North Queensland is set to face heavy rain over coming days, with some spots expecting up to 500mm of rainfall, the Bureau of Meteorology (BoM) warned. The BoM has issued a severe weather warning for the Gulf region and will soon do the same for the Townsville coastal area. Flood warnings are active in the Gulf and parts of north-west Queensland. Senior BoM meteorologist Andrea Peace said places like Mount Isa had already seen between 30 and 80mm of rain recently, with some areas hitting 120mm. More rain, up to 100mm, is expected on Sunday. She described the weather system as "very broad" and "almost stationary," impacting Queensland for at least three to four days. The system will move eastward by Tuesday and Wednesday. Ms. Peace added, "Seeing totals in excess of 500mm broadly across the region this week is not out of the question." There is concern for livestock, with the rain compared to the 2019 Townsville floods that caused major inland flooding. Queensland Police Minister Dan Purdie noted preparations were underway to support affected areas, including plans to deliver fodder to livestock if roads become blocked. Moderate flood warnings cover Winton, where the Diamantina River is expected to flood on Sunday. Major flood warnings are in place for Walkers Bend, relating to the Flinders and Cloncurry catchments. Flooding is predicted for Cloncurry today. A second weather system will bring heavy rain near Townsville and Cairns. These areas have already seen about 100mm of rain recently, with 60 to 80mm more expected today and up to 200mm in isolated spots. Rain will intensify on Monday, reaching 70 to 120mm with some areas possibly getting over 300mm. BoM's flood team considers issuing warnings near the Bohle River north of Townsville. The wild weather results from a monsoon trough inland and a monsoon low offshore, fueled by very warm sea temperatures. Rain is likely to continue through the week but should ease later on, Peace said.
