A series of severe storm cells have impacted the state's south-east from the Gold Coast to Kingaroy in the South Burnett, with the Bureau of Meteorology (BOM) issuing warnings of "very dangerous" systems on multiple occasions.
Just after 8:00pm, the BOM warned of three more storm cells, two impacting the South Burnett and another "very dangerous" storm moving south of Toowoomba toward Warwick.
Brisbane escaped the worst of the weather, but earlier in the day another dangerous cell brought heavy rain to Mango Hill and Caboolture, north of the city.
As the first wave of storm cells moved off the coast in the afternoon, others appeared further west and swept their way toward the coast.
At one point, the BOM said flash flooding was likely and warned of an "immediate threat" of winds of more than 125 kilometres per hour.
Since midday, Energex recorded about 80,000 lightning strikes across the south-east region.
The lightning strikes left more than 5,000 homes without power and debris from the storms tore down 18 power lines across the region.
Energex senior communications advisor Ty Marega said Wednesday's storm had caused more damage than storms that hit the region on Tuesday.
"There's a lot more wind and lightning activity in this particular storm, so chances are we're going to have a bit more repair work to do," Mr Marega said.
At 8:15pm, 2,400 homes were still without power across a range of towns and suburbs from the Gold Coast to the Sunshine Coast.
Anyone experiencing a power outage is urged to call 13 62 62.
Hail has fallen in a number of locations, including at Biddeston near Toowoomba, Stanthorpe and west of Gympie at Crownthorpe and Merlwood.
Storms on Tuesday brought 72 millimetres of rain across Brisbane, with flash flooding reported in several areas during the city's wettest October day for a decade.
The strength of the downpour caused cars to become submerged in parts of Brisbane's east and south and swiftwater rescue crews were deployed to some areas.
BOM senior forecaster Peter Markworth told ABC Radio Brisbane on Wednesday that the latest round of thunderstorms would continue into the evening.
"It's very much a carbon copy of what we saw yesterday, with showers and thunderstorms to pop up through the mid-morning and then start to roll off towards the east coast as we get through the afternoon," Mr Markworth said.
"We are expecting super cells further out west, potentially making it over towards the coast," Mr Markworth said.ABC
