This looks like a very similar event to what happened on Aus's east coast. 300mm of rain in a 24 hr period with the storm described as being 'like a tropical cyclone' in terms of the rainfall. It has resulted in at least 300 deaths - due to the extreme rain but also due to inadequate infrastructure.

There's something going on with these sub-tropical low pressure systems - they are becoming bigger/more deadly. It's time to give them a name and plot their paths.

The other learning is for govts to get their heads out of the sand. It's no good just saying it's 'unprecedented' every time and not doing anything.

It's one thing to talk about climate change action and 'reducing emissions by 2050' but that still leaves us with the here and now.

The reports on the SA floods talk about poor drainage - that's the same problem in Australia where the drains are a joke. It's quite a simple thing to do - doesn't involve fancy tech - fly to
Taiwan and take a photo on your phone if you can't work it out - but it's not as glamourous as a new freeway so it always gets shuffled to the bottom of the pack.
