Far north Queensland is facing fresh weather threats as a tropical low bearing down from the Solomon Islands could develop into a full tropical cyclone by the end of the week, just as the region recovers from weeks of relentless monsoonal rain.
The weather system is currently positioned south of the Solomon Islands and moving in a westerly direction. The system is currently designated as 29U or possibly evolving toward 34U, positioned roughly 900 kilometres east of Cairns and drifting westward. Atmospheric conditions in the Western Pacific can increase rainfall over northern Australia, particularly northern Queensland.
A tropical low is stationed northeast of Cooktown and is slowly tracking westward towards the Queensland coast, with Cairns likely to cop the brunt of the impact when the system is set to cross the coast on Friday morning. The system is expected to cross the Queensland coast later in the week, around Friday.
Favourable conditions such as warm sea surface temperatures and low wind shear could propel this low into a named tropical cyclone by mid-week. The Bureau of Meteorology rates the low pressure system as a moderate chance of becoming a category one cyclone, putting the Wet Tropics between Cooktown to Palm Island on watch.
The timing is perilous for a region already saturated by an unusually active wet season. Heavy rainfall has already saturated the region, with locations like Mossman recording over 225 millimetres in a single day. Heavy rainfall and flooding have resulted in extensive and ongoing road closures across Queensland, particularly across central and eastern areas, with many moderate to major flood warnings across eastern and central Queensland.
Senior meteorologist Angus Hines said the watch zone would likely endure gale force winds of up to 100km/h, but heavy rainfall was expected to impact a much wider area. Recent monsoonal activity has left catchments swollen, heightening flood risks before the system even organises further.
The system poses particular challenges for inland communities. It is unwelcome news for graziers, who have already lost an estimated 100,000 stock after major flooding hit the Gulf Country in January. Meteorologists noted frequent bouts of wet weather across the north and interior of Queensland in recent months, with a prolonged, ongoing flood situation, and rivers running extremely high at the moment.
The Bureau of Meteorology forecasts the system will track westwards towards the Gulf of Carpentaria over the weekend. Residents and authorities have been advised to monitor the latest forecasts from the Bureau of Meteorology as the system develops.
Whether the system fully intensifies into a named cyclone or remains a tropical low, the risk of significant rainfall and flooding across far north Queensland and adjacent areas remains acute. The convergence of saturated soils, swollen rivers and another weather system arriving within days presents compounding challenges for emergency management and livestock operations across the region.
