Queenslanders are being urged to prepare now for heavy rainfall and possible flash flooding in coming days.

The Bureau of Meteorology (BoM) has forecast heavy rainfall and thunderstorms across large parts of the State from tomorrow and extending into the weekend, with severe weather stretching from Fraser Island to the New South Wales-Queensland border and extending inland.

Minister for Fire and Emergency Services Bill Byrne said residents needed to take steps now to prepare their properties and reconsider travel plans in the event of bad weather.

“This is an unseasonal weather event, and residents need to make sure they have plans in place to cope in case they are affected,” he said.

“Parents must supervise their children closely and ensure they stay away from drains, culverts and any flowing water.”

Mr Byrne said motorists needed to have a Plan B in place if travelling on the weekend, including finding alternative routes in case roads were flooded.

“Residents need to pay close attention to weather reports and local conditions before getting behind the wheel,” he said.

“If the road is flooded, forget what car you drive. No-one can predict floodwater or what is happening underneath, so it is important motorists never enter a roadway covered with water.”

“Remember: if it’s flooded, forget it. This simple rule will keep you and your loved ones safe.”

Queensland Fire and Emergency Services (QFES) Commissioner Katarina Carroll said residents should tune-in to their radio, televisions and social media when poor weather is forecast to ensure they have the latest information.

“Residents can also take steps before a severe weather event hits. This includes clearing their gutters and ensuring there are no branches overhanging their house that could fall and prevent water escaping,” Ms Carroll said.

Ms Carroll said State Emergency Services (SES) crews would be on standby to respond if needed.

“SES volunteers attend to hundreds of requests for help during peak storm activity and ask that those requiring assistance be patient.”

Residents who cannot clean up their own property and require storm and flood emergency assistance should contact the State Emergency Service (SES) on 132 500. In a life-threatening emergency dial Triple Zero (000).
