THE Bureau of Meteorology has declared a negative Indian Ocean Dipole event is underway, which will cause a spike in temperatures across Northern Australia during the rest of winter and spring.
A negative IOD typically increases the chance of winter and spring rainfall over much of southern and eastern Australia, while northern states and territories will see temperatures skyrocket.
Brought about by ongoing changes in the difference between sea surface temperatures of the tropical western and eastern Indian Ocean, the climate phenomenon influences rainfall patterns around the Indian Ocean.
Bureau of Meteorology meteorologist Mosese Raico said “negative IODs tend to be less frequent and not as strong as positive IOD events,” however, forecasts could become more severe if a La Niña event occurs.
“There are several indications that a La Niña event could occur,” he said.
“If that did happen in conjunction with the negative IOD it would have an impact on the NT.”
Mr Raico said the NT could see the rain and monsoon season moved forward and the “total number of tropical cyclones increase across all tropical waters in Australia” if a La Niña event began.
Bureau of Meteorology head of long-range forecasting Dr Andrew Watkins said the Bureau’s 3-month climate outlook is for above average rainfall for much of Australia, particularly for the central and eastern states.
“With wet soils, high rivers and full dams, and the outlook for above average rainfall, elevated flood risk remains for eastern Australia,” he said.
Communities are encouraged to keep up to date with the latest Bureau forecasts and warnings through the Bureau’s website and BOM Weather app and follow the advice of emergency services.
