Very strong winds are currently being felt over the southwest corner and the metropolitan area.

These are expected to last throughout the evening and into Wednesday morning.

High tides could cause flooding from early Wednesday morning and damaging surf conditions could cause significant beach erosion.

Th front will bring conditions only seen in the southwest of the state about twice a year.

The Department of Fire and Emergency Services advises:

• 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.
