SMOKE from fires in New South Wales and northern Victoria is cloaking parts of the region.
Emergency Management Victoria has issued information for air quality in northern Victoria.
It says people might be able to see or smell smoke in parts of northern Victoria as a result of fires within the region and across New South Wales.
The air quality message said there was no immediate threat to the community, and no action is required.
However, EMV said some people were more sensitive to the effects of breathing in smoke.
It urged people who were sensitive to smoke to try to stay indoors where possible and to limit prolonged or heavy physical activity.
Those especially at risk include people with heart or lung conditions, including asthma, and pregnant women.
People over the age of 65 and children up to the age of 14 are also particularly sensitive to the effects of breathing in smoke.
EMV advised people with heart or lung conditions to take their medication as prescribed by their doctor.
"If you are asthmatic, follow your asthma plan and carry reliever medication with you," the community information message says.
Anyone experiencing wheezing, chest tightness and difficulty breathing should call Triple Zero (000).
People with concerns about their health were urged to seek medical advice or call Nurse on Call on 1300 606 024.
