Wet and stormy week for Western Australia
Monday 13th July 2020
The South West Land Division of Western Australia is bracing for a wet and stormy week, with a series of cold fronts expected to batter the region from tonight onwards.
Today, a pre-frontal trough will trigger scattered showers across parts of the South West Land Division ahead of an approaching cold front expected to move through this evening.
Instability will increase across the west coast ahead of this advancing cold front, generating a large band of shower and storm activity this evening and into Tuesday morning. Whilst widespread severe storms aren?t expected, locally damaging winds gusts will be possible.
Locally heavy falls are expected to develop tonight, particularly between Perth and Bunbury, with widespread falls of 15-30mm expected with isolated heavier falls to 50mm possible, particularly with storm activity. This may lead to flash flooding for some locations.
Late Monday and into Tuesday, wind gusts will also pick up across the region, with gusts approaching 90km/h across exposed coastal locations and elevated terrain, before gradually easing late Tuesday.
Whilst calmer conditions will return on Wednesday, it will be short-lived as secondary front approaches the region during Thursday. Another band of showers and thunderstorms will accompany this front, bringing the threat of locally severe storms and further heavy falls. Further totals of 15-30mm are expected to develop, with isolated falls of up to 50mm possible for some locations.
