The low in the eastern Tasman Sea, near New Zealand, doesn’t look very spectacular on the satellite map. So why is that?
Basically the low is fed by moist air that it pulls down from its north eastern quarter.
With the low so large and wide, all the moisture is being pulled down on the eastern side of New Zealand – and the air is mostly dry when it passes over the Southern Alps and gets pulled back towards the centre.
The centre of the low has been fairly unimpressive on satellite images, almost impossible to pick at times by the untrained eye.
However the low is likely to generate more moisture today with some heavy showers move into the west coast of the North Island this afternoon and into tomorrow.

We have low to moderate confidence of isolated thunderstorms. Certainly a high chance of heavy, squally, showers though.

“Certainly a high chance of heavy, squally, showers though.”
Yep – the “heavy, squally, showers” are here…
We just had more rain (by 3 millimeters) over the past 40 minutes than we have had over the past 24 hours. Very squally as well with big fat pregnant rain drops… the kind of rain drops which don’t so much ‘patter’ the roof, but rather splat into it sounding more like rotten seedless plums.

These lows dont really have an “eye” as such,yes it has a centre,sometimes cloud or clear skies with lesser wind but its the convection often circling it is the concern on windward coasts.

You’re quite right – it’s really only cyclones/hurricanes that have an eye.
