NSW firies launching major hazard reduction burns operation ahead of hot, dry winter - 9News

The hazard reduction burns are expected to cast a pall of smoke over Sydney, as heavy fog clears from this morning.

The burns are intended to ward off what is forecast to be a potentially bad fire season when the weather warms up.

The devastating bushfires of 2019 and 2020 were followed by the unusually rainy La Nina years, which has allowed a quick regrowth.

A dry winter will add to the fire risk in the state.

Currently, the RFS has burned less a quarter of its target for this time of the year.

The city has been rain free since May 20 and will likely remain that way until Sunday.

"There were spatters of rain on Thursday in some suburbs but nothing that was heavy enough to register at the Observatory Hill weather station where official records for Sydney are kept," Weatherzone said.

"That means it has now exceeded the 13-day streak from June 6 to 19, 2022."

Warmer-than-usual daytime temperatures are expected in almost every state from June to August, a far cry from the cooler, wetter conditions brought about by La Nina's in the previous three years.

Temperatures will drop a little bit at nightfall, with western New South Wales, southern parts of Queensland, eastern South Australia and southern areas of the Northern Territory all expected to experience cooler nights in winter.

Rain levels are also expected to ease this winter, with a high chance of below-average rainfall, especially across southern NSW.

"While the models show it's very likely that the tropical Pacific Ocean temperatures will reach El Niño levels during winter, a shift in the tropical atmosphere is also needed for us to declare an El Niño event," the BoM said.

The warm and dry conditions could lead to increased bushfire risk for a large part of the Northern Territory, pockets of NSW and north-western South Australia.
