Fierce winds will impact a large area of southeastern and eastern Australia during the next 48 hours as a wintry blast continues over the region.  

This wild and dangerous weather is being caused by a deep low pressure system in the Tasman Sea and a series of low-pressure troughs and fronts extending over southeastern Australia.  

Powerful winds will impact several states and territories on Tuesday and Wednesday, with several severe weather warnings currently in place.  

The map below shows one model’s instantaneous wind gust forecast on Tuesday afternoon, showing the broad extend of the dangerous winds from this system.

Severe weather warnings have been issued for damaging winds in parts of SA, VIC, eastern NSW, the ACT and southeast QLD on Tuesday. Winds across the higher ground and Hunter district in NSW could see winds averaging 50 to 70 km/h (about 38 knots), with gusts to 110 km/h. Coastal areas across Sydney and the Illawarra could see winds averaging around 45 to 65 km/h (about 35 knots), with gusts around 90 to 100 km/h.  

Damaging winds should continue into Wednesday across parts of VIC, NSW, the ACT and QLD, before easing on Thursday as a high pressure system moves across the region.
