Heavy rain and damaging wind gusts lashed Brisbane this morning as a severe thunderstorm moved across the city. The city gained 10mm of rain in only 10 minutes as well as winds gusting up to 70km/h. The airport was even harder hit with 14mm of rain in 10 minutes and winds gusting to 85km/h. The arrival of the storm also saw a sharp drop in temperatures with the mercury falling seven degrees in 10 minutes. The heavy rain lead to flash flooding in parts of the city while the damaging winds felled powerlines leaving thousands without power. A trough crossing southeastern Queensland caused the storms to develop over St George around 5am before moving east through the Darling Downs. The storm then became more intense as it moved through the Southeast Coast district, bringing 13mm in just 10 minutes to Gatton. The thunderstorm brought huge amounts of lightning with over 4000 lightning strikes within 80km of Brisbane in under two hours. Severe thunderstorms remain a risk for Brisbane this afternoon. The trough is likely to cause further severe thunderstorms in the Brisbane area on Sunday, most likely during the afternoon.
