Heavy rain over large swathes of Queensland this week could spark flash flooding, with the same wet weather system bringing less intense but prolonged showers to Sydney for up to five days.

The Bureau of Meteorology has said western and inland parts of Queensland, as well as the tropical far north, will receive the most rain. Totals could reach 250mm in some areas and pose a prolonged flood risk for areas of the state that are already on flood watch, particularly in the south.
