Department of Sustainability and Environment Midlands fire district duty officer Mike Forsyth yesterday said firefighters were called to eight fires in bush near Greendale and Daylesford on Tuesday afternoon and a further two at Mt Cole and Mt Lonarch, near Beaufort, later in the evening as the storm progressed.

Yesterday, firefighters fought minor blazes in Ballarat, Beaufort, Chute and Morrisons.

Mr Forsyth said with more storms expected in the region through last night and today, more fires were expected, but the rain accompanying most of the lightning strikes was aiding firefighters.

"Most of them have only burnt about 100sqm. Usually a single tree is hit by the strike and then the fine fuel on the ground doesn't carry or ignite too far because it's usually moist with the rain," he said.

"A whole lot of storm activity pretty much started again from 11am (yesterday), so we are expecting there will be more strikes we need to attend, but we have access to regular lightning updates from the Bureau of Meteorology

and two spotter aircraft on standby to assist us."

Mr Forsyth said a lack of wind was also aiding firefighters to contain blazes quickly.

He said approximately 12 firefighters remained at Mt Cole yesterday to black out, as it had been the only blaze in the region where rain did not accompany the lightning strike.

He said the DSE and CFA in the Midlands district - which stretches from outer Melbourne to beyond Beaufort - were well prepared to handle any blazes.

"We have four-wheel-drive units and tankers, and the CFA has an armada of tankers available," he said.

"We also have what we call first-attack dozers strategically placed throughout the region.

"Overall we are pretty well prepared.

Mr Forsyth urged the public to be vigilant and report smoke sightings to emergency services.
