Firefighters are working to stop two major bushfires from joining as they defend eight homes in the line of fire in Victoria's west.
The two fires burning in the southern part of the Grampians ranges are each about 800 hectares in size and they are now a kilometre apart, a CFA State Control Centre spokesman said.
"Crews are trying to put in containment lines to separate them," the spokesman said today.
"That's the focus of this morning and overnight."
The fire, which is 30km north of Dunkeld, is moving slowly and is expected to impact the Mirranatwa area by 10am (local time).
The out of control blaze is moving southwards towards eight properties, but has slowed a little, the spokesman said.
There are about 50 properties in the valley area and overnight the fire moved to flatter ground, helping firefighting efforts.
The CFA issued an emergency warning earlier today but downgraded its warning to Mirranatwa to a Watch and Act.
