Higher chance of more tropical cyclones, early monsoon amid negative Indian Ocean Dipole and possible La Nina

Northern Australia’s wet season is likely to arrive earlier this year, according to the Bureau of Meteorology (BOM), bringing with it a higher likelihood of more tropical cyclones off coasts.

Much of south-eastern Australia has been impacted by record-breaking floods as a result of La Nina, while the north of the continent recorded decent rainfall totals during the last wet season.

Now the weather bureau has officially declared another climatic phenomenon — known as the negative Indian Ocean Dipole — that’s expected to add to recent unrelenting rain on the east coast.

The weather system is also predicted to lead to wetter weather across the Top End of the Northern Territory and Far North Queensland. However, parts of northern Western Australia are likely to remain somewhat drier.

Northern Australia’s wet season typically runs from December to April, following a build up of hot and humid conditions from October.
