UMBRELLAS at the ready, you're about to get satched.
Up to 100mm of rain is expected to fall over chunks of the state, with the Bureau of Meteorology expecting a fast and furious dose of rain between now and Sunday.
August is a notoriously dry month, but an upper-level low pressure system moving east from the top of South Australia is going to deliver the damp.
Swathes of south-east Queensland including Sunshine Coast, Ipswich and Toowoomba will receive between 40mm and 60mm of rain with up to 100mm in "isolated falls" hitting some areas.
Moving north, the Wide Bay Burnett is expected to cop up to 70mm, although there is a risk of 100mm in some places.
In Central Queensland, gardens will be watered with between 75mm and 125mm of rain, from Mackay and heading north.
BOM meteorologist Pradeep Singh expects this to be the biggest August rain since 2010.
"It's pretty massive," he said.
"It's something like what happens in the monsoonal season - figures of this kind don't usually happen.
"There is a very good chance that total rainfall records will be broken."
From Sunday evening, the bulk of the rain will have passed.
