A SMOKE alert has been issued for the northern suburbs caused by a prescribed burn in the Gnangara Pine Plantation.
The Parks and Wildlife Service at the Department of Biodiversity, Conservation and Attractions has issued a smoke alert for Mariginiup, Tapping, Ashby, Sinagra, Wanneroo, Jandabup, Gnangara and surrounding roads.
The smoke is the result of a DBCA prescribed burn in Gnangara Pine Plantation and is expected to clear by tomorrow morning.
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.
