For people in Lower West, South West and parts of Central West and South Coastal districts.

Issued at 4:00 pm Sunday, 1 July 2018.
Heavy rain and damaging winds possible over southwest WA from early Monday morning as a rain band and cold front move through.

Weather Situation:
An approaching rain band and cold front will affect southwest WA from early Monday morning. The system will bring the potential for heavy rainfall, damaging winds and abnormally high tides.

HEAVY RAINFALL that may lead to FLASH FLOODING is expected to develop southwest of a line from Bunbury to Walpole after about 5am AWST Monday morning as the rain band moves through. HEAVY RAINFALL should then extend as far north as the Perth area after around midday Monday, and through the remainder of the warning area by 5pm Monday. Rain should start to ease over southern parts of the warning area by Monday evening.
Northwesterly winds will strengthen early on Monday morning. DAMAGING WINDS to 100 kilometres per hour which could result in DAMAGE TO HOMES AND PROPERTY are possible southwest of a line from Bunbury to Walpole from about 5am AWST on Monday morning, most likely in exposed coastal areas.

Tides between Shark Bay and Cape Leeuwin are likely to rise above the normal high tide mark with very rough seas and potential flooding of low-lying coastal areas around the time of high tide from Monday morning through to the afternoon, particularly within Geographe Bay.
This is typical weather for this time of the year but heavy rain and winds may cause damage to property and make road conditions hazardous.

Locations which may be affected include Busselton, Bunbury, Collie, Geraldton, Mandurah, Manjimup, Margaret River, Moora and Perth.
Further cold fronts and a low are expected to affect southern and southwest parts of WA over the coming days with the potential for further severe weather on Tuesday morning and during Wednesday.
