Area Description:
Inshore waters from Lyttelton Harbour to the Waimakariri River mouth.
Situation:
A low pressure system from the Tasman sea crosses the North Island today. Meanwhile, a broad trough following the low moves onto the South Island and moves south of the Chatham Islands tomorrow as it deepens into a low. On Wednesday, a southwest flow over New Zealand eases as a high over the Tasman Sea extends a ridge over the country. The high moves onto New Zealand during Thursday and lies across central New Zealand on Friday. Meanwhile a front from the south approaches the South Island, and an easterly flow strengthens over the north of the North Island.
