High pressure covers most of New Zealand today, it slips away to the north a little on Tuesday as a northwesterly airflow gradually builds and a front moves onto the lower South Island. A low and front combination moves out of the Tasman Sea and affects the South Island on Wednesday while a northwesterly airflow lies over the North Island.
Blue – Isolated showers develop about parts of the upper North Island this afternoon, some may become heavy with thunderstorms (especially inland) then easing later this evening and clearing overnight.
Blue – Isolated showers once again form over some upper North Island areas (inland once again being the best spot for this), this time the risk isn’t as large however there is still a chance of a heavy fall or thunderstorm.
Heavy rain moves onto Fiordland overnight.
Blue – Heavy rain spreads northwards along the West Coast of the South Island during the day, easing later in the evening.
Purple – Northwesterlies through Cook Strait will be strong with a risk of winds gusting to gale at times.
– Please note, the idea behind this update is to focus on the main weather highlights, which is why not all regions are mentioned.
