UPDATE: EASING weather conditions have helped firefighters control a bushfire burning near Wyong on the NSW Central Coast.

More than 60 firefighters and six water bombing aircraft have been battling the blaze and protecting homes between Bumble Hill Road and Forest Road at Kulnara northwest of Wyong.

A watch and act alert was issued early yesterday afternoon but that was reduced to an advice later yesterday.

The Rural Fire Service said conditions had improved and the immediate threat to properties had eased.

But in an advice it warned residents in the area that embers may be blown ahead of the main fire front to start spot fires that could threaten homes.
