The first storm of the season is about to hit the west coast, and it's set to pack a punch.
A cold front has been building off the coast for the past few days and is due to make impact tonight.
The strong weather system is expected to bring damaging winds with gusts to 100 kilometres per hour which could result in damage to homes and property in the Perth Metropolitan area around 8pm.
Tides are likely to rise above the normal high tide mark with very rough seas, while thunderstorms and heavy rainfall will also accompany the passage of the front.
24-hour rainfall totals to 9am Friday are expected to be between 20 and 40 millimetres with totals exceeding 50 millimetres in some areas.
The advice from the Department of Fire and Emergency Services is:
* If outside find safe shelter away from trees, power lines, storm water drains and streams.
* Close your curtains and blinds, and stay inside away from windows.
* Unplug electrical appliances and do not use land line telephones if there is lightning.
* If boating, swimming or surfing leave the water.
* Be alert and watch for hazards on the road such as fallen power lines and loose debris.
* Keep away from flooded drains, rivers, streams and waterways.
* Be careful of fallen trees, damaged buildings and debris.
* Be careful of fallen power lines. They are dangerous and should always be treated as live.
* Assess your home, car and property for damage.
* If damage has occurred take photos and contact your insurance company to organise permanent repairs.
* If your home or property has significant damage, like a badly damaged roof or flooding, call the SES on 132 500.
