The Rural Fire Service (RFS) continues to implement containment strategies for multiple fires burning along the South Coast.

Although the rain is helpful, an RFS spokeswoman said a lot is needed to make a significant impact on the firegrounds. She said rain can make access difficult for fire trucks.

"Smaller amounts of rain can hamper access as tracks and trails become slippery," the spokeswoman said.

She warned the community and anyone travelling on dirt or non-sealed roads to take extra care.

The spokeswoman said more benign conditions are expected from Monday through to Thursday and deteriorating conditions on Friday.

"At the moment, indications from the bureau are not as big as the previous bad weather," she said.

She said a more accurate prediction of Friday's weather would be assessed tomorrow.

Clyde Mountain Fire: Overnight, the fire was still active in parts of the Deua Valley and through to Waldrons Swamp area, north of Moruya, the RFS spokeswoman says.

"There's some active fire at Percy Davis Drive and George Bass Drive where we are back burning, consolidating and mopping up," the spokeswoman said.

"We're property protecting in the Deua.

"North Mogendoura and Waldrons Swamp towards Broulee Road - there's some back burning, otherwise things are calm."

She said some residents have not yet been able to return to parts of the Deua Valley and the top of Larrys Mountain Road.

Coondella Fire: The fire is still moving in the area, the spokeswoman said: "It has not grown significantly over the past couple of days."

Badja Forest Fire: From Moruya to Bodalla and Narooma to Bermagui - the fire hasn't impacted into communities, the RFS spokeswoman says.

"We have allowed people to return home but they need to monitor the situation," she said.

"We continue to work with the community and have a containment strategy in place.

"We ask the community who have returned home to continue preparing their property."
