The North Island is in store for heavy rain and humidity as an area of low-pressure forms this week, Newshub reports. Long-range data also shows a moderate risk a tropical cyclone could develop, but even if a cyclone doesn’t form, the West Coast and North Island can expect heavy rain over the coming week. WeatherWatch head forecaster Philip Duncan says, “The only thing left to work out is precise tracking as that determines if the rain will directly affect NZ, or mainly fall nearby out at sea.”
