Melbourne's Olympic Park weather station recorded 47.8mm of rain from 9am on Thursday, the city's highest daily total since April 2024. Emergency crews answered more than 200 calls for help as the storm moved through.
The Deluge
The numbers came quickly. Up to 25mm fell in one hour Thursday afternoon, roughly half the day's total in about sixty minutes. Flash flooding hit parts of Melbourne. Storms and flash flooding also struck other parts of Victoria.
At about 3pm, the city went dark as the weather system rolled across it. For a few hours, a major capital looked more like dusk than mid-afternoon.
David Crock, a senior meteorologist with the Bureau of Meteorology, confirmed the record. The rainfall total, he said, was the city's highest daily figure since April 2024, two years elapsed by today's date. His next remark was blunt. "There is much more to come," he said.
Emergency Response
The State Emergency Service handled the load. More than 200 calls for help came in, including six water rescues. Those figures show who gets sent when conditions turn dangerous, and how quickly demand can build when a storm cell stalls over a city of this size.
Six water rescues in one afternoon means six situations where people or property were in real trouble. The initial reporting didn't include details about the circumstances of those rescues. It also didn't include estimates of damage or cost, figures that will matter once the water recedes and the bills arrive.
The Forecast
The worst may not be over. Rain is expected across Victoria on Friday and Saturday. A flood watch currently covers catchments across much of central and eastern Victoria, a wide area that takes in far more than the city itself.
Conditions should ease on Sunday as the low-pressure system moves offshore. The easing is forecast to come from the west.
At least two more days of exposure remain. Rivers and creeks that handle one heavy downpour can behave very differently when rain keeps falling on already saturated ground. A flood watch isn't a flood warning, but it's the kind of notice that asks households and businesses to pay attention and act.
Why This Matters:
One afternoon of 25mm in an hour showed how fast normal city routines can be interrupted, and how much pressure falls on a volunteer-backed emergency service when they are. With the Bureau of Meteorology saying more rain is coming and a flood watch covering much of central and eastern Victoria, the next two days will test readiness. That means individual preparation, sensible attention to official warnings and state agencies' capacity to respond without being overwhelmed. Once the system clears on Sunday, the cost of the damage and response will come into focus. Taxpayers and insurers will want to know how well Victoria's flood preparations held up under pressure.
