RainWatch Tuesday: Useful showers continue for north of NI; mostly dry elsewhere

A ridge of high pressure pushing on to the South Island and the southern half of the North Island on Tuesday will bring dry weather there.

It’s a slightly different story for the top half of the North Island north of a line from about New Plymouth to Whakatane.

A weak trough of low pressure west of Waikato will encourage the development of showers across those more northern regions, and the showers could become more prolonged towards the end of the day as easterly winds pick up.

The good news is that by 6am tomorrow another 10 to 15mm of rain may have fallen across Northland and the Coromandel, with 5 to 10mm for Auckland and the Waikato.

A few light showers around the edge of the ridge of high pressure are also possible along the Southland coast and the Buller coast north of Karamea.

Further rain relief as the week goes on could bring another 20mm of so to parts of Auckland and Northland by Thursday morning.
