- Weather Situation
- Fresh and gusty southerly winds are persisting in the wake of a cold front that crossed Sydney Waters this morning. Winds will turn east to northeasterly on Tuesday as a weak trough forms near the coast. This trough will then deepen to a low pressure system near the central parts of the coast late Tuesday before quickly moving offshore. This will be followed by a high pressure ridge building across the state, which will become the dominant feature mid to late this week until the next trough brushes the coast on the weekend.
