It is likely to be wetter than usual along Australia’s east coast this summer, according to the Bureau of Meteorology’s long-range forecast.

Following Victoria’s wettest spring on record, the BOM warns the state is yet to be disencumbered from potential flooding, with significant rainfall posing the potential to lead to widespread flooding where rivers are already high, dams are full, and catchments are wet.

Above-average rainfall also increases the risk of landslides and tree falls in areas of steep terrain and very wet soils.

The long-range forecast also predicts cooler days are likely for most of New South Wales, southern Queensland, and Victoria.

This summer there is also an increased risk of:

-Prolonged heatwaves with higher humidity in southern areas;

-An above-average number of tropical cyclones and tropical lows;

-Coastal flooding in the east and north with unusually high tides forecast around January 23 and February 20;

-Marine heatwaves with warmer than average waters around Australia, and;

-Thunderstorm asthma events in the south while pollen counts are high in early summer.

A range of climate drivers around Australia are contributing to the wet outlook in the east, including a La Niña in the Pacific Ocean, a positive Southern Annular Mode and warmer ocean waters around Australia.

The negative Indian Ocean Dipole event is weakening and will likely come to an end by early summer, while the La Niña in the Pacific Ocean may start to ease in early 2023.

The BOM issues warnings about floods, heatwaves, fire weather, tropical cyclones, tsunamis, severe weather and severe thunderstorms.

It is important to know your weather and know your risk so you’re ready to act and stay safe.
