A widespread series of rain warnings and watches are in effect for portions of the North Island beginning Friday, as humid conditions are forecast to move across the country.
Heavy Rain Warnings Issued
MetService has issued an orange heavy rain warning for the Bay of Plenty east of Ōpōtiki and for Gisborne/Tairāwhiti north of Tolaga Bay, beginning at 8pm Friday and extending into Saturday. The forecaster anticipates rainfall accumulations of 80 to 100 mm, with the possibility of 130 to 150 mm in localized areas.
Yellow heavy rain warnings have also been issued for Northland, Auckland (including Great Barrier Island), Coromandel Peninsula, Waikato, Waitomo, Gisborne/Tairāwhiti from Tolaga Bay southwards, Manawatū, Tararua District and Hawke’s Bay throughout Friday.
MetService notes that these conditions could lead to the development of thunderstorms and localized downpours, which, whereas currently assessed as low to moderate risk, could have significant impacts.
South Island Weather Outlook
A front moving across the South Island on Friday is expected to bring heavy rain to western areas, with some precipitation extending east of the Alps. A southerly change on Saturday will bring showers and potential thunderstorms to Otago and Canterbury.
Meteorologist Alwyn Bakker indicated that the forecast position could change daily.
Temperature Shift Expected
While temperatures remain high across both islands, with a heat alert issued for Upper Hutt and highs of 28C in Invercargill and 30C in Alexandra, a shift is anticipated this weekend. Cooler air is expected to move up from the south, potentially resulting in a temperature decrease of more than ten degrees in some South Island locations between Friday and Sunday. These cooler temperatures are expected to extend into early next week.
