Weatherzone meteorologist Yoska Hernandez said the heatwave was driven by a slow-moving weather pattern over southern Australia.

“With minimal change expected in the overall circulation, hot air continues to spread across south-eastern parts of the country, allowing the extreme heat to persist,” Hernandez said.

As temperatures rise across Australia, meteorologists will also keep their eyes on a tropical system off the coast.”At the same time, a tropical low in the eastern Indian Ocean is forecast to strengthen, with a possible tropical cyclone approaching the Kimberley coast late this week.

“This tropical system is influencing large-scale atmospheric circulation, helping sustain upper-level ridging and reinforcing the pattern that is keeping extreme heat entrenched across south-eastern Australia.”
