The sub-tropical airflow behind ex-cyclone Winston remains over the upper North Island today, with more downpours moving around.

The first of the tropical rains set in across Saturday PM in many parts of the upper North Island, then eased overnight.

So far Sunday morning has been cloudy and humid, but mostly dry for the north.  However Northland has downpours and some are already heavy between Kaitaia and Whangarei.

Meanwhile, out west in the eastern Tasman Sea, more downpours are forming and developing – much like we saw on Saturday afternoon.  These downpours are moving east to south east into Northland and towards Auckland, Waikato and Waitomo regions.

It’s not a widespread band of rain – it’s hit and miss downpours with drizzly and dry patches in between.

Many northern areas may have cloud and even the odd sunny spell today – but more downpours are developing amongst the humid cloudy weather, on top of the showers spreading in from the Tasman Sea.

The week ahead sees high pressure trying to push in nationwide – but this ‘bubble’ of tropical air at the top of New Zealand may hang around for a couple of days – and may hang around Northland for much of this week with humid easterlies and the odd tropical-like downpour.
