Firefighters are still tackling bushfires in the towns of Ensay and Timbarra, about 340 kilometres northeast of Melbourne.

Fire crews are assessing the spread of the fire and developing strategies to tie it into existing containment lines.

Aircraft are also monitoring the areas, as well as the nearby towns of Buchan, Buchan South, Sunny Point, who have also had their fire danger downgraded to advice level.

A watch-and-act warning was in place early Tuesday morning after a blaze began during Monday's extreme heat in Timbarra.

Residents were also advised to stay indoors as a precaution.

Another 10 bushfires are burning across the state, covering about 47,000 hectares, according to the Country Fire Authority.

"The fires mainly cover remote forest regions, where extreme dryness and rough terrain is making it difficult for firefighters to reach," a spokeswoman told AAP.

Northern and northeast Victoria remains at very high bushfire risk despite the cool change overnight.
