Locals are being warned to prepare now for severe weather set to hit from Thursday morning.
The storm advice includes coastal areas from Rockingham down to Esperance including Mandurah.
The Bureau of Meteorology said a strong cold front is approaching which could produce damaging winds gusts of around 90 to 100km/h.
Conditions are expected to ease late Thursday evening.
WHAT TO DO
• Pack away, secure or tie down outdoor furniture, trampolines and other loose items around your home that could be picked up and thrown by strong winds.
• Prepare an emergency kit with a radio that runs off batteries, a torch, spare batteries and a first aid kit. For more information visit emergency.wa.gov.au/prepare.
• Trim branches around your home to prevent them falling on your roof or car.
• Clear gutters and downpipes so they do not overflow after heavy rain.
• Boat owners should securely moor their boats.
