View the current warnings for New South Wales

Forecast issued at 4:05 am EDT on Monday 22 December 2014.

Weather Situation

A high pressure system over the Tasman Sea will drift slowly east during the coming days, while maintaining a ridge towards the Queensland coast. This will generate freshening north to northeasterly winds along the Sydney coast before a trough developing near the state's western border shifts eastwards and brings a short-lived southerly change mid-week. A cold front looks likely to bring a more vigorous southerly change during Friday.

Forecast for Monday until midnight
