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

Issued at 4:32 pm Sunday, 8 November 2020.
Damaging winds and heavy rainfall are possible across southwestern WA with the passage of a cold front on Monday.

Weather Situation: A cold front approaching from the southwest is likely to produce gusty showers and thunderstorms as it moves across southwestern WA during Monday morning and afternoon.

Thunderstorms associated with the front may produce DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts to around 90 km/h, which could cause DAMAGE TO HOMES AND PROPERTY.

Thunderstorms are most likely to occur on the frontal boundary, which is expected to move across the South West Capes around sunrise, moving northward to reach Mandurah in the late morning and then extending eastwards across the Central Wheat Belt, Great Southern and South Coastal districts during the afternoon.

Showers and thunderstorms associated with the front may also produce HEAVY RAINFALL southwest of a line from Bunbury to Windy Harbour which may lead to FLASH FLOODING during Monday morning.

Gusty conditions will continue across southwestern WA in the wake of the front.

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

This weather is typical of a winter-time cold front, but is occurring unseasonably late in the 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.

* 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.

* 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.
