A strong southwesterly airflow lies over New Zealand on Tuesday, for the North Island naturally this leads to precipitation in the west and the South Island in the south. Showers also clip Banks Peninsula in the east and expect easing showers for Buller / Tasman.
Wednesday sees the standard scattering of showers for the western North Island again in a southwesterly airflow. The West Coast of the South Island isn’t all that wet during the day apart from a few showers north of Greymouth, it’s overnight that a greater chance of showers exists.
The below graphic shows the accumulated effect of where rain will fall over the next 3 days including today. Wet in the west, drier in the east.
