The Department of Biodiversity, Conservation and Attractions has issued a smoke alert from Perth to Mandurah.
The smoke is due to a combination of prescribed burns by Parks and Wildlife Service as well as private property burn-offs.
It is expected to clear by tomorrow morning.
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 when travelling 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.
