Weather Situation
A ridge lies across the coastal waters of NSW, extending from a high pressure system in the Tasman Sea. During Sunday, northerly winds will increase in strength as a cold front enters the far west of the state before slipping south. Then, another stronger cold front looks set to cross the coastal waters between late Tuesday and Wednesday next week, bringing a strong and gusty southerly wind change.
