Caution

Weather Situation
A deep low pressure system over the Tasman Sea is bringing large and powerful waves to the entire coast and fresh southerly winds to the northern part of the coast, while winds tend northerly along the southern part of the coast ahead of a cold front approaching from the west. Tomorrow a series of cold fronts will brush the southern part of the coast while a ridge builds over the northern part of the coast, before winds tend southwesterly along the entire coast Wednesday as the ridge widens to the entire coast. This ridge will persist through the end of the week with winds tending southerly then southeasterly.
