A TOTAL fire ban has been declared for Sunday, with severe fire conditions including wind and soaring temperatures sweeping through the Hunter.
The alert comes as Lake Macquarie police investigate three suspicious fires sparked on Saturday at Bennetts Green, Windale and Gateshead.
The first fire emerged between the inner city bypass and Lake Street at Windale, with the second emerging near Willow Road at Gateshead.
The third was between the Pacific Highway and Lake Street at Windale.
All three blazes were quenched but police are treating them as suspicious and urge anyone with information to call 1800 333 000.
A fire ban was also in force on Saturday.
There were no out of control bushfires in the Hunter at 8am on Sunday despite strong winds and dry conditions.
