Greater Sydney region to be under catastrophic fire danger on Tuesday after NSW bushfires kill 3

The greater Sydney region will be under catastrophic fire danger on Tuesday for the first time since new fire ratings were introduced a decade ago, after a horror weekend which saw three people die in NSW bushfires.

More than 60 bush fires continued to burn across the state on Sunday night as conditions eased, with all of the blazes at "advice" and "watch and act" alert levels.

The New South Wales Rural Fire Service says catastrophic fire danger is forecast for the greater Sydney and greater Hunter regions - including the Blue Mountains and the Central Coast - for Tuesday due to worsening conditions.

Rural Fire Service spokesman Anthony Clark told ABC on Sunday catastrophic is as bad as it gets. Homes are simply not designed to withstand fire under those conditions.
