Weather Situation
A ridge extends from a high situated over New Zealand, maintaining northeasterly winds. The ridge is expected to be the dominant feature through the week, as a series of high pressure systems pass to the south. Then, a cold front looks set to cross the local waters on Sunday, bringing a fresh southerly change.
