A vigorous low pressure system and associated cold front is expected to move through NSW on Thursday, with damaging winds forecast around the low pressure system as it moves through inland NSW, as well as with the front as it passes over the NSW ranges. Widespread rain and showers and isolated thunderstorms are also likely with this system.

Winds averaging 60 to 80 km/h with peak gusts in excess of 110 km/h are expected about Alpine peaks from Wednesday night.

Winds averaging 50 to 70 km/h with peak gusts in excess of 90 km/h are expected to develop Thursday morning in the far west of New South Wales, progressing through the central inland and central ranges in the afternoon. Districts affected include the Upper and Lower Western, Riverina and parts of the Central West Slopes and Plains, Central Tablelands, Upper Hunter.

Moderate to locally heavy rain is expected to develop early Thursday morning over already saturated catchments about the Central West and the South West Slopes. This may lead to localised flash flooding as well as contribute to broader riverine flooding. Districts affected include the South West Slopes and adjacent parts of the Central Tablelands, Central West Slopes and Plains and Snowy Mountains districts.
