The Department of Biodiversity, Conservation and Attractions have issued a smoke alert from Bunbury to Perth, including Mandurah.
The smoke is due to prescribed burns being carried out by the Parks and Wildlife Service in the South-West today.
It is expected to clear overnight.
WHAT TO DO:
If the smoke is particularly thick, it is recommended people shut doors and windows and turn off air-conditioners.
Smoke may reduce visibility on some roads and motorists should take care, turn on headlights and travel at appropriate speeds in these areas.
People with asthma and pre-existing respiratory or cardiovascular illnesses should follow their pre-prepared treatment plan.
People with conditions exacerbated by smoke should take precautions in line with their medical advice for these circumstances.
