Fire danger conditions in Victoria today are likely to be dynamic, with strong winds forecast for the North Central district of the state.

The Country Fire Authority has declared a total fire ban in the Northern Country, North Central, Central - including Melbourne and Geelong- North East, East Gippsland and West and South Gippsland districts.

With soaring temperatures across the state accompanied by extremely strong winds, particularly in the Alpine area, firefighters are focused on two main fires - the Harrietville-Feathertop and the Aberfeldy-Donnellys blazes.

A CFA spokesperson said that despite fairly low fire activity overnight, the Harrietville-Feathertop fire had breached containment lines on the western and southern side of the Great Alpine Road, with the perimeter now reaching close to a 100 kilometres.

However, it has not impacted on any additional communities.

A Bureau of Meteorology spokesperson said that "there is a lot of work to be done on both fires, but the main concern for today is the Feathertop fire due to the wind conditions.

"The 9am winds out there are already about 35km/h, soon to be about 50," he said earlier.

Soaring temperatures will also impact today's fire activity, with Gippsland already experiencing temperatures into the low 30s.

CFA has confirmed that there are 42 aircraft operating or strategically placed around the state to fight fires, and that "Victoria is well prepared, well resources and ready to jump up when a fire crops up".
