Authorities are preparing for what should be the warmest day so far this fire season.
Temperatures are expected to top 40 degrees across north central Victoria.
The Country Fire Authority's Justin Dally says local crews are on alert.
"The wind is the main concern at the moment," he said.
"If the winds do get up a bit and start blowing, that creates a big problem with how fast fires can develop and then threaten our communities."
Meanwhile, officials say the closure of a fire spotting tower in central Victoria will not upset their operations today.
The Department of Sustainability and Environment (DSE) has confirmed the One Tree Hill tower near Bendigo will not be operational until tomorrow because of renovations.
However, the DSE says other towers in the region will be in use and aircraft are available.
