New Zealand was affected by tens of thousands of thunderstorms last week and all of them delivered significant heavy downpours inland, some with flash flooding.

The map below clearly shows you where the bulk of the daytime downpours formed – it’s a helpful map as it shows why some coastal fringes in New Zealand are drier than average while inland areas are not.

More rain is coming in the days ahead, with at least two low pressure systems crossing New Zealand between Wednesday and Saturday.
