- Weather Situation
- A high pressure system over the Bight will gradually strengthen as it moves eastwards over the next few days, reaching the Tasman Sea by the weekend, maintaining south to southeasterly winds over the Sydney waters for much of the period. Meanwhile, a weak coastal trough will develop along the NSW coast later today and into Thursday. Winds will tend east to northeasterly by early next week as the high moves further into the Tasman Sea.
