A deep onshore flow has continued to drive heavy showers onto the north Queensland coast, bringing the highest falls in a year for some places. A large high pressure system centred over the Tasman Sea is directing a deep and very moist flow over eastern Queensland. This is combining with a low pressure trough to trigger heavy showers. The highest totals have been north of Mackay where falls exceeded 100mm. In the south falls were generally below 10mm. Mt Sophia had a highest total with 126mm. Proserpine along the Central Coast recorded 96mm to 9am Saturday. This included 5mm in 10 minutes and was the highest daily total in a year. For other areas it was the most rain received since March last year. Mackay picked up 79mm while Cape Flattery had 54mm with 5mm falling in 10 mintues. Further north 57mm reached the gauge at Cairns and Cooktown. At Cooktown 8mm fell in just 10 minutes. Although the high pressure system causing the moist onshore flow will continue eastwards it will quickly be replaced by another, leading to similar conditions for at least a few days. On Saturday widespread falls of 20-40mm are expected north of about Mackay with falls exceeding 60mm likely in some areas, especially along the North Tropical Coast and Peninsula. On Sunday heavy showers will continue in much the same area and will continue through most of next week.
