The NSW State Emergency Service is urging Sydneysiders to prepare for the “most intense” storm season in four years.

The Bureau of Meteorology’s severe weather outlook for this summer predicts an increased risk of heatwaves, bushfires and potentially damaging storms.

NSW SES Deputy Commissioner Rob McNeill told the Sydney Morning Herald that he expects this season’s storms to be severe, with “violent weather behaviour” predicted between October and March.

“We’re likely to see storms that bring large hailstones, tornadoes, heavy rain, localised flash flooding and damaging winds,” Mr McNeill told the publication.

“What is changing is the storm season corresponds with the bushfire season, which can give us some quite unusual situations like [in September] we had storms running through Sydney and also had bushfires impacting out in the Lithgow area.”

In preparation for the wild weather, residents are being urged to prepare, with NRMA Insurance manager Alex Mazzoni telling the Herald that “prevention is key”.

“Trim your branches, clear your gutters and secure loose items in your garden on your balcony. Severe weather can strike at any time, so these little actions can make a big difference,” he said.
