Severe storms have ripped through Melbourne and Canberra on Thursday morning, delivering brief but heavy downpours in many suburbs, with the strong chance of more to come in both cities, as well as Sydney.

The storms in Canberra and Melbourne struck just after 9 am, as you can see on the radar loop below which covers the period between 8 am and 10 am Thursday.

The timing meant that commuters weren't too badly affected, however as mentioned, we haven't seen the last of the storm activity for the day.

The BoM has issued numerous warnings, the latest being a severe thunderstorm warning for the Melbourne area at 9:53 am Thursday, noting that the first severe thunderstorm has cleared to the east of the metro area, but another storm is approaching the Ballarat area and may become severe.

You can see that next storm marching through Ballarat in the general direction of Melbourne in the two-hour loop below, which shows the radar from 8:30 am to 10:30 am.

At the top of the loop, you can also see the storm that hit Canberra heading eastwards with bands north of it heading towards the greater Sydney metro area.

How much rain has fallen in this morning's storms?

We wrote on Wednesday that the city and most suburbs of Melbourne only saw a millimetre or so of rainfall on a night when much heavier rain fell further north.

The city of Melbourne has again only seen 1.4 mm in Thursday's first storm, while up to 15 mm fell in the outer eastern suburbs. These totals may well increase in coming hours as the next band of storms approaches.

Meanwhile Canberra has received a total of 15.4 mm on Thursday morning as we write this story, and that tally also seems likely to increase with another band approaching the national capital.
