ISOLATED storms have lashed areas of the Colac district, causing flash flooding and miniature tornadoes.
But Colac itself remained unscathed, missing storms that hit just kilometres from the city.
Alvie received a 30-millimetre deluge in 15 minutes, a storm that included at least three mini tornadoes touching down on Thursday afternoon.
An Alvie resident who witnessed one of the tornadoes said the weather conditions were as bad as she had seen since she had lived in the area.
Bureau of Meteorology duty forecaster Chris Godfred said tornadoes were a feature of concentrated thunderstorm cells and were also the result of differing wind speeds and directions in the atmosphere.
“I think it’s something that’s not very common but it’s certainly not unique or out of the ordinary. It just relies on the atmosphere being in the right configuration,” he said.
Meanwhile, Warncoort received 70mm of rain in an hour on Thursday afternoon causing flash flooding and water over the Princes Highway.
Neighbouring Birregurra received only 13mm and Colac, 4mm, in the 24 hours to 9am Friday.
Colac Police attended the flash flood at Warncoort and directed traffic until VicRoads workers arrived to erect warning signs.
Colac State Emergency Services received no call-outs due to the storms.
Showers persisted on the weekend, with Colac’s Mount Gellibrand weather station recording 23mm from 9am Friday to 9am Sunday.
