Any thunderstorms that develop in these areas have the potential to produce localised heavy rain with intensities of 10-15mm/hr and small hail. However, about Gisborne and the eastern Bay of Plenty rain intensities of 10-20mm/hr and hail 10-20mm in diameter are possible.

Over remaining areas of the North Island and about the South Island from Nelson to northern and inland areas of Canterbury, there is a low risk of a few thunderstorms.

No thunderstorms expected over the remainder of New Zealand.

Where is "here"? Because I have seen hail and lightning and heard a fair amount of thunder.
