Last Month of Spring to Deliver a Drenching Across WA
A strong weather system is moving across Western Australia this week, bringing widespread thunderstorms, heavy rain, and hail. Some regions may see up to 50 millimetres of rainfall through Thursday night.
The storms are forming from a trough and a low-pressure system just off the west coast. Earlier this week, this same system brought a spell of warm and sunny weather before shifting into more turbulent conditions.
Regions Most Affected
- Areas south of Carnarvon are expected to receive the heaviest rainfall, reaching around 50mm over the next two days.
- Lightning and patchy showers have already begun in regions south of Perth, with renewed storm activity expected overnight.
Weather Pattern Development
Over the weekend, a trough formed along the west coast, creating fine conditions across much of the state. However, as a low-pressure system developed within that trough on Monday, the pleasant spell quickly shifted to stormy weather.
“The eastern side of a trough line is a really good spot for thunderstorm development,” meteorologists noted, explaining the sudden shift from warmth to storms.
Spring’s Final Weeks
The final month of spring has showcased diverse weather for Western Australia, moving from balmy evenings to vivid lightning displays and heavy downpours.
