BOM Queensland forecasters expect record rainfall in May as central interior comes under fire

There is again a risk of major flooding in Queensland, with May rainfall records ‘likely’ to be broken as three weather systems collide.

Northern and central Queensland are in the firing line, while parts of the southeast could also be saturated when the falls intensify from around Tuesday.

And the heavy rain could continue over the weekend as part of a “long-lasting” severe weather event, said Felim Hanniffy of the Bureau of Meteorology.

“This is caused by a trough that will deepen inside over the next few days,” he said on Sunday.

“And we’re going to see another form of trough on the coast, around the southern parts of the northern tropical coast.

“It’s a combination of these two systems, compounded by a slow-moving upper feature, that will really increase rainfall totals in central Queensland.

“A lot of moisture is pumped in from the Coral Sea, and then you have the top feature – a cooler loft that lifts all that moisture into the trough systems.”

He said the central interior would likely be the “center of the bullseye” for the wild weather, with around 200mm falling over three days.

The southeast could receive 80 to 100 mm.

Hanniffy said the weather bureau is likely to issue a flood watch covering most of the east coast and central regions, while a wide-ranging severe weather warning is also likely.

“We already had very wet Mays with heavy rains in 2017, in parts of the central areas, and in 1990, 1983 and 1977,” he said.

“But it looks like this event is likely to eclipse all those previous very wet May spells.”
