A complicated system moves into NZ this week bringing pockets of severe weather thanks, in part, to two power high pressure zones in the mix too. They will all work together to produce some heavy rain in both main islands (but it’s broken up) along with windy northerlies which will become sub-tropical and milder over the next 48 hours.

We take a look at what is driving this weather, the areas most inline for heavy rain and wind and when it clears away.

We’ll update this again on Tuesday as we fine tune the data further – the heavy rain is a developing situation.
