Severe weather conditions are expected to hit the Mackay region today.
Ex-tropical cyclone Oswald is dumping heavy rain on the Queensland coast, with falls up of to 200 millimetres possible in the area over the next six hours.
A flood warning has been issued for rivers and streams between Cooktown and Mackay, and wind gusts of up to 90 kilometres per hour are likely.
Janine Yuasa from the Brisbane weather office says parts of the Central Highlands and Coalfields will also experience wet and windy conditions.
"So it's going to be mostly north of Moranbah today and probably much of tomorrow as well but that will eventually spread south to maybe about Emerald on Friday, Saturday and they can expect some moderate to heavy falls in there as well," she said.
She says the unsettled weather will continue for several days.
"The low is probably likely to be around Townsville tomorrow, so that means the rain is spreading south and at this stage it looks like you're in for the rain to stick around at least into Friday but probably into part of the weekend as well," she said.
Mackay Mayor Deirdre Comerford says emergency crews are on stand-by and they will closely monitor conditions over the next few days.
"It's very important in particularly our locality that not only do we keep in touch with the weather bureau but monitoring those tidal movements," she said.
"As you know, in Mackay the last thing you need is a high tide and a storm event, so we monitor that because there are flood gates that need to be activated, as in dropped, so that we stop the flow."
