Authorities have warned rain will only provide temporary relief as more than 40 fires continue to burn across Queensland.

The wet weather has allowed crews across the Southern Downs region to contain some blazes and strengthen containment lines on others after a marathon two weeks fighting more than 1000 bushfires.

This morning fire authorities told people in Carnarvon Gorge, Buckland, Consuelo and Rawan to prepare to leave as conditions could worsen quickly with multiple fires burning in the Carnarvon National Park and Bandana State Forest.

Many other fires have been downgraded to advice level but residents have been told to stay up to date with the latest information from Queensland Fire and Emergency Services (QFES) and local authorities.

"Fire grounds are still a dangerous place to be," Rural Fire Service Chief Superintendent Tony Johnstone said.

"The storms that we're seeing today have allowed some fires to be quelled but potential of lightning strikes may see others occur over the next few days."

The work of local crews is being bolstered by 130 firefighters from Victoria as well as crews from New Zealand.

"I'd like to acknowledge the incredible work that's been done on the ground from the rural volunteers to our Fire and Rescue colleagues to the local governments to those doing resilience and recovery to the community members," Johnstone said.

"It's been a massive effort by everyone and this is the strength of Queenslanders."

Authorities said 60 houses, 50 sheds and 11 caravans have been lost so far after more than 600 damage assessments were carried out.

"Sadly some of our own people have been affected by these property losses," Johnstone said.

Fire bans remain in parts of the state due to excessively dry conditions.

As smoke is expected to remain across the region in the coming days, people are being asked to take the necessary health precautions.

The fires have proven to be unpredicted over the last few days, with one in particular flaring up on the New England Highway shortly after the road had re-opened on Thursday.

The last two weeks have been nerve-wracking for residents, some of which have been forced to evacuate their homes or remain on alert for evacuation orders.

Wyberba Anthony Rice was among the residents told to prepare to leave for his home overnight.

Fire authorities have since downgraded the warning to watch and act.

"We saw a wall of fire coming up over that ridge there," Rice told 9News.

"That was pretty unsettling."

A low-pressure trough is set to bring rain and thunderstorms daily to eastern Australia from today until potentially late next week.

Projected falls of up to 20mm to 40mm could happen over southern Queensland and northern NSW.

Rural Fire Service regional manager Wayne Waltisbuhl said firefighters have battled bushfires for months and he believes the worst of it "is not over yet".

"We've not seen fire behaviour like this before," Waltisbuhl said.

"Complacency is not something we want to talk about right now.

"The other day our deputy commissioner said we're in this for a marathon and there's a couple of sprints in between.

"Well, we're just going for a fast walk now while this bit of rain is around and we'll see what happens."

Waltisbuhl said the Dalveen area in particular will need at least 50 mm of rain to get the fires "well under control".
