Severe weather warning, 100 km/h winds for Southwest

According to the Bureau of Meteorology, the cold front is forecast to affect the southwest section of the state from Thursday afternoon and evening.

The weather system is likely to cause widespread damaging winds up to 100 kilometres per hour that could result in damage to homes and property.

The winds are likely to develop around the Southwest Capes before extending throughout the remaining parts of the southwest going into Thursday night.

In isolated areas, dangerous gusts travelling more than 125km/h are possible, and could cause significant destruction to homes and property.

Thunderstorms are also possible in the evening throughout the warning area. Moderate falls may occur over the South West, with dangerous surf conditions likely to develop along the entire coast.

The storm is expected to reach as far as Albany.

The Bureau said the overall weather pattern is not unusual for this time of year, but severe weather may occur in some parts of the warning area.

The Department of Fire and Emergency Services advises anyone travelling south to:

- 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.
