There's a current Smoke Alert for the Swan Coastal Plain from Yanchep to Mandurah, including the Perth Hills in the Perth Metropolitan Area.
The smoke is due to prescribed burns being carried out in the Perth Hills. The smoke is expected to clear 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.
