Victoria – from fires one day to flooding the next

Victoria and Melbourne specifically are often known for having four seasons in a day, but how about two opposite weather events in 24 hours?

That’s what’s occurring across eastern Victoria today.

Firefighters battled emergency warning fires on Monday and Tuesday across the East Gippsland region, with over 12300 acres burnt in the area, and over 220 bush and grassfires across Victoria since Saturday. Fast forward 24 hours and those same fires have nearly been extinguished by heavy rainfalls.

In the 24-hours to 9 am Wednesday, widespread falls of 70-150mm have been recorded across parts of central and eastern Victoria with record-breaking October rainfall for numerous sites across the state.

Heavy falls haven’t only helped in extinguishing fires across the eastern half of the state - they have alleviated the fire weather threat after several months of very dry conditions.

Numerous rivers are beginning to flood, with the Macalister River at Licola entering major flooding this morning. The rain will continue to tumble on Wednesday, with further falls of 30-80mm possible across the eastern half of the state, exacerbating ongoing flooding for rivers and creeks.
