South-east Queensland is bracing for more storms on Tuesday after the region was hit with a severe weather system overnight, causing major flash flooding to bayside areas.
State Emergency Service crews responded to at least six calls for help after cars became trapped in floodwaters.
Two people were rescued from a car trapped in floodwater at Sheldon in the Redlands region just before 7pm and a person was rescued from the roof of a car on Springacre Road at Thornlands.
“Very dangerous thunderstorms moved in just to the east and south-east of the Brisbane area and are moving out towards the coast,” meteorologist Shane Kennedy said earlier.
“Well above the heavy rainfall thresholds into the intense rainfall, so a very dangerous amount of rain falling in a short amount of time there.
“It’s been quite an active evening for sure.”
The SES received 170 calls for help in the south-east overnight.
Meteorologist Shane Kennedy said thunderstorms, heavy rain and possibly hail could hit the region again on Tuesday afternoon and into the night.
“The trough sitting inland is still likely to persist there, so the triggers will likely have those storms firing once again, unfortunately,” he said.
“At this stage, a slightly lower risk in terms of severity, but there will certainly still be the risk of seeing those potentially severe thunderstorms, both bringing heavy rainfall, damaging wind gusts and potentially some large hail as well.”
He said there were four storm cells looming over the south-east coast.
“Alexandra Hills has had 191 millimetres since 9am yesterday and 140 millimetres of that fell in two hours, so quite intense rainfall there for a couple of hours,” he said.
Residents in Brisbane’s southern and eastern suburbs assessed the damage to their homes and cars on Tuesday morning after more than 100 millimetres of rain fell in an hour on Monday night.
Between 6-7pm, 105 millimetres fell just south of Beenleigh in Logan, while 106 millimetres was recorded at Alexandra Hills on Brisbane’s bayside.
A trough further inland triggered a lot of the storm activity, which tracked across the south-east coast, hitting the Redlands and Logan before affecting parts of the Sunshine Coast.
