Several orange-level weather warnings have been issued as a “significant storm” moves across New Zealand on Labour Day, bringing heavy rain and strong wind to many regions, including heavy snow to the Canterbury High Country.
MetService said the active low pressure system would impact large areas of the country on Monday and Tuesday.
Heavy rain warnings were in place for the central North Island hill country, Taranaki Maunga, the Tararua Range, and the Richmond and Bryant Ranges. Further south, warnings covered the headwaters of Canterbury’s lakes and rivers, the ranges of Westland north of Haast, and the ranges of Grey and Buller, along with western Tasman. Some areas recorded rainfall totals exceeding 150mm.
A heavy snow warning was issued for the Canterbury High Country south of SH73, where snow fell Monday afternoon and evening, settling above 500 metres.
Strong wind warnings were in effect for Wairarapa, the Tararua District and Wellington, with gusts reaching up to 130km/h in exposed areas.
Watches were also in place for heavy rain in the eastern ranges of Bay of Plenty, and for strong winds across Hawke’s Bay, Gisborne, South Taranaki, Taihape, inland Whanganui, Marlborough, Nelson, Tasman, Banks Peninsula and parts of the Canterbury High Country.
These warnings follow a brief reprieve after days of severe weather wreaked havoc across the country.
A state of emergency remained in place for Southland, the Clutha District, and the Kaikōura District as nearly 15,000 properties in the lower South Island remain without power after severe weather downed trees, damaged homes and shut down more than 100 cell towers on Thursday.
