Severe Weather Warning
for Damaging Winds And Heavy Rainfall

for parts of Lower West and South West districts.

Issued at 4:43 pm Friday, 1 August 2025.

Isolated damaging winds and heavy rainfall possible with a cold front early Saturday. A second stronger front expected on Sunday.

Weather Situation
Gusty lines of showers and thunderstorms are expected to develop about a cold front approaching the far South West coast early Saturday, reaching the Lower West district mid-morning before weakening. A second more vigorous cold front will push across the South West during Sunday morning, bringing a broader risk of damaging winds to the region.
DAMAGING WINDS and HEAVY RAINFALL for the following areas:
Lower West and South West
From early Saturday morning: DAMAGING WIND GUSTS in excess of 90 km/h are possible with showers and thunderstorms about coastal parts of the South West district before sunrise, extending northwards to parts of the Lower West including Mandurah mid-morning. A period of moderate to HEAVY RAINFALL which may lead to flash flooding is also possible along the front. Six-hourly rainfall totals between 25 to 35 mm are likely with isolated falls up to 50 mm possible. Conditions are expected to ease by midday.
From late Saturday evening: DAMAGING WESTERLY WINDS averaging 55 to 65 km/h with peak gusts around 100 km/h are expected to redevelop between Cape Naturaliste and Walpole as the second front approaches the far South West. This risk may extend more broadly on Sunday to coastal parts between Lancelin and Albany, including the Perth region.
The first cold front on Saturday is typical for this time of year. For the second front on Sunday, people in the southwest of WA usually experience a front as windy as this about 5 times per year.
Locations which may be affected include Bunbury, Busselton, Mandurah, Margaret River, Augusta and Dunsborough.

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.

The next Severe Weather Warning will be issued by 11:00 pm AWST Friday.
Warnings are also available through TV and Radio broadcasts, the Bureau's website at www.bom.gov.au or call 1300 659 210. The Bureau and Department of Fire and Emergency Services would appreciate warnings being broadcast regularly.
