Widespread storms developed across South East Queensland yesterday afternoon(Wednesday 19/11/2014). Several severe storm cells developed including one which formed near Darlington and moved North North East across the city dumping a huge amount of rain. Another severe storm developed south of Crows Nest and moved through Esk, Kilcoy and onwards to the Sunshine Coast.

Are we in for a repeat of these storms today(Thursday 20/11/2014)?

The cell moving across the Brisbane area dumped torrential rain over a wide area, paralysing Brisbane’s CityTrain network. In 20 minutes from 4:00pm, 50mm fell at Archerfield. In the CBD 40mm fell in a 20 minute period from 4:12pm. At Fortitude Valley streets and the train lines were inundated. Cars in low lying frequently flooded areas of Bowen were covered up to the top of the wheels. In Fortitude Valley train station, several inches of water covered rail lines!

At Redcliffe just after 5pm wind gusts reached 106km/h and were sustained at greater than 50km/h for nearly 30 minutes! Across northern Brisbane trees were brought down and damage occured. A tree fell over train overhead powerlines at Nundah, halting more rail services!

At Toombul Shopping Centre, rain came through the roof leaving shoppers wading through centimetres of water on the floor. The accumulated precipitation image below from the Brisbane Radar shows the path the heaviest rainfall took through the city.

Here are some highlights of yesterdays observations:

  • Brisbane Rainfall to 9am: 56mm
  • Archerfield Rainfall to 9am: 87.8mm
  • Redcliffe Wind Gust of 106km/h, Sustained winds of 80km/h at 5:15pm
  • Cape Moreton Rainfall to 9am: 59mm

What made the storms so strong?

The atmosphere contained significant moisture today, from the ground up to high altitudes. This combined with instability to produce storms with high amounts of precipitation or rainfall. The instability is being produced by an elongated area of lower air pressure in eastern QLD, known as a trough.
