Peak winds of up to 100 kilometres per hour are possible, with gusts likely to average between 60-70km/h.
The front brings about a small chance of hail, with rainfall totals up to 50mm a possibility.
Tides between Mandurah and Albany are expected to rise above the normal high tide mark, but the Department of Fire of Emergency Services (DFES) claims the front is not as strong as the weather that battered the state's south earlier this week.
DFES urges residents to store or weigh down loose objects around the home, while ensuring pets and animals are in a safe area.
If your home is badly damaged by a storm, call the SES on 132 500.
