Parts of Queensland's coastline are in for a two-day drenching as heavy rain and isolated thunderstorms move across the state from Thursday.
The Bureau of Meteorology has issued flood watches for coastal catchments between Tully and Gladstone, stretching inland to parts of the Burdekin and Fitzroy catchments, as well as southwest Queensland.
Meteorologist Lauren Pattie said there was a system approaching through state's southwest as well as a trough tracking towards the north Queensland coast from the Coral Sea.
Together, they were likely to bring showers across Thursday and Friday and could net a possible two-day total of 400mm.
Ms Pattie said the area stretching from Cardwell down to Saint Lawrence was most likely to experience heavy deluges - widespread 25-35mm falls, with sporadic 200mm downpours - with inland showers also expected.
She said while the 400mm two-day total could eventuate, it was likely to be "very isolated" and fall over higher regions.
The bureau said catchments affected for ex-Cyclone Debbie were forecast to see "significantly lower" flood levels than during the disaster.
