Weather Video: Big Tasman Sea low to remain mostly offshore but some flooding risks

Filed in:

A large low has engulfed much of the Tasman Sea and peaks in size today and Wednesday - however it may not end up bringing many issues to NZ.

The low looks set to mostly remain offshore before unravelling on Friday as it moves into the upper North Island bringing only showers.

Forget the giant low in the Tasman Sea, the main threat this week to New Zealand comes from a sub-tropical northerly between this low and the blocking high to the east. The result? A burst of very slow moving sub-tropical rain for the Upper North Island starting tonight and not easing until Thursday.

A cooler south to south west flow is being felt across New Zealand today and is dragging in clouds to a few of our main centres and regions. Winds are a little breezy and cool with the odd isolated shower in the western North Island and few around western and eastern sides of the upper South Island.

A period of settled weather is expected for most parts of the country from Friday to Tuesday next week, despite a few lingering showers on Saturday in coastal areas.

Low pressure that has lingered all week over New Zealand is finally, slowly, about to drift away allowing a big high to roll in this weekend. 

The area of lingering rain will move away eastwards today and leaves the North Island from Thursday afternoon.
