Weather Situation
A trough is located off the northern half of the coast bringing fresh southeasterly winds to Sydney waters. This trough is set to weaken over the course of the evening as a ridge builds over the NSW coast. This ridge will persist through the middle of next week as winds gradually tend southerly for Sydney waters.
