Thunderstorms expected to affect Brisbane through the week

The Bureau of Meteorology said Brisbane will face a week of humid, rainy weather with a chance of thunderstorms, beginning on Wednesday. Senior meteorologist Jonathan How described Wednesday as “another unsettled and stormy day across the city,” noting that the morning will be overcast before becoming warm and humid later in the day, with thunderstorms likely to develop from mid-morning onward.

“The main sort of focus point for us will be the possibility of severe thunderstorms throughout the afternoon and evening, pretty much the entire south-east Queensland today,” How said.

Storms and showers are forecast for the next seven days, with Wednesday expected to be the most significant. Potential impacts include damaging winds, heavy rainfall, large hail, and flash flooding, especially in areas where the ground is already wet.

“Today’s storms could bring damaging winds, pockets of heavy rainfall, and large hail,” How said.

A risk of additional showers and thunderstorms remains on Thursday, while Friday is expected to be milder. More widespread storms are forecast for Saturday and Sunday, with Sunday potentially bringing the highest rainfall. Dry air is anticipated to move in from mid-next week, reducing the threat of storms.

“That’s when we see some dryer air pushing across the south of our state,” How said.

The meteorologist warned that even 20 to 30 mm of rain could trigger flash flooding in already saturated areas, and consecutive storm days would increase that risk.

“The rain today will certainly wet the soil and start to increase the water levels around,” How said.

Residents are advised to stay alert to weather updates and heed any flood warnings issued by authorities.
