Some nice Cu forms to the NW this afternoon around the Mt. Peel to the 4 Peaks areas.
Sadly, not delivering 'fruit'

A fairly mild September overall, although much of the Sth Island started cooler, but ended much warmer. Well above normal rainfall around the central Nth Island and Nth Canterbury/Marlborough, with some places receiving more than double their normal rainfall. Interesting to note Mahia Peninsular's 180mm, compared to just 26mm and 22mm further down at Napier and Hastings respectively.

I thought it would be, so as far as I'm, concerned, I will give the maximum to Hastings on the 25th.
