The rain is moving through the North Island faster than forecast as a big high near Australia expands faster helping push the rain through and limiting the chances of a lingering low over the North Island. It’s always been a bit of a messy forecast but the latest shows the high (which was initially forecast to only cover the South Island on Monday) pushing into the North Island for the start of the week.
A front with heavy falls is still crossing the North Island today, tracking eastwards.
Behind it is a colder change which is spreading north up the South Island and moves into the North Island later today and into Monday.
