Long-awaited rainfall for the upper South Island

Long-awaited rainfall for the upper South Island

Over the past 36 hours there has been significant rainfall across the northern two-thirds of the South Island, with well over 150mm around Greymouth and the Alps and more to come.

“This rain sticks around for many areas until Saturday,” said MetService forecaster Cameron Coutts. “Further south, however, it is looking fine and dry for the third one day international cricket match in Dunedin.”

A number of Severe Weather Warnings and Watches remain in force for heavy rain. Although this rain will help alleviate the drier conditions some regions have been experiencing, unfortunately it has come too late for some farmers in Buller and northern Westland.

“On Sunday, the rain finally clears in the west and most of the South Island will be fine,”
commented Coutts. “Warm temperatures remain for western areas, with the likes of Westport and Hokitika getting a week of temperatures reaching more than 20C.”

This generally warm flow will also affect temperatures in the upper North Island. Most places there can expect a return to above-average temperatures, with many inland places reaching well into the upper twenties. However, these warmer temperatures will also bring an increase in shower activity for inland areas of the North Island, some of which may develop into thunderstorms.

Heading into next week, MetService is keeping a close eye on a low developing over the Tasman Sea. There’s a chance that this low could bring heavy rain to northern and western areas of the country mid next week. There is still some uncertainty with this system this far out, so keep up to date with the latest forecasts.
