Areas of heavy rain, which may lead to flash flooding, are likely to develop about the coast and ranges between about Lockhart River and Ingham during Tuesday night and are likely to persist through Wednesday.
The low pressure system is expected to head out into the Gulf of Carpentaria but not expected to impact North West Queensland.
