Wet season kicks in to QLD's tropics!

Last week it was SE QLD, but now QLD's North Tropical Coast is copping a soaking! Strong onshore winds are loading the coast with moisture while a low pressure trough sparks showers and storms.

Together, the two weather features have delivered massive rain totals to the region in 24 hours to 9am this morning: Menavale 199mm, Bolinda 113mm, Corsis 113mm, Goldsborough Valley 105mm, Gordonvale 98mm, Tully 74mm, Topaz 74mm.

Over the next 4 days, over 50mm is expected north of Townsville with over 100mm between Cairns and Cardwell. The rain is expected to ease from Thursday onwards.

So what can northern QLD expect this wet season? Last year, QLD experienced its wettest year on record largely due to one of the strongest La Nina's on record. It looks like La Nina is back for another so northern and eastern Australia can expect above average rainfall. But it is important to note that this La Nina is much weaker than last year so a repeat of last year's record-breaking rainfall is unlikely.

What about cyclones? The long-term average for eastern Australia over the November- April period is 3-4 cyclones. The latest seasonal outlook from the Bureau of Meteorology suggests a 65% chance of exceeding this average in eastern Australia, with an 80% chance of above average tropical cyclone activity across the Australian region this season.
