STORM DETAILS
At 10:39pm on Sunday, 31 May 2026, the Bureau of Meteorology advised damaging to destructive winds remain likely across the south west land division into Monday morning.
Weather Situation: A deep and intense low pressure system is moving east along the southern coast tonight, bringing a significant burst of damaging to destructive winds to western and southern parts of the South West Land Division. As the low moves east during the morning, the risk of damaging winds is expected to shift towards southeastern WA, before easing overnight Monday night.
Widespread damaging westerly winds averaging 60 to 70km/h with gusts to 110km/h are likely to continue over western parts of the South West Land Division into early Monday morning.
Destructive wind gusts in excess of 125km/h are still possible over an area southwest of a line from Lancelin to Albany, including Perth, into early Monday morning.
The risk of damaging winds will shift from the west coast to inland parts of the South West Land Division, and to southern Goldfields, South East Coastal and Eucla districts during Monday, clearing from Perth and western districts before sunrise, then easing in the east on Monday night.
The winds associated with the low-pressure system through to Monday morning are expected to generate rarely experienced, widespread and damging to destructive conditions across southwest WA.
135km/h wind gust was recorded at Cape Naturaliste at 5:33pm.
133km/h wind gust was recorded at Cape Leeuwin at 4:56pm.
96km/h wind gust was recorded at Cowalellup at 10:06pm.

WHAT EMERGENCY SERVICES ARE DOING
-
DFES is monitoring the situation.
POWER
As at 5pm more than 30,000 customers across the network are currently without power in the Metropolitan and South West regions. Impacted customers are in the South West (including Donnybrook, Balingup, Bunbury, Augusta and surrounds), and Perth metropolitan (including Yanchep, Langford, Ferndale, Hamilton Hill, Gosnells and Stoneville and surrounds).
Western Power emergency response crews are working to address more than 160 hazards and outages caused by severe storm conditions.
The damaging and destructive winds associated with the storm front have thrown debris, including tree branches, into the network damaging equipment and bringing down powerlines.
Western Power have restored thousands of customers throughout the day but as the storm front continues, numbers may climb as damage is reported.
There are further damaging and destructive winds forecast throughout the evening, and we recommend affected customers prepare for extended outages with many customers expected to be without power overnight.
Western Power's priority is responding to reported hazards to ensure the safety of the community and our crews. Due to the severe weather and dangerous winds, Western Power crews cannot currently undertake repair works as it is unsafe to operate equipment like elevated work platforms or conduct network patrols via helicopter.
Western Power are communicating with impacted customers via SMS on updates including estimated restoration times and response efforts.
As numbers are fluctuating, for the latest information, visit https://www.westernpower.com.au/outages/
If you come across fallen powerlines:
Stay 8m away and make the safe call to Western Power on the emergency 24/7 number 13 13 51 so emergency response crews can attend the hazard and make the area safe
REQUESTS FOR ASSISTANCE (RFA)
DFES has received 647 SES requests for assistance as a result of the severe weather, with the highest number of reports coming from the Perth metropolitan area, followed by Peel, the South West and the Lower South West.
Requests have been received across a wide area, including Wembley, Kallaroo, Morley and Palmyra in the metropolitan area, as well as Capel, Australind and Collie in the South West.
Most requests are for roof damage, water ingress, fallen trees, structural damage and localised flooding.
DFES and SES crews are prioritising jobs where there is a risk to life or property. They are responding as conditions allow, with damaging winds continuing in some areas, which may affect how quickly crews can safely attend.
SUPPORT INFORMATION
If it is safe to do so, the community are asked to do what they can to help themselves before calling the SES for assistance.
If your home has been badly damaged by a storm, call the SES on 132 500.
In a life-threatening situation, call Triple Zero (000).
Please note the SES does not assist with fallen fences. Please contact your insurer for assistance with fences.
After a storm, SES volunteers make temporary repairs to homes that have been badly damaged, such as roofs that have been ripped off or large fallen trees on homes or cars. Please contact your insurance company to organise permanent repairs.
KEEP UP TO DATE
During a power outage, your home phone, computer or other electronic devices connected to the NBN will not work. Include a battery powered radio in your emergency kit.
Updates will be provided when the situation changes.
