Gale warning in effect for Cook, Castlepoint, Puysegur, Foveaux and Chatham Islands
The Situation
Today, a low pressure system passes northeast of the country, while unsettled westerlies persist over southern New Zealand. The low moves away to the east tomorrow, and a southwesterly flow over the country weakens as high pressure approaches from the Tasman Sea.A ridge of high pressure covers the country during the weekend. On Monday, the high remains over northern and central New Zealand, but a front over the southern ocean reaches the south of the South Island at night, a moist northwest flow strengthens over the far south ahead of the front. During Tuesday, the front moves northwards over the South Island and weakens, while the ridge of high pressure remains over northern New Zealand.
