"Large parts of Australia are extremely dry as we head into the warmer months, especially in the east where some areas have seen very little now for three years," he said.

"We expect the warm and dry trends to continue for the remainder of the year.

Mid Lachlan Valley RFS district manager Superintendent Ken Neville said bushland areas across the zone were of greatest concern to firefighters.

"There's less moisture so trees will burn a lot easier," he said.

"With the drought and lack of rain we've had everything is just tinder dry."

Supt Neville said storm season, which runs from October to March, also increases the risk of bushfires.

"Our biggest threat now that we're in storm season is lightning strikes, they're responsible for a number of fires each year," he said.

"It's something that's certainly happened in Goobang National Park, the Weddin Mountains and the Manna Mountains.

"If a fire starts it'll burn quickly."

So far this year Parkes has received well below average rainfall with just 198.8 millimetres recorded to the end of September. The long term average is 446.1mm.

Permits are required for all burn offs on rural properties during the bushfire danger period and these can be obtained by contacting your local fire control centre.

People are also urged to be careful when any equipment that creates sparks on hot and windy day.
