A tropical low pressure system off the coast of Queensland poses a significant risk of heavy rain and flooding in the coming days. The Bureau of Meteorology has advised that this system, designated as Tropical Low 12U, may strengthen into a tropical cyclone as it approaches the coastline. Regardless of its classification, substantial rainfall is expected to impact large areas of the state.
Currently, two tropical low pressure systems are being monitored across northern Queensland, straddling both sides of the Cape York Peninsula. While Tropical Low 12U is the primary concern, Tropical Low 13U in the Gulf of Carpentaria is anticipated to enhance rainfall over parts of the Peninsula before diminishing. A band of rain between these two lows has already resulted in moderate to heavy rainfall overnight.
Forecasts indicate that as Tropical Low 12U moves toward the coast, it will bring significant rainfall to northern Queensland. The tropical cyclone forecast team has assessed a moderate risk—between 40% and 50%— that this system could develop into a tropical cyclone before making landfall. In anticipation of these conditions, a Severe Weather Warning has been issued for parts of the east coast, where heavy rainfall and damaging winds are likely.
The warning area encompasses regions from north of Cooktown, extending through Port Douglas and Cairns, down to Mackay, Ayr, Bowen, and as far south as Hamilton Island. This area could experience intense rainfall, with forecasts suggesting up to 100 mm within a six-hour period on Friday and potentially 250 mm over 24 hours. Some locations may see even greater totals.
Weather conditions are expected to deteriorate on Friday, with a particular focus on the weekend when the system is likely to cross the coast, bringing widespread rainfall. This rainfall could extend from Port Douglas northward, down the east coast to Mackay and beyond, impacting areas such as Capricornia and potentially reaching as far inland as Winton and Longreach.
The anticipated rainfall is particularly concerning given the recent wet conditions in the region. Heavy downpours since Christmas have already caused significant flooding in northern Queensland, especially along the Flinders River near Winton, where major flooding is reported. Moderate flooding has also been observed in the Norman River, Georgina River, and Herbert River.
A Flood Watch has been issued, highlighting areas where further flooding could occur based on rainfall forecasts in the coming days. Residents in Central and Northern Queensland are urged to stay informed about the latest weather and flood warnings, as flooding poses risks to property, life, and livestock while potentially leading to road closures and the isolation of communities.
The agricultural sector could also face significant challenges due to the expected heavy rainfall. As the weather system develops, it is crucial for residents to remain vigilant and monitor updates. The Bureau of Meteorology will provide ongoing information through its website and app, ensuring that the public is kept informed of any developments throughout the weekend and into next week.
