Fresh Victorian bushfire warnings issued

Communities near Melbourne have been issued fresh bushfire warnings and told to prepare to flee, as more hot, windy weather is forecast.

Fire authorities on Sunday said severe fire weather was predicted for Monday and people in the Warburton/Yarra Valley area and near Enoch Point should be prepared.

Country Fire Authority (CFA) State Duty Officer Neil Bumpstead said in a statement that people wishing to leave should go either Sunday evening or Monday morning.

"We cannot stress enough that with limited road access in the Warburton Valley, traffic may become congested," Mr Bumpstead said.

"Being on the roads is dangerous during a fire threat," he said.

At least 209 people are known to have died in the Victorian bushfires, which have been raging since Black Saturday on February 7.

Department of Sustainability and Environment (DSE) spokesman James Todd said about 3,500 firefighters from across various agencies battled ongoing fires on Sunday.

Four major fires were still burning out of control, the Kilmore-Murrindindi Complex North, and the Kilmore-Murrindindi Complex South, the Bunyip Ridge fire and one at Wilson's Promontory.

"The Murrindindi Complex North ... has unfortunately broken containment lines and that is posing some immediate risk to some small settlements up there, Enoch Point being one," said Mr Todd.

"DSE is pulling its vehicles and machinery out of that area now and falling back to some asset protection back around Eildon and Jamieson.

"For the Murrindindi complex in the south, the fire is east of Melbourne and has been burning into the water catchments.

"There has been some good work done on control lines, but with the weather looking a bit nasty (on Monday) in terms of increasing northwesterlies and a southwesterly change there is a significant risk attached to that fire."

Terry Ryan from the Bureau of Meteorology said Melbourne could expect a top temperature on Monday of 34 degrees celsius, but other parts of the state would reach a maximum of 40C.

"It will be the worst day for two weeks, since that Saturday," Mr Ryan said.

He said a gusty change was due to hit Melbourne about 3pm (AEDT) with cooler weather forecast until Friday, when the mercury is expected to peak at 35C in Melbourne.
