Sydney’s smoky week is set to continue through the weekend, with the haze from bushfires on NSW’s mid-north coast forecast to linger until Sunday. The air quality has been deemed “poor” today, following yesterday’s “hazardous” warning. Those with heart and lung disease are advised to stay indoors, keep their windows closed and avoid strenuous activity.

Strong winds tomorrow – forecast to peak at 40kmh in the middle of the day – will continue to push smoke haze over the city. But the Bureau of Meteorology has predicted the smog will start to clear on Sunday afternoon or evening, with rain and potential thunderstorms moving across the city. The wet weather will continue on Monday, dispersing the remaining fog.

More than 60 fires are burning across the state, with north-easterly winds blowing smoke south. The NSW Rural Fire Service says the smoke is “expected to settle in these areas and may continue for the next few days”. Several areas in NSW have a “very high” risk of danger from fire today.
