Just a week short of the first anniversary of the 2019 North Queensland floods that resulted in more than $2-billion in damages, 7,000 houses flooded, three deaths, the drowning of 500,000 head of cattle and the closure of the Mt Isa Line for three months, a similar Gulf of Carpentaria monsoonal low system has begun dumping heavy rain across the same regions impacted in 2019. Rainfall figures of 300-400mm are expected over the next four days, with isolated falls of up to 900mm between Bowen and Cardwell and across the North West. So far the heaviest rain has been around Mackay, north of Townsville and around Mt Isa.
The Mt Isa Line has been reported to have been impacted by flash flooding in a number of locations between Charters Towers and Mt Isa today, the parallel Flinders Highway has been closed since yesterday, as has the Landsborough Highway between Winton and Cloncurry. Significant river flooding in the Flinders River (the primary source of damage to the Mt Isa Line last year) has not yet occurred, but may do so tomorrow.
Major flooding between Mackay and Ingham, impacting the North Coast Line and Bruce Highway is expected to occur as rainfalls increase between Monday and Thursday.
