For people in Lower West, South West, South Coastal and parts of Great Southern and Central Wheat Belt districts.

Issued at 4:09 pm Monday, 4 May 2020.

The first widespread cool season weather event to affect Perth and Southwest WA this year is likely from late Tuesday, extending into Wednesday.

A deep low-pressure system and associated cold front are approaching the south west corner of Western Australia. The system will bring very strong, gusty winds and a cold, unstable airmass to the Southwest Land Division from late Tuesday.
Gusty showers will develop from Tuesday morning ahead of the system, with isolated thunderstorms developing later in the afternoon and small hail possible about the southwest corner from Wednesday morning.

WIDESPREAD DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts to around 100km/h are likely and could cause DAMAGE TO HOMES AND PROPERTY.

Locally DANGEROUS WINDS, averaging 80 to 90 km/h with peak gusts in excess of 125 km/h are possible and could cause SIGNIFICANT DAMAGE OR DESTRUCTION TO HOMES AND PROPERTY.

These winds are expected to develop in western parts of the warning area from late Tuesday afternoon and extend to remaining parts of the warning area by the evening.

HIGHER THAN NORMAL TIDES may cause FLOODING OF LOW-LYING COASTAL AREAS within the warning area from early Wednesday morning.

DAMAGING SURF CONDITIONS are also likely from Tuesday afternoon through Wednesday morning, which could cause SIGNIFICANT BEACH EROSION about coastal locations within the warning area.

Locations which may be affected include Albany, Bunbury, Busselton, Katanning, Mandurah, Manjimup, Margaret River, Mount Barker, Narrogin, Northam and Perth.

This front is expected to be windier than a typical cold front and is likely to produce the kind of weather that is only seen in Southwest WA about 2 times per year.

The Department of Fire and Emergency Services advises that people should:
* 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.
