The BOM says some areas of central and southeast Queensland will be impacted later today by extremely harsh thunderstorms with giant hail, destructive winds and flash flooding.
Clouds developed this morning in the eastern Darling Downs and are forecast to move east in the early to mid-afternoon and into the evening to develop into severe thunderstorms.
In New South Wales, the storm is driven by a low-pressure system that stretches through up the east coast to Queensland, stopping short of Proserpine, north of Rockhampton.
BOM forecaster James Thompson said that along and east of the Great Dividing Range, serious thunderstorms were feasible. [Those areas] today have the strongest chance of a severe thunderstorm, so a fairly significant portion of the east coast, “said Mr. Thompson.”
The BOM also warned of the potential for flash flooding in Brisbane, which is forecast to dump more than 60 millimeters of rain into the city an hour later this afternoon.
The flooding would not be widespread, however, Mr Thompson said. It means the catchments are somewhat more equipped than they were earlier in the week with the recent rainfall, so we may see flash flooding with heavy rainfall, he said.
The storms are forecast to spread into Western Queensland, the Darling Downs east of Dalby and Chinchilla, and the Central Highlands east of Clermont.
It may also impact areas south of Gladstone, Biloela and Thangool, and parts of the Sunshine Coast, Brisbane and the Gold Coast.
The extreme thunderstorm activity was expected to include hail and damaging winds in some areas.
“Mr Thompson said,” Big to giant hail in excess of two centimeters, damaging wind gusts in excess of 90 kilometers per hour and precipitation that can lead to flash flooding.
Today, these isolated severe thunderstorms are a potential risk and we ask individuals to keep an eye on any alerts on the official website.
The safest thing you can do to plan is to take any debris that could fly around, indoors, clear any gutters, and keep any valuables out of the way of any storms to ensure that nothing that could hurt someone else or their property is going to fly around.
Later this evening, the storms are expected to move out of South-East Queensland and a minor wind shift early next week means that next week much of the extreme thunderstorm activity will not impact the south-east region.
For most of Queensland, tomorrow’s decent weather is just the slight possibility of tomorrow’s thunderstorms along the seashore of Capricorn, said Mr. Thompson.
