Sydney and much of the NSW coast is being pummelled by wild weather, with the wintery spell forecast to spread across the state and to the ACT and Victoria later.
After Sydney and Melbourne had an early taste of spring over the weekend, with warm temperatures setting records, wet weather has now moved in.
In Sydney mid to high 20s temperatures have dropped more than 10C to around 14C.
It's being dubbed a 'bomb cyclone" because of the rapid onset of severe weather.
