Agreed. September can be a dry month outside of tropical mischief. But we have an oncoming Nino. Depending on how/where it sets up and countless other factors, it could still be a mild, snowless winter. But I'm not concerned about a dry winter. I think once we get into October, the faucet gets turned on and it's wet until next spring.
(Of course I can't forecast my way out of a wet, paper bag so everything I said above could be dead wrong. )
