A grassfire which broke out in western Sydney is nearly under control and no properties are under threat, the RFS says.
The fire started in an inaccessible area in Penrith on Thursday, with crews having some difficulty getting to the location, an RFS spokeswoman told AAP.
"It's a small fire that was burning very slowly," the spokeswoman said.
Firefighters had created a perimeter around the fire, at Coombes Drive and Hickeys Lane, and it was very nearly contained as of 7.15pm (AEDT), she said.
"There are no threats to any property," she added.
It comes as a total fire ban was declared for the Sydney area and the vast majority of the state on Friday with temperatures predicted to soar into high 30s and low 40s.
As of Thursday night, 84 fires were burning across NSW of which 14 were uncontained.
