Rain causes flash floods, delays NAB match

The severe thunderstorm that drenched Geelong just after 5.30pm on Wednesday dumped more than 50 millimetres of rain in an hour, delaying the start of a NAB Challenge AFL match.

The downpour, which caused localised flash flooding, arrived just hours before St Kilda and the Western Bulldogs’ were due to play at Simonds Stadium.

Ground staff were left scrambling in an attempt to ready the ground for a 7.10pm start, after what was described as ‘‘a mini flood’’.

Bureau of Meteorology senior forecaster Scott Williams said the intense thunder storm arrived without warning.

He said it appeared to develop above Geelong in about 10 minutes and was so high that the radars failed to detect it.

He said in his 30 years at the Bureau, he had never seen anything like it.

‘‘I don’t think I’ve seen a classic one like this,’’ he said.

‘‘It’s pretty rare in Victoria to get one of these … instead of curling anti-clockwise, it came in clockwise and with height.’’

Mr Williams said 54 millimetres of rain was recorded at Geelong racecourse between 5pm and 6pm, with the majority falling between 5.20pm and 5.53pm.

After dumping down on Geelong, the storm moved towards Ocean Grove by 6.30pm before heading out to Queenscliff and out over the bay.

Mr Williams said Bureau staff were monitoring it, in case it gained severity as it approached Mornington Peninsula.

The Geelong thunderstorm was one of two cells which accompanied the cool change.

The other event hit a less populated area around Ballan, near Bacchus Marsh.

Melbourne meanwhile experienced light rain with the cool change, which will last the rest of the working week.

Bureau of Meteorology data showed rain fell in the city and northern suburbs, the fourth time rain had been recorded in Melbourne this month.

About 2 millimetres of rain in the CBD and 3-5 millimetres in the suburbs by Wednesday afternoon.

Showers and cool weather are forecast for the rest of the week, with Thursday and Friday set to reach a maximum of just 20 degrees.

There is also a chance of thunderstorms in the early hours of Thursday morning, with southern areas such as Geelong most likely to be affected.

The weekend forecast is for clear and warm conditions, with a top of 23 degrees on Saturday and 27 degrees on Sunday.
