Stormy weather

September 9, 2013

An active front accompanied by heavy rain and gale force winds is expected to affect many parts of the country this week, and Severe Weather Warnings have been issued.

This front is set to approach the South Island on Tuesday before moving northeast to reach the lower North Island late Wednesday. The front is preceded by very strong northwesterly winds, with heavy rain about the West Coast spilling over the Southern Alps into the Otago and Canterbury Headwaters during Tuesday and Wednesday.

While the wettest weather is due in the west of the country, the strongest winds are expected in eastern areas. Severe northwest gales with gusts of 120-140km per hour are likely ahead of the front in the east from Wairarapa down through Canterbury and into Otago, and also about Wellington, Fiordland and Southland.

From the middle of the week, the strong winds and wet weather are focused on the North Island. A severe weather watch for heavy rain in Mt Taranaki, the Tararua Range, the central North Island high country and eastern Bay of Plenty has already been issued; also for prospects of very strong winds in Hawke’s Bay.

“It’s a real smorgasbord of weather this week, with gales, heavy rain and some pretty active thunderstorms in places,” said MetService communications meteorologist John Law. “The best advice for this week is to really keep an eye on the forecasts and warnings.”
