New Zealand is on the fringes of some aggressive weather according to forecasters at WeatherWatch.co.nz.

A shift in the weather patterns means big low pressure systems will form over the next week or two in the Tasman Sea and will brush the country bringing heavy rain, strong winds and possibly high temperatures.

The lows are expected to mainly dominate the southern Tasman Sea which will favour rain warnings to be issued along the West Coast and potentially in northern places such as the Tararua’s or Mt Taranaki. 

Strong winds may rise to gale force around hilly or mountainous parts of the South Island such as northern Southland, Otago and inland Canterbury. 

Those strong winds may also lead to a jump in eastern temperatures. 

WeatherWatch.co.nz says it’s a wait and see game but with the Spring Equinox arriving this week the spring-like weather is only just getting started.
