The Townsville flood of January-February 2019 was, like cyclones Althea and Yasi, one of the extreme weather events which define people’s lives in the city. Two months later, “How did you go in the floods?” is still the first question we ask friends we haven’t seen for a while. There’s a lot for Green Path to say about it but whatever we publish now will be incomplete so we will update and extend it as appropriate, in separate posts if justified by the amount of extra material.
Let’s begin with an overview of theweather event and its immediate consequences.
The weather event
A low in the monsoon trough over the Gulf became a rain depression and drifted South and East until it settled over Townsville, where it stayed much longer than “normal” (we will have to return to that concept later) and dumped an inordinate amount of rain on us over about ten days – say 29-30 Jan to 7-8 Feb.

We’re officially in Winter now and I reckon we moved definitively into the Dry season a fortnight ago, so it’s worth looking back at the Wet and seeing what’s likely to happen to our water supply in the Dry.
Wet season rainfall and the year to come
BoM climate data reveals that our rainfall so far this year, Jan – Feb – Mar – April – May, was 118 – 285 – 343 – 10 – 2 mm, for a total of 760 mm.
The Townsville region received quite a deluge between mid February and early March, after a dry start to what we hoped would be a good Wet. Green Path recently posted photos of the Town Common after rain, and here are some from Hervey’s Range to the West of the city.
I’m not going to claim credit for it, of course, but my post about rainwater tanks was followed almost immediately by the best rain Townsville has had for years, with totals like 250 to 600 mm over a week or so, depending on exactly where you looked. Ross Dam went from about 15% to over 80% – but I will say more about that in another post.
Easter seems to me to mark the usual turning point between Wet and Dry seasons here in Townsville, and it has certainly seemed so this year. Cyclone Debbie was looming as we left for Bali on March 25 but by the time we returned, a week ago, humidity had dropped right off, nights were noticeably cooler, the frangipanis were losing their leaves and the prospect of more real rain seemed to have evaporated.
