Updated — A deep low pressure system moves close to the upper North Island today pulling in a strengthening southeasterly airflow, meanwhile the South Island sits under a ridge of high pressure with a weakening front moving onto the far south. Basically a low pressure system is merging with a ‘squash zone’ of wind.
