Temperatures have halved in Victoria overnight but firefighters are still battling several fires across the state which are burning out of control.
Melbourne is headed for a top of 21C on Saturday just a day after being belted with scorching heat, with some northern centres reaching 46C on Friday before the cool change swept through.
The milder conditions are expected to bring relief to firefighters battling two major blazes to the north and east of Melbourne on Saturday morning.
A watch and act alert is in place for residents near Rosedale, in the state’s east, which has been burning overnight.
Emergency services warned people in Kilmany, Fulham and Wurruk to monitor the dangerous conditions as the fire burns in a north-easterly direction towards them.
Meanwhile, a second watch and act is in place for a grassfire burning near Ancona, Merton and Strathbogie.
A wind change helped firefighters slow the spread of the fire overnight, but nearby residents have been warned to stay on high alert through the morning.
Victoria Police told AAP it was investigating the cause of the Rosedale fire.
Emergency Services Minister Lisa Neville warned on Friday that the “danger period is not over” with scope for more blazes.
