Queensland's central and north coasts have copped a late season soaking, with some parts having their heaviest rain in months. A low pressure trough situated off the QLD coast has combined with humid onshore winds to bring the heavy falls. In the 24 hours to 9am, Low Isles picked up 101mm. This is the heaviest rain since January after recording well below average rainfall over the past two months. North of Low Isles, Daintree Tee had a whopping 166mm of rain. It was the heaviest April rain in 15 years for Mackay Airport and 14 years at Willis Island, with 93mm and 85mm respectively. The downpour continued during Wednesday morning, with Mackay Airport seeing a further 20mm by midday, pushing the monthly total well beyond the monthly average and making it the wettest April in 13 years. Hamilton Island has also now seen its monthly average rain, after 53mm fell in the gauge. Heavy falls are expected to continue along the coast over the coming days as the system moves slowly southeast. The wet weather should last until Saturday, although the heaviest falls should be on Wednesday and Thursday. By time Sunday rolls around, rainfall will have eased significantly although some areas between Cairns and Bowen may have seen as much as 300mm.
