More areas of New South Wales have been given a catastrophic fire danger rating, as high temperatures and winds reach their peak.
The northern and eastern Riverina and southern parts of the lower central western plains will stay at catastrophic levels for several hours before a cool change later tonight.
The Rural Fire Service says people in these areas should avoid bushland areas and ensure they know what to do if a fire threatens their area.
The Illawarra, Shoalhaven and southern highlands remain under a catastrophic fire danger rating.
More than 100 bush and grass fires are burning across NSW, with a number burning out of control.
Four emergency warnings are in place for fires at Munyabla, Tarcutta, Brogo and the Kybean Valley.
Six Watch and Act alerts have also been issued for fires burning across the Riverina region.
A total fire ban has been declared across the state.
