That's a good rain event Scott. 300+mm two days in a row is quite rare. I can only remember that happening once here, back in 1994 just a couple of years after we moved into the house. It made me change a few things to do with drainage.

We're sitting around the 100mm mark out of this so far.

Edit: I looked it up, in 1994 the culprit for that flood event was Cyclone Sadie in the gulf.
