Severe thunderstorms have lashed parts of Victoria, including Melbourne’s east, with authorities warning flash flooding and large hailstones are likely.
Thunderstorms were detected near Croydon, Ringwood, the area northwest of Werribee, KooWeeRup, Bacchus Marsh and St Andrews about 2.40pm on Friday.
An hour later, they had hit Kilmore, with the Bureau of Meteorology saying the conditions were moving east to southeast.
She Oaks near Geelong also recorded 54mm of rain within about 50 minutes.
The underground car park of Cranbourne Park shopping centre in the south-east of the city was among the buildings flooded, Twitter users recorded. Flooding was also reported on the Monash Freeway, causing major delays.
The bureau issued a severe thunderstorm warning for Melbourne’s outer east, along with parts of the inner east and the city’s north.
“Heavy rainfall that may lead to flash flooding and large hailstones are likely,” the warning read.
The State Emergency Service urged people to remain alert, particularly those in fire-affected areas where heavy rain could pose the risk of landslides and debris strewn across roads.
“Flash floods can happen quickly, without warning and it is important to never enter or drive through flood waters, as it can take just 15cm of water to float a car,” SES State Agency Commander David Baker said.
Meanwhile, high winds continued to hit Lord Howe Island as the remnants of ex-cyclone Uesi moved south.
Uesi passed directly over the island in the Tasman Sea on Thursday night, bringing winds of up to 154km/h and leaving behind a trail of fallen trees, blocked roads and damaged buildings.
The Bureau of Meteorology senior forecaster Jake Phillips said the worst of the storm had passed and would continue to ease on Friday night, with wind gusts peaking at 90km/h.
The Lord Howe Island board chief executive, Peter Adams, said the damage wasn’t severe and no injuries were reported.
“We had all this extreme weather and then this eye of the storm calm,” Adams said on Friday. “It was quite eerie. You could hear the surf pounding the reef but the wind had calmed a bit.”
Adams said the island, home to almost 350 people, was set for a return to glorious weather over the weekend.
The storm was due to pass over Sydney’s coast later on Friday and early Saturday, bringing dangerous surf conditions.
A hazardous surf warning was in place for much of the New South Wales coast on Friday and for the Hunter, Sydney, Illawarra, Batemans Bay and Eden on Saturday.
Parts of NSW are facing more wet weather over the weekend after last week’s deluge, particularly the bushfire-ravaged south coast, the southern tablelands and western Sydney.
Phillips said rain was likely to set in on Saturday afternoon but would be variable in some places due to thunderstorm activity.
The rain has brought much-needed relief for firefighters, with the NSW Rural Fire Service confirming there were no uncontained fires for the first time this season. There were still 25 fires burning south of Sydney.
