Spot fires are burning kilometres ahead of a fire front in Victoria's east as firefighters warn locals that weather conditions could rapidly alter fire behaviour.
Residents in East Gippsland's Tambo Crossing area have been told it's too late to leave and to immediately shelter indoors.
"The bushfire at Marthavale-Barmouth Spur is out of control ... and is impacting private property in Tambo Crossing," the warning says.
The Great Alpine Road between Bruthen and Ensay is closed.
Ensay is also under an emergency warning, advising residents to take shelter indoors.
Ensay is also under an emergency warning, advising residents to take shelter indoors.
The Great Alpine Road to the north of Ensay remains open and people leaving the area have been told to head north to Omeo where a relief centre has been opened.
A watch and act notice has been issued for Brookville, to the northeast.
"Spot fires are occurring several kilometres ahead of the fire front," the notice warns.
"Weather conditions influencing this fire can change rapidly. Remain vigilant and aware of what is happening in your area."
Two separate blazes are burning in the area and firefighters from more than 70 trucks are battling the twin fires which have burned nearly 60,000 hectares of mountainous bush.
A cool change swept across Victoria overnight bringing relief in temperatures but increased fire danger with dry lightning.
On top of the 110 fires burning on Friday, another 33 started after midnight and 16 of those remain out of control.
Evacuation orders issued on Friday for Lexton, near Ballarat, have been lifted but those who left have been told "do not return".
Fresh warnings on Saturday advise that leaving is the safest option for those in the path of the blaze.
"Firefighters have been able to slow the spread of fire for now, but the situation can change at any time," it says.
A similar warning for residents in Bamganie, Shelford, Teesdale - about 40 kilometres northwest of Geelong - was downgraded to an advice warning.
Alleged firebug charged
A Melbourne man is set to face court accused of deliberately setting grassfires in the city's northern suburbs.
The 47-year-old was arrested on Saturday morning over three blazes in Craigieburn and Roxburgh Park in the early hours, as well as a series of fires dating back to October.
Police say fire crews extinguished the blazes before they could damage properties.
He's expected to face the Melbourne Magistrates Court on Saturday on 11 charges, including intentionally causing a bushfire and criminal damage by fire.
