The weather bureau says a monsoon low in the Coral Sea off north Queensland will probably develop into a cyclone in the next 24 hours.
The low caused heavy rain and strong wind in the Torres Strait and northern Cape York yesterday but is now well off the east coast.
Weather bureau forecaster Bill O'Connor says the system could head back towards the coast early next week, but probably not as a cyclone.
"This system looks as if it really gets sheared apart as we get into the latter part of Sunday or Monday," he said.
"Then the low level part of the system will probably be steered back onto the coast, but it's whether it's going to be Cairns, Townsville - it could be anywhere from about Mackay to about Cooktown when it gets back onto the coast."
