THE worst bushfire conditions in many years will hit NSW tomorrow as temperatures across the state soar to near-record levels.The mercury is expected to skyrocket in many parts of the state as a heatwave pushes super hot air from inland Australia into NSW.
In the state's far west the temperature in some towns is predicted to hit 45C, while in Sydney the mercury is forecast to climb to 43C - making it the third highest temperature on record.
NSW Rural Fire Service Commissioner Shane Fitzsimmons said tomorrow's "awful conditions" meant bushfires would spark very easily.
"We're going to experience conditions like we haven't seen for many many years," he told the Seven Network.
"Given we've got this plentiful supply of fuel, particularly grassland fuel, across much of the very bad weather areas fires will start very easily and spread very quickly."
He said NSW was now "well and truly in the bushfire danger period".
"We've got awful conditions coming our way, and people need to be prepared," Comm Fitzsimmons said.
The extreme bushfire conditions will impact many parts of the state, including the Riverina, western ranges, Illawarra and coastal areas.
Westerly winds would add to danger, with gusts of between 60-80k/h expected in many areas.
Total fire bans remain in place today in the southern and northern Riverina, the RFS advises on its website.
