Western Australia is bracing for a wild few days of intense wind, rain, thunderstorms and waves with potential for significant damage, according to weatherzone.com.au.
From Tuesday night to Friday the wind, rain and storms will be far reaching across the west and south of the state but focused on the southwest, particularly the area from Perth to Albany.
"Wind will be strong enough to damage buildings and bring down trees and power lines. Storms will be intense enough to enhance the wind and rain and lead to flash flooding. And waves will be large enough to erode beaches. There is potential for wind gusts to reach 120km/h, rainfall to amount to 60-to-120mm and wave heights to exceed five metres," Weatherzone meteorologist Brett Dutschke said.
There is still time to do some tidying up around the yard and clean the gutters before the peak of the weather hits on Wednesday.
"The effects could be similar to that of a cyclone. It looks like being the most intense low pressure we have seen in the southwest since last spring or winter. A pool of cold air from the south is about to interact with warm, moist air from the north to form the intense low," Dutschke said.
The region between Perth to Albany should cop the brunt of the wind and rain. Most places should pick up more rain than last week. Some will pick up their biggest rain in more than a year with 50-to-100mm likely and a chance for more than 100mm. Flooding could occur in low-lying coastal areas such as Busselton and Dunsborough.
Although the battering will generally be in southern parts of WA, the wild weather will penetrate a long way north and east.
"As far as the Gascoyne and Goldfields, 25-to-50mm of rain is possible. Wind damage is also a significant risk, mainly with the threat of severe thunderstorms," Dutschke said.
This will bring an end to an unseasonably warm spell. Some areas have experienced their warmest May weather in more than a decade and it is about to become wintry. Kalgoorlie should reach 31 degrees on Tuesday before struggling to reach 16 degrees on Sunday.
