Severe thunderstorms building in QLDRob Sharpe, Saturday November 17, 2012 - 18:05 EDT
A severe thunderstorm lashed Brisbane this morning with heavy rain and damaging wind, with further severe storms spreading across Queensland this afternoon.
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. Gatton gained its heaviest rainfall since July with 17mm, with more likely late this afternoon or evening.
The thunderstorm brought huge amounts of lightning with over 4000 lightning strikes within 80km of Brisbane in under two hours.
Severe thunderstorms are likely to impact large portions of Queensland this afternoon and evening due to the deep low pressure trough. A very long band of thunderstorms stretched from the WA Kimberley to the Gulf Country and to northeastern NSW during the afternoon.
These storms have already become severe with 4cm hailstones reported in Millmerran. Thunderstorms bring the risk of destructive wind gusts, large hailstones and heavy rain.
Brisbane is likely to receive further thunderstorm activity in this bout of storms with the risk of being severe again.
