase during winter. A positive SAM increases easterly winds, increasing rainfall and thunderstorm activity in the east, while cooling temperatures. A positive SAM reduces cold fronts and rainfall over southern Australia, particularly for southwest WA. Rainfall outlooks are showing slightly below average rainfall over winter for WA, and the southwest coasts of SA, Vic and Tas. Conversely, above average rainfall is expected for eastern parts of Qld and NSW, and potentially eastern Tas.
