WeatherWatch says stormy lows from the Southern Ocean, coupled with a cold change out of southern Australia, will combine to kick off what could become a ferocious storm, Newshub reports. By Tuesday it is likely to be very wet for large swathes of the country. Wednesday is when a cold change and severe gales will begin, with winds dying down by the weekend. In the North Island, Wednesday winds of 80-90km/h could be felt, rising to 140 km/h in some localised locations like the Manukau Heads in west Auckland.
