As it stands, there is a mild flood warning for the Lachlan River and minor to moderate warnings for the Culgoa, Bokhara and Darling rivers.
After recording the start of the wettest year on record, Sydney recorded the driest June since 2005 after the end of La Nina and the start of a negative southern ring mode.
The Meteorological Office declared the end of La Nina on June 21, but warned that the pattern has a 50% chance of resurfacing for the third time. This phenomenon is known as the “triple fall” and is dictated by the southern oscillation perspective of El Nino.
“Most models indicate neutral [El Nino – southern oscillation] will persist through the winter “.
However, four of the seven models indicate that La Nina could return in the spring and the rest will remain ENSO neutral until the end of 2022, ”the prospect says.
