"There was some flash flooding in the South Morang and Mernda area after about 50mm of rain fell during the storm.
"Thankfully there have been no injuries and no reports of SES crews having to rescue people from flood waters, which means people are not driving through the floods."
Lightning stopped planes from landing and taking off at Melbourne Airport, causing long delays.
Airport spokeswoman Anna Gillett said it was a normal safety procedure because of the wild weather.
While Epping police station was closed due to storm damage.
Weather Bureau senior meteorologist Phil King said 60mm had fallen in Mernda - 47mm fell in one hour.
"That's above our flash-flood warning of 25-30mm an hour," Mr King said.
Sunbury had 30mm of rain in 20 minutes.
"These storms are producing some really heavy rain that will continue throughout the night."

The weekend is expected to bring more settled weather before more storms are predicted for Monday and Tuesday.
