MetService forecasters expect a large low to have a major effect on New Zealand’s weather from Sunday through to Tuesday or Wednesday. “Here comes one of the bigger weather events we are likely to see for a while”, commented MetService Weather Ambassador Bob McDavitt. “Much of New Zealand will feel the presence of this low over the next few days.”

In the lead-up to the main event, MetService has issued a Severe Weather Warning for easterly gales and more heavy rain over the north of the North Island on Sunday and Gisborne Monday. “About another 100 mm of rain is expected on top of the 100 mm or so that fell just a few days ago”, said Mr McDavitt.

“However, the biggest rainfalls are likely to be in Nelson, Marlborough, Canterbury and Otago on Monday and Tuesday. While it’s still early days, some of these areas could have substantial rainfall totals – up to around 200 mm”, explained Mr McDavitt. MetService has therefore issued a Severe Weather Watch for this event and will provide more advice in a Severe Weather Warning on Sunday.

Added to this, on Monday easterly gales are also expected in all western North Island areas from Auckland to Kapiti, including the central North Island, and also in Nelson, Buller, Westland, Marlborough and Canterbury. These gales may become severe in some areas, particularly Taranaki, Manawatu and the Kapiti Coast, valleys of Buller and Westland and about Banks Peninsula.

People are urged to stay up-to-date with the latest MetService forecasts and warnings. Streams and rivers will rise quickly and there could be surface flooding in low lying areas. The combination of heavy rain and gales is likely to make driving hazardous, cause slips in hilly areas and damage trees and powerlines.
