Well that's disappointing.

Big storm moving in and all my rainwater tanks are full.

I really need to build bigger tanks, hopefully before next Monsoon season.

Peter, is this a good time to use some of that stored water to prewet the soil around your place as much as possible so as to try and get better rain infiltration?  Just a thought as I have no idea how dry or not your soil is, but they're saying they expect a lot of run off due to hydrophobic soil surfaces due to dryness.

I think that what Peter's about to get is going to overwhelm the soil's absorption capability either way. It's a decaying hurricane and it reminds me an awful lot of this day 35 years ago....

Can't have too many tanks! I say that here where we normally get 1.2 m a year and no real pronounced dry season to speak of. All it takes is a few dry weeks in summer (or spring, for that matter) and conventional growers start getting nervous.
