Perth blanketed by heavy smoke

A smoke alert was issued for parts of Perth overnight following prescribed burns in the area.

The Department of Parks and Wildlife issued a smoke alert for Two Rocks, Rockingham and the Perth Hills.

Main Roads WA closed some roads due to poor driving conditions.

The smoke is expected to clear later today.

The department will undertake more prescribed burns this afternoon.

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.
