After a very dry December, Queensland's Tropical Coast is finally getting soaked with some places picking up more than 100mm, with further heavy falls on the way. An unstable southeasterly airflow is combining with a trough over the nation's eastern interior to bring about the unsettled weather across the region. Over the past few days, the area between Mackay and Gladstone has picked up the heaviest falls. Samuel Hill has collected 183mm over the past three days, its largest three day total since March last year. Rockhampton has recorded 89mm since Tuesday, also its biggest three day total since March. Yesterday and overnight, the region around Mackay was the wettest. While Mackay itself only picked up 21mm, elevated areas west of town recorded much higher totals with widespread falls 100-to-150mm in the 24 hours to 9am. Up to 202mm was recorded at Gargett, its highest daily fall in three years. The Tropical Coast will continue to be drenched over the coming days, although the focus of the heaviest rain will edge gradually north. The Mackay region is likely to see the most rain again today, however over the weekend places from Ingham and north will see the heaviest falls, with 100-to-200mm possible in places. From early next week, heavy totals are likely to remain a risk over the region as tropical activity increases over the region. By the end of the fortnight, many places are likely to be sitting comfortably close to or above their January averages.
