VIGOROUS WINDS DEVELOPING OVER SOUTHEAST NEW SOUTH WALES

Weather Situation: Two cold fronts are forecast to cross southern New South Wales over the coming days: one on Thursday morning and a second overnight Friday into Saturday morning. Vigorous northwest to southwesterly winds are expected with these two systems, with winds only easing later Saturday after the passage of the second front.

DAMAGING WINDS, averaging 80 to 90 km/h, with peak gusts in excess of 120 km/h, are expected over Alpine areas above 1900 metres from late Wednesday afternoon.

For areas below 1900 metres, DAMAGING WINDS, averaging 60 to 70 km/h, with peak gusts in excess of 90 km/h, are possible from Thursday for the Illawarra, northern parts of the South Coast, eastern parts of the Central Tablelands (including the Blue Mountains) and parts of the Southern Ranges.

Winds are forecast to ease during Saturday following the passage of the second cold front.

BLIZZARDS are likely for alpine areas above 1700 metres from Wednesday evening. Blizzard conditions are currently forecast to ease by Saturday evening. The NSW National Parks and Wildlife Service recommends that back country travel be postponed until conditions improve.
