MetService has issued Severe Weather Warnings for heavy rain and gales that are expected on Tuesday night and early Wednesday as several low pressure systems cross New Zealand.

“During Tuesday afternoon and evening, a low pressure system, formerly cyclone “Vania”, is expected to move onto the northern South Island,” commented MetService Weather Ambassador Bob McDavitt.  “This is expected to bring outbreaks of rain to the North Island and northwest of the South Island.  Heaviest falls are likely in the area from Westland to Nelson and across Marlborough,  as well as north Taranaki, the central North Island, and the main North Island ranges.”

This system is expected to merge with a mid-latitude low crossing Southland and then deepen east of Otago during Wednesday.

McDavitt went on to say that Tropical Cyclone “Zelia” is expected to rapidly leave the tropics on Monday evening and continue to weaken as it moves across the central or southern North island on Tuesday night or early Wednesday morning. “This is a fast-moving and rather small system. While it will no longer be a tropical cyclone when it reaches us, it may still pack a windy punch.”

The area that will get the strongest winds remains uncertain but is likely to include  Taranaki, Taumarunui, Taihape, and inland Wanganui.  A watch for possible severe gales has been issued for many other exposed North Island areas and also the Marlborough Sounds and parts of Nelson.

There is the potential for stormy conditions over much of the North Island, and also northern and western parts of the South Island.  People planning travel or outdoor activities in these areas should take into account the latest updates and warnings by checking the metservice.com website, or, for mobiles, on m.metservice.com.
