Updated 11:35pm — A small but quite intense area of heavy downpours & isolated thunderstorms is approaching the western North Island early Sunday morning, mainly between New Plymouth and Hamilton but may affect western areas from Taranaki to Auckland. Northland has some risk too, although much lower.
At this stage the Forecast Rain Radar suggests the Waitomo region may be most exposed, but the rain area we’re monitoring is still well offshore and unstable, so current flare ups that we can see now may ease before landfall while new areas flare up. It’s not a repeat of what happened in Auckland the other day.
Highest risk for thunderstorms and/or intense downpours looks to be mainly around 3am +/1 an hour or two. It should weaken then as it tracks eastwards over land.
