Cyclone season may not officially start until next month but one may soon develop off the Queensland coast, marking a 50-year first.

The Bureau of Meteorology is monitoring a storm system off the Solomon Islands with a tropical low expected to form over the coming days.

The bureau says the low may then move into the Coral Sea with a “moderate” chance of it developing into an unprecedented cyclone from Monday.

It would mark the first time a tropical cyclone has developed in the Coral Coast in the month of October since reliable records began in the 1970s.

The bureau said it would continue to monitor developments off Queensland’s northeast coast, releasing a new seven-day forecast.

However if a cyclone forms in the coming days in the Coral Sea, it is not expected to threaten the Queensland coast.

“There is a chance that (a tropical low) may move into the northeast Coral Sea next Monday or Tuesday,” a bureau spokesperson told AAP.

“Any system is forecast to remain a long way from the Queensland coast and no direct impacts are expected.”

The bureau warned this month Queenslanders could still expect flooding and tropical cyclones despite El Nino promising a hotter and drier summer for Australia.

The cyclone season is usually from November to April, typically peaking in Queensland in February and March.
