The MetService is warning of more intense rain, high winds, and thunderstorms across much of the country. Heavy rain warnings are in place for Westland, the headwaters of the Canterbury lakes, the rivers around and south of Arthur’s Pass, and Fiordland (north of Doubtful Sound). The weather system is likely to affect the many of the same areas which had already seen a lot of rain in recent days. Once the current system pulls away to the east, the winds will change from a northerly to a southerly which will drop temperatures across the country.
