The Total Fire Ban, which started at midnight, covers the following councils: 

Greater Hunter (severe) — Cessnock, Dungog, Lake Macquarie, Maitland, Muswellbrook, Newcastle, Port Stephens, Singleton and Upper Hunter.

The NSW Rural Fire Service (NSW RFS) provides the following advice:

Under severe and very high fire conditions –

* Well prepared homes that are actively defended can provide safety during a fire;

* Follow your Bush Fire Survival Plan and remain vigilant; and

* Keep informed by listening to local radio, watching television news broadcasts and monitoring www.rfs.nsw.gov.au

The NSW RFS may issue a Harvest Safety Alert for areas of heightened risk. 

Harvest operators should monitor conditions and regularly check that they are operating within guidelines.

No fires may be lit in the open and all fire permits are suspended during a Total Fire Ban. Gas and electric barbeques may be used provided certain conditions are met.
